Frontized™

Frontend Starter kit with useful additional CSS and JS Scripts

I realised I was doing the same thing over and over when starting a new build so decided to create my own mini package which has the basics for starting a simple static or dynamic web site.

The first version of Frontized, (at that time named Bootstrap Extended, later referred to as Frontized) made its debut on Sep 10, 2015.

NOTE that this package has a dependency Bootstrap 3.1 which already installed as well.

Folder structure

Folder structure

Folder structure standard conventions varies by build system and programming language.

src/:

"source" files to build and develop the project. This is where the original source files are located, before being compiled into fewer files to dist/, public/ or build/.

NOTE: The advantage on using partials is that you can use many files to organize your code and everything will be compiled on a single file. see SCSS folder for understanding

dist/: = Assets folder

"distribution", the compiled code/library, also named public/ or build/. The files meant for production or public use are usually located here.

lib/:

external dependencies (when included directly).

test/:

the project's tests scripts, mocks, etc.

vendor/:

dependencies are usually put here via dependency management.

bin/:

files that get added to your PATH when installed.

package.json:

describes library and dependencies (if a JS package).

composer.json:

same as above but for PHP packages via composer.

.travis.yml:

config file for the Travis CI environment.

.gitignore:

Specification of the files meant to be ignored by Git.

Bootstrap modal appearing behind backdrop

The issue has to do with the positioning of the parent containers. You can easily "move" modal out from these containers before displaying it. Here's how to do it if you were showing modal using JS.

jQuery( document ).ready(function() {
    setTimeout(function(){ /* Timeout is optional (*need to in some case if its not work) */
        jQuery( ".modal" ).each(function( modals ) {
        var modalId = "#"+$(this).attr("id");
        console.log("--> " + modalId + " - has been appended to body");
        jQuery(modalId).appendTo("body");
        });
    },4000);

	toleranceElement: '> div'
 });
});
//Please note: every <li> must have either one or two direct children, the first one being a container element (such as <div> in the above example), and the (optional) second one being the nested list. The container element has to be set as the 'toleranceElement' in the options, and this, or one of its children, as the 'handle'.

Toggle multiple CSS classes in one statement in VanillaJS

We can't directly execute with .classList multiple classes.

Need write your own "utility" function which does that we want.

<div id="parent" class="c1">aa</div>
<button id="btn">Click</button>

var toggleClassExprFn = function(element, class1, class2) {
  element.classList.toggle(class1);
  element.classList.toggle(class2);
}

var parentDiv = document.getElementById("parent");

// init function
toggleClassExprFn(parentDiv,'class_1', 'class_2');




// Optional bind with button
var btn = document.getElementById("btn");
btn.addEventListener("click", function(){
  //Callback function
  toggleClassExprFn(parentDiv,'class_1', 'class_2');
})

Toggle multiple classes with an array

var parentDiv = document.getElementById("parent");
var classes = [
    "amoos",
    "php",
    "orange"
  ]

  for (var i = 0; i < classes.length; i++){
    parentDiv.classList.toggle(classes[i])
  }

with (...x) Spread Operators ✨

var parentDiv = document.getElementById("parent");

//with (...x) Spread Operators
// NOTE: toggle not work for multiple classes
const multi_classes = ["foo", "bar"];
parentDiv.classList.add(...multi_classes);

How to check if element exists and remove or create it

var findElement = document.getElementById("elementId");
var parentDiv = document.getElementById("parentDivId");

if (document.contains( findElement )) {
    findElement.remove();
} else {
    parentDiv.appendChild( findElement );  
}

if else in a switch / Multi-case with single operation in JavaScript

var box = 'green';
switch (Animal) {
  case 'red':
  case 'white':
    console.log('This animal will go on Noah\'s Ark.');
    break;
  case 'green':
  default:
    console.log(' Its green only do something else.'); 
}

OR

var box = 'green';
switch (true) {
  case (box === 'red' && box === 'white'):
    console.log('Its Red&White.'); 
    break;
  case (foo === 'green'):
    console.log(' Its green only do something else.'); 
    break;
  default:
    // yada yada
}

IE error “SCRIPT1014: invalid character” where all other browsers work

IE not supported "`" (template strings) : http://caniuse.com/#search=string

instead of

	`string text ${expression} string text`
	
	var nameStr = `I'm "Amoos" Jhon`;

write

	"string text "+expression+" string text"
	
	var nameStr = 'I\'m "Amoos" Jhon';

NOTE: Backticks (`) are used to define template literals. Template literals are a new feature in ES6 to make working with strings easier.

