jquery live change on input
<p>I am trying to disable next input boxes if first input box is not empty using jquery, please check html and js code...</p>

<pre><code>&lt;input name = "mrp" id="mrp" type = "text" /&gt;
&lt;input name = "miw" class="mmw" type = "text" /&gt;
&lt;input name = "maw" class="mmw" type = "text" /&gt;
</code></pre>

<p>js code</p>

<pre><code>$(document).ready(function() {
        $('#mrp').blur(function() {     //i have even tried with live('change')
               var mrp = $(this).val();
               if(mrp != '' || mrp != ' '){
                 $('.mmw').attr("disabled", "disabled");   
               }
               else if(mrp == '' || mrp == ' '){
                   $('.mmw').removeAttr("disabled");
               }
               else{
                  $('.mmw').removeAttr("disabled");
               }
        });
