Custom Pin Code Input Plugin with jQuery and Bootstrap

Pincode Input is a jQuery plugin that turns the regular text field into a Bootstrap-styled pin code input as you seen in the SIM card PIN management.

Licensed under the Apache-2.0.

Features:

• Auto jumps to next slot.
• Executes a callback after all inputs are filled in.
• Supports unlimited amount of digits.

Basic usage:

1. Include the needed jQuery library and Bootstrap's CSS on the webpage.

<link href="/path/to/bootstrap.min.css" rel="stylesheet">
<script src="/path/to/jquery.min.js"></script>

2. Download and include the Bootstrap Pincode Input plugin's JS and files in the webpage.

<link href="bootstrap-pincode-input.css" rel="stylesheet">
<script src="bootstrap-pincode-input.js"></script>

3. Create a text field for the pin code input.

<input type="text" id="demo">

4. Initialize the plugin.

$('#demo').pincodeInput();

5. Plugin's default options.

$('#demo').pincodeInput({

  // 4 input boxes = code of 4 digits long
  inputs:4,        

  // hide digits like password input             
  hideDigits:true,   

  // keyDown callback             
  keydown : function(e){},

  // callback on every input on change (keyup event)
  change: function(input,value,inputnumber){    
    //input = the input textbox DOM element
    //value = the value entered by user (or removed)
    //inputnumber = the position of the input box (in touch mode we only have 1 big input box, so always 1 is returned here)
  },

  // callback when all inputs are filled in (keyup event)
  complete : function(value, e, errorElement){
    // value = the entered code
    // e = last keyup event
    // errorElement = error span next to to this, fill with html 
    // e.g. : $(errorElement).html("Code not correct");
  }
  
});
