If you are developing application that has quite number of checkbox, you should consider to make a check/uncheck all checkboxes feature to facilitate if users want to choose all the options in effective way rather than click it one by one. Today let’s take a look at how we make it possible to check all options in only one click.

JavaScript Code

Quite simple, we only use single line of code. Look at the highlighted code, we try to find checkboxe inside the id=”checkboxes” and set the attribute of “checked”.

<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
       <script type="text/javascript">
            $(document).ready(function(){
            	 $("#checkall").click(function(){
            	 	   $("#checkboxes").find(":checkbox").attr("checked",this.checked);
            	 });
            })
       </script>

HTML Code

Simple HTML code contains 6 checkboxes and 2 div tags.

<body>
        <div id="box">
    	    Choose your favorite 
    	    <div id="checkboxes">
    	    	<input type="checkbox" value="Java">Java <br>
    	    	<input type="checkbox" value="PHP">PHP <br>
    	    	<input type="checkbox" value="JavaScript">JavaScript <br>
    	    	<input type="checkbox" value="HTML">HTML <br>
    	    	<input type="checkbox" value="CSS">CSS <br>
    	    	<hr>
    	    	<input type="checkbox" id="checkall" >Check/Uncheck All <br>
    	    </div>
        </div>
  </body>

CSS Code

Our css file for better view.

<style type="text/css">
            #box{
              width:500px;
              background:#96A8E0;
              padding:10px;
              border:solid #4968CC;
              margin:0 auto;
            }

            input{
              margin-right: 10px;
            }
      </style>
