Question

I have some pages that i acces by jquery $.post like this:

$.post(url, {name: name}, function(data)
{
    var htmldata = $(data);
    if($('#ok', htmldata).val() == "1")
    {
        //some things carried out
    }
});

$('#ok', htmldata).val() is allways undefined so where is the problem?

UPDATE: htmldata = <input id=\"ok\" type=\"hidden\" value=\"1\" /> and another 2-3 hidden input.

Answer 1

$('#ok', htmldata) will look for all descendants of htmldata that have the id of ok.

You need to change $('#ok', htmldata) to htmldata.filter('#ok')