Features:

we can interpolate any kind of expression in the template literals. They can be multi-line.

we can easily use single quotes (') and double quotes (") inside the backticks (`).

How to trigger multiple onclick event in JavaScript?

1. Maintainable JavaScript is using a named function. it will make your code a lot easier to read and maintainable.

var el = document.getElementById("myButtonId");

// create named functions:
function alertFirstFn() { alert('hello world'); };


el.addEventListener("click", function(){alert("click1 triggered")}, false);

// assign functions to the event listeners (recommended):
el.addEventListener("click", alertFirstFn );


// then you could remove either one of the functions using:
el.removeEventListener('click', alertFirstFn);

2. Attaching the event handler to the DOM node through your Javascript code.

  onclick="doSomething();doSomethingElse();"

3. All functions link with 1 function defined

  <a href="#" onclick="someFunc()">Click me To fire some functions</a>

// Firing multiple functions from someFunc()
function someFunc() {
    showAlert();
    validate();
    anotherFunction();
    YetAnotherFunction();
}

VanillaJS equivalents of jQuery methods

Selecting elements

// jQuery, select all instances of .box
$(".box");

// VanillaJS Instead, select the first instance of .box
document.querySelector(".box");

// …or select all instances of .box  
document.querySelectorAll(".box");

.hide(

//jQuery Hide all instances of .box
$(".box").hide();


// VanillaJS Iterate over the nodelist of elements to hide all instances of .box
document.querySelectorAll(".box").forEach(box => { box.style.display = "none" }

.prop("checked" | Check a radio button

// jQuery
$("#box").prop("checked", true);
//OR
$( "input#box" ).attr( "checked" ); // Returns ‘true’ if present on the element, returns undefined if not present
//OR
$('input#box').is(':checked');


// VanillaJS
document.getElementById("box").checked = true;

.hasClass(

// jQuery
if ( $(".box").hasClass("selected") ) {

// VanillaJS
  if ( document.querySelector(".box").classList.contains('selected') ) {

.addClass(

// jQuery
$('.box').addClass('thisClass');

// VanillaJS
document.querySelector(".box").classList.add('thisClass');

.removeClass(

// jQuery
$('.box').removeClass('thatClass');

// VanillaJS
document.querySelector(".box").classList.remove('thatClass'); 
  // "Cannot read property 'remove' of undefined"
  // See NOTE for multiple elements

.toggleClass(

// jQuery
$('.box').toggleClass('anotherClass');

// VanillaJS
document.querySelector(".box").classList.toggle('anotherClass');

NOTE: .classList.remove

querySelector to get only the first occurrence, document.getElementsByClassName returns an array-like object of all child elements which have all of the given class names.

  // Or select the first one in the HTMLCollection by it's index like so
  document.getElementsByClassName(".box")[0];

    var element = document.getElementsByClassName('box');
    
    for(var i = 0; i < element.length; i++) {

      element[i].classList.remove('selected');
      console.log(element[i].className);

    }

.find()

// jQuery
$('.box').eq(2).find('.icon').css('background', 'pink')

$('.box').find('.icon')


// VanillaJS
document.querySelectorAll('.box .icon')[2].style.background = 'pink'

document.querySelectorAll('.box .icon')

// jQuery
// Select the first instance of .box within .container
var box = $(".box");
    box.find(".icon");

// VanillaJS
// Select the first instance of .box within .container
var box = document.querySelector(".box");
    box.querySelector(".icon");

