jQuery validate and web services
<p>I am using Jörn Zaefferer's jQuery Validate plugin, but I seem to be having issues when I try to call web services using jQuery on the same page.  Instead of making a normal call to a web service:</p>

<pre><code>http://localhost/Services/CDServices.asmx/GetAllUserProfiles
</code></pre>

<p>It does this:</p>

<pre><code>http://localhost/Services/CDServices.asmx/GetAllUserProfiles?callback=jQuery15109683126045224081_1302011466636
</code></pre>

<p>Is there any way to prevent this?</p>

<p>This is the code that initiates the call:</p>

<pre><code>$.ajax(
{
    type: "POST",
    url: "/Services/CDServices.asmx/CheckForUniqueUserName",
    data: ({ strUserName: $('input[name="txtUserName"]').val() }),
    async: false,
    dataType: "json",
    success: function(msg) {
        if (msg.d == 0) {
            alert("Already exists");
        }
        else {
            alert("Username is unique");
        }
    }
});
</code></pre>
