jQuery.EAN13.js
jQuery.EAN13.js is a lightweight library available as plain JavaScript and as jQuery plugin for the generation of EAN-13 barcodes.
Usage
###Include Plugin###
Insert the following code into the head section of you page:
JavaScript
<script type="text/javascript" src="jquery-ean13.min.js"></script>jQuery
<script type="text/javascript" src="ean13.min.js"></script>Make sure to include this after the jQuery-library.
Insert Canvas
At the place where you want to insert the barcode insert this code:
<canvas id="ean" width="200" height="100">
Your browser does not support canvas-elements.
</canvas>You may change the dimensions of the element. The barcode will automatically be resized.
Simple barcode
For printing the barcode without any further options use the following code. If you don't provide a check digit (just a 12 digit code) it will be generated for you on the fly.
JavaScript
var element = document.getElementById("ean");
new EAN13(element, "9002236311036");jQuery
$("#ean").EAN13("9002236311036");Options
The library provides some options and callback functions. To use them simply provide a option object as the second argument.
Example
JavaScript
var options = {
number: false,
prefix: false,
onSuccess: function(){
alert("Heeeey!");
}
}
new EAN13(document.getElementById("ean"), "9002236311036", options);jQuery
$("#ean").EAN13("9002236311036", {
number: false,
prefix: false
});List of options

|---|---|---|---|
| number | boolean | true | If true the number is printed underneath the barcode to be readable for humans. |
| prefix | boolean | true | If true the country prefix (to be precise the first digit of it) is printed at the left of the barcode. |