.css(

// jQuery
$("#box").css("transform", "scale(1." + zoomValue + ")");


// VanillaJS
var boxElement = document.getElementById('box');
    boxElement.style.transform = "scale(1." + zoomValue + ")";

check OR uncheck a radio button

// jQuery
$(this).prop('checked', false);
  // Note that the pre-jQuery 1.6 idiom was
  // $(this).attr('checked', false);

// VanillaJS
this.checked = false;

.remove()

// jQuery
$('#box').remove();


// VanillaJS
var elem = document.getElementById("box");
elem.remove();

.ready()

// jQuery
$(document).ready(function() {
  // do something
})

// Vanilla
document.addEventListener('DOMContentLoaded', function() {
  // do something
})

//jQuery
var divs = $("div");


//VanillaJS
var divs = document.querySelectorAll("div");

}

Event listening for dynamically added elements

// even when they're added to the DOM programmatically
$(".box-container").on("click", ".box--result", handleClick);

// VanillaJS
// Create and add an element to the DOM
var searchElement = document.createElement("div");
document.querySelector(".box-container").appendChild(searchElement);

How to split a string at a particular character?

JavaScript Prototype String.prototype.split(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split) function:

var input = 'Amoos John~New York~NY~10010';

var fields = input.split('~');

var name = fields[0];
var city = fields[1];

// ES6
var input = 'Amoos John~New York~NY~10010';

var [name, city, state, zip] = input.split('~');

console.log(name); // Amoos Jhon
console.log(city); // New York
console.log(state); // NY
console.log(zip); // 10010

JavaScript running very slow

The reason of slow performance mostly because of loop is so. (for, do while, for in)

Javascript runs in two passes. First sets up variables and functions and then the second run your code.

i.e

element.innerHTML
// OR
element.append("new content");

while(i<input.files.length){
    tmpContent +=input.files[i].name+'<br/>';
    i++;
 }
$("#dataHolder").innerHTML += tmpContent;

NOTE: looked at the performance and memory usage graphs in chrome developer's tools for significant difference.

input type=“number” onchange event not working first time.

Following code covered keyboard input, mousewheel changes and button clicks.

$("input[type=number]").bind('keyup input', function(){
  // handle event
});

Calling function before on click event handler in jQuery JS

Can use onmousedown it's fired before click event.

//jQuery
$("#selector").on("click", function(){
    console.log('click');
});


$("#selector").on("mousedown", function(){
    console.log('mousedown');
});



//Vanilla
document.querySelector('#selector').addEventListener('click', function(){
    console.log('click');
}

document.querySelector('#selector').addEventListener('mousedown', function(){
    console.log('mousedown');
}

Storing and Retrieving data from LocalStorage in JSON format

var boxId = 101;
var boxContent = "XML";
var myObj = [
  {
    name: boxId,
    content: boxContent
  }
];

console.log(myObj);

if (window.localStorage) {
  // converting object to JSON format
  var myObj_serialized = JSON.stringify(myObj);
  console.log(myObj_serialized + " <--JSON Format");

  localStorage.setItem("myObj", myObj_serialized);

  // localStorage data store into variable
  var localListJson = localStorage.getItem("myObj");
  var local_list = localListJson ? JSON.parse(localListJson) : [];

  // Adding new data to LocalStorage
  var new_data = { name: "102", content: "YML" };
  local_list.push(new_data);
  console.log(local_list);
  console.log("^ Open above arrow sign");

  var final_serialized = JSON.stringify(local_list);
  console.log(final_serialized);
}

Open Print Dialog on click event

How to get JSON data from external file in JavaScript?

  function readJsonFile(file, callback) {
    var rawFile = new XMLHttpRequest();
    rawFile.overrideMimeType("application/json");
    rawFile.open("GET", file, true);
    rawFile.onreadystatechange = function() {
      if (rawFile.readyState === 4 && rawFile.status == "200") {
        callback(rawFile.responseText);
      }
    }
      rawFile.send(null);
    }
  
  /* usage */
  readJsonFile("http://localhost/projects-name/my_data.json", function(text){
    var data = JSON.parse(text);
    console.log(data);
  });

NOTE: Use $.get instead of function this if you are getting data from external url.

