I want to load content via ajax to my container (#dialog-analogy). But not full page - only one div with id (#get-cats). I dont know, how to get a content of id from ajax page. Thi is draft script:

function FillCats(catid) {
    $.ajax({
        url: "catalogue.php?cat="+catid+"&size=1",
            cache: false,  
            success: function(html){  
                    var getcat = $('#get-cats').html(html); // wrong
            $("#dialog-analogy").html(getcat);
            }  
    });
}

You'll be glad to know that jQuery's load function has exactly the functionality you want. You just append a selector to the end of the URL.

function FillCats(catid) {
    $("#dialog-analogy").load("catalogue.php?cat="+catid+"&size=1 #get-cats");
}

See the Loading Page Fragments section of the load documentation.

If for some reason you can't use load, you can emulate it easily by building up the structure of what you've received via $() and then extracting the element(s) you want:

function FillCats(catid) {
    $.ajax({
        url: "catalogue.php?cat="+catid+"&size=1",
        cache: false,
        success: function(data) {
            $("#dialog-analogy").html($(data).find("#get-cats"));
        }
    });
}
