title: How can the JQuery bind() plugin help me
body: <p>I am new to JQuery<br/>
  I am writing a simple data validation using JQuery.<br/></p>
  
  <p>Here is the HTML part:<br/></p>
  
  <pre><code>&lt;input type="text" id="testing"&gt;
  </code></pre>
  
  <p>This is the JQuery part:<br/></p>
  
  <pre><code>$(document).ready(function(){ 
     $("#testing").click(function(){
       // doing something;
        });
  
  $("#testing").change(function(){
        // doing something;
        });
  
  $("#testing").mouseover(function(){
        // doing something;
        });
  });
  </code></pre>
  
  <p>$("#testing") repeated three times in my sample code, is it possible to simplify this?<br/>
  I am not sure if bind() can help solve the question.</p>