 $.getJSON("http://localhost/projects-name/my_json", function(text) {

   var PatternData = JSON.parse(JSON.stringify(text));

// 
//readJsonFile("http://localhost/project-name/json/my_data.json", function(text) {

//var PatternData = JSON.parse(text);

      change: function(event, ui) { ui.placeholder.css({visibility: 'visible', border : '1px solid #ccc'}); }
    });
  });

  .ui-sortable-placeholder {
	background-color: #999 !important;
  }
  
  .ui-sortable-helper {
	position: relative;
	top: -28px !important;

Switch active class in group of anchors base on click event.

<div class="row link-group--active">
  <a href="#Link_1">Link 1</a>
  <a href="#Link_2" data-offset='100'>Link 2</a>
  <a href="#Link_3" data-offset="200">Link 3</a>
</div>

Note: See .scrolink for detail of data-offset=

	jQuery(".link-group--active a").on("click", function(){
		jQuery(".link-group--active a").removeClass("active");
		jQuery(this).addClass("active");
	});

Click events firing multiple times in jQuery

Use .unbind() to make sure a click only actions once.

jQuery(".button").unbind().click(function() {
    //write your code..
});

Or try ```.off().on()``

jQuery(".button").off().on( "click", function() {
    //write your code..
	console.log("it's work");
});

Set option 'selected' if url string matches

jQuery( "#button" ).on('click', function(){
	if( active_locLastParent == '' ) {
		console.log("Its not product page, select product");
	}else{
	
		function toTitleCase(str) { // to title case..
			return str.replace(/(?:^|\s)\w/g, function(match) {
				return match.toUpperCase();
			});
		}
		var ProductTitle = toTitleCase(active_locLastParent.replace(/-/g , ' '));
		var SelectedProduct = ProductTitle;
		jQuery('[name="post_select-182"]').val(SelectedProduct);
		jQuery('.select2-selection__rendered').text(SelectedProduct);
	}
});

Lazysizes : lazy loader for images

	<script src="lazysizes.min.js" async=""></script>

Does not need any JS configuration: Add the "lazyload" class on images/iframes tag with a data-src and/or data-srcset attribute. Optionally you can also add a src attribute with a low quality image.

<!-- non-responsive: -->
<img data-src="image.jpg" class="lazyload" />

<!-- responsive example with automatic sizes calculation: -->
<img
    data-sizes="auto"
    data-src="image2.jpg"
    data-srcset="image1.jpg 300w,
    image2.jpg 600w,
    image3.jpg 900w" class="lazyload" />

<!-- retina optimized image: -->
<img data-srcset="responsive-image1.jpg 1x, responsive-image2.jpg 2x" class="lazyload" />

<!-- iframe example -->
<iframe frameborder="0"
	class="lazyload"
    allowfullscreen=""
    data-src="//www.youtube.com/embed/ZfV-aYdU4uE">
</iframe>

lazysizes adds the class lazyloading while the images are loading and the class lazyloaded as soon as the image is loaded. This can be used to add unveil effects:

/* fade image in after load */
.lazyload,
.lazyloading {
	opacity: 0;
}
.lazyloaded {
	opacity: 1;
	transition: opacity 300ms;
}

Theme Color Schemes with Sass Mixin

@mixin theme($name, $color, $bg-color) {
  .#{$name} {
    .element {
      color: $color;
      background: $bg-color;
    }
  }
}

@include theme(theme-banana, yellow, white);

  color: yellow;
  background: white;
}

.theme-blueberry .element {
  color: purple;
  background: black;
}

.theme-cherry .element {
  color: white;

Media Queries in Sass / SCSS

/* Using SCSS variables to store breakpoints */
	/*
	  Tablets 		: 768px / 1024px 
	  iPhoneX 		: 375px / 812px 
	  iPhone 6 Plus : 414px / 736px 
	  iPhone 6 		: 375px / 667px

