Selector on a variable content with jQuery
<p>I have this code :</p>

<pre><code>jQuery('#btSave').click(function (event) {
    var jqxhr = $.post("Controller/Action", {
        lastName: $("#LastName").val()      
    },
    function (data) {
        //here
    })
});
</code></pre>

<p>I'd like to know if in the "data" variable the id "Mydiv" exist</p>

<p>How can I don this ?</p>

<p>Thanks,</p>
