What's included

Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You'll see something like this:

vue-pattern-input/
├── ...
├── src/
│   └── /component
│       └── pattern-input.vue // core
└── /view
    └── demo.html

Parameter declaration

Commonly used regExp

Quick start

JavaScript

setting: {
  regExp: /^[0\D]*|\D*/g, // Match any character that doesn't belong to the positive integer
  replacement: '',
  val: '223'
}

HTML

<pattern-input class="your-class-name"
               :regExp="setting.regExp"
               :replacement="setting.replacement"
               @input="handleInput"
               @change="handleChange"
               v-model.number="setting.val"></pattern-input>

This setting will make user input positive integer only.

When you want get a Number, remember use v-model.number, and the safe maxlength is 15.

Changelog

v3.0.0

• v3.0.0 provides Vue 3 support. You can still use v2.x for Vue 2.

v2.1.4

• Use immediate watch

v2.1.3

• I'm not sure is it necessary to emit all the input events. Now I only emit input and change events.
• Now, you can bind any native event on input !

  <pattern-input
                 ...
                 @change="onChange"
                 @blur="onBlur"
                 @focus="onFocus"
                 ...etc
                 ...</pattern-input>

• Required:
  • Vue: v2.4.0+, because it use $listeners

Thought

I'm not sure is it necessary to emit all the input events. Now I only emit input and change events.

And I think the RegExp settings is not good enough, it's a bit awkward. Maybe I should match what I want instead of replacing what I don't want. But how ?
