Generates barcode 39 labels in browser.

Once you have barcode.js included on your page, call barcode.create to generate your barcode:

var code = barcode.create('HELLO WORLD');

Valid letters are 0-9, A-Z, +, -, $, %, ., /, and (space). barcode.create throws an error if an invalid letter is entered.

Note: lowercase letters, which are not allowed by the barcode 39, will be converted to uppercase.

Once you have your barcode, you can either add it to the DOM with #appendTo or get its source data with #src():

code.appendTo(document.querySelector('body'));

// or

code.appendTo($('body')); // Works with jQuery!

// or

var src = code.src();

Barcode.js should with with all browsers that support canvas, so:

• IE 9+ (further support can be added using explorercanvas)
• Firefox 3.6+
• Chrome
• Safari 3.1+
• Opera 9.0+
• iOS Safari 3.2+
• Android 2.1+
