[jQuery] HTML Partial Element Does Not Exist?!

[jQuery] HTML Partial Element Does Not Exist?!


I have an HTML partial coming back from a server that includes a named
div (ex: <div id="MyDiv">blah</div>)
When I try to run the following on it, it shows the div as empty:
alert($("#MyDiv").html());
I suspect the DOM is not aware of the retuned div (though, why it
displays is then a huge mystery).
Can anyone clarify this for me? Maybe tell me how to tap the DOM on
the shoulder with the newly returned div?
Thanks much!