Input Placeholder Style in SCSS ( Using Mixin )

@mixin optional-at-root($sel) {
  @at-root #{if(not &, $sel, selector-append(&, $sel))} {
    @content;
  }
}

@mixin placeholder {
  @include optional-at-root('::-webkit-input-placeholder') {
    @content;
  }

  @include optional-at-root(':-moz-placeholder') {
    @content;
  }

  @include optional-at-root('::-moz-placeholder') {
    @content;
  }

  @include optional-at-root(':-ms-input-placeholder') {
    @content;
  }
}

// Usage
.your-input-class {

  @include placeholder {
    color: darkblue;
  }

}

CSS Animation property stays after animating

it should fade in and once the animation has completed but it fade out.

Note: for retain style use animation-fill-mode values set by the last keyframe encountered during animation.

.myAnimatedDiv {
  animation: fadeIn 1s ease-in-out 3s;
  animation-fill-mode: forwards;
}

Looping a CSS keyframe animation

.myAnimatedDiv {
  animation: fadeIn 1s ease-in-out 3s;
  animation-iteration-count: infinite;
}

SCSS Loops

@for $i from 1 through 7 {
    .process-box:nth-of-type(#{$i}) {
        
        position: relative;
        opacity: 0;

        animation: Anime#{$i} 1s linear;
        animation-delay: ($i * 1.5)+s;
        animation-fill-mode: forwards; 


        @keyframes Anime#{$i} {

Git / Tortoisegit

Pulling updates from remote git branch, when locally it does not exist.

Fetch all remote branches without merging anything

git fetch

Then create a local branch (new_branch_name) from the remote (origin/new_branch_name) & checkout that branch to switch to it:

git checkout -b new_branch_name origin/new_branch_name

git fetch doesn't fetch all branches

Note: run this command by terminal

git fetch --prune

When push in github, why git didn't ask me to type username and password ?

You can manually unset credential.helper by running below command.

git config --global --unset credential.helper use --global or --local or --system as per your needs.

Then pushing in github will ask for username and password.

If you are on windows one other way to do this is as below but note that it will again save your credentials if you use credential.helper with git.

Go to control panel -> Credential Manager -> Windows Credentials and remove your git credential entry/entries.

Bootstrap4

Open modal using hash in URL in Bootstrap4

$(window.location.hash).modal('show');
    $('li[data-toggle="modal"]').click(function(){
       window.location.hash = $(this).attr('href');
});

Open bootstrap4 tab from inside or outside a tab

jQuery('.tab-link').on('click', function(event) {
    /* Prevent url change */
      event.preventDefault();
    
    /* `this` is the clicked <a> tag */
      var target = jQuery('[data-toggle="tab"][href="' + this.hash + '"]'); 
  
    /*opening tab*/
      target.trigger('click');
  
    /* scrolling into view */
    //  target[0].scrollIntoView(true); 
});

Open specific Tab of bootstrap 4 from hashtag URL or external link

	<a href="home.html#tabId_1">tab 1</a>
	<a href="home.html#tabId_2">tab 2</a>
	<a href="home.html#tabId_3">tab 3</a>

    jQuery(document).ready(function () {
        let selectedTab = window.location.hash;
        jQuery('.nav-link[href="' + selectedTab + '"]' ).trigger('click');
    })

How to disable auto Zoom In on from elements - Safari on iPhone

Make sure you not allow scaling add this on meta tag maximum-scale=1.0, user-scalable=0" as your website is properly designed for a mobile device.

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" />

iOS will still zoom, unless you use 16px on the input without the focus.

@media screen and (-webkit-min-device-pixel-ratio:0) { 
  select:focus,
  textarea:focus,
  input:focus {
    font-size: 16px;
    background: #eee;

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

try npm rebuild node-sass OR npm uninstall gulp --save

Then once that is complete run:

npm install

then:

npm run build

Then npm run production should work.
