Inject part of document, using jQuery-UI tabs

Question

Hello, I'm using jQuery-UI tabs, to load internal/external (on-site) content.

Is it possible to load part of the document, as it is possible with standart $.ajax, without rewriting complete code?

$.ajax({
  url: passedUrl + " #pageContent .mySelector",
  cache: false,
  success: function(html){
    $("#loadHere").append(html);
  }
});

Thanks in advance!
