big Ajax problem .. can't figure it out
<p>Hy, </p>

<p>I have a live username validation using ajax :</p>

<pre><code>&lt;td id="user_process_live"&gt;&lt;input type="text" id="user_live_ver" name="user" /&gt;&lt;/td&gt;
</code></pre>

<p>abnd the following java :</p>

<pre><code>  $("input#user_live_ver").blur(function() {
    var username=$(this).val();
    var dataString = 'username=' + username;
    $.ajax({
        type: "POST",
        url: "ajax/login_ajax.php",
        data: dataString,
        cache: false,
        success: function(html) {
           $("td#user_process_live").html(html); 
        }

        });
    });
</code></pre>

<p>The <code>login_ajax.php</code> returns the same <code>&lt;input type=text id=user_live_ver name=user /&gt;</code> but with different styles applied (background-color and border-color) : red if username already exist and green if user does not exist ...</p>

<p>The problem is the script does this just one time .. just one <code>.blur()</code> ... </p>

<p>If i remove the <code>.ajax({ ... etc });</code> and insert <code>alert(dataString);</code> every time i click out that input the <code>alert()</code> is triggered but not the same for the <code>.ajax()</code> ...</p>

<p>What seems to be the problem ? Thanks a lot</p>
