Hello,

I'm trying to return the value in the success (data) part of my $ajax call. I've looked through Google but what I'm looking for is a coded solution below. I don't think it's that complex from similar examples I've seen. I just can't seem to get mine working.

When I add alert(data); I get...

<wddxPacket version='1.0'><header/><data><string>1</string></data></wddxPacket>


but I would like to be able to run 2 different functions if <string> eq "1" or "". Is that possible?
 	$.ajax({
		type: "POST",
		url: "app/func_main.cfc?method=login",
               data: data,
		cache: false,
		success: function (data) {

			alert(data);

                      if (data.string == 1) {
                           function1();
                     } else {
                          function2();
                     }

 		},
 		error: function (xhr, ajaxOptions, thrownError) {
        alert(xhr.status);
        alert(thrownError);
      	}

	});

It looks like you need to add the data type to your ajax call, then 'data' in the callback will be an xml document and you can use the following code to determine which function to call:
    $.ajax({
        type: "POST",
        url: "app/func_main.cfc?method=login",
        data: data,
        dataType: 'xml',
        cache: false,
        success: function (data) {

            //alert(data);

            try {
                // use jQuery functionality to read xml to avoid browser specific code
                var str = $($.find('data > string', data)[0]).text();

                if (Number(str) === 1) {
                    function1();
                } else {
                    function2();
                }

            } catch (e) {
                alert('error while parsing xml: ' + e.message);
            }

        },
        error: function (xhr, ajaxOptions, thrownError) {
            alert(xhr.status);
            alert(thrownError);
        }

    });

check this : http://jsfiddle.net/vB6V9/
alert(data);

var str = $("string",data).text() * 1;
if (str == 1) {
    function1();
} else {
    function2();
}

In your question you indicate that you want to check against a string value of 1 - "1", not a number. If that's the case then this in the success handler:

$string = $('string', data).text();
if ($string == '1') {
   function1();
} else {
   function2();
}

Thanks for the help everybody! I tried them all but  leakim971's solution was the only one I got to work. Maybe I missed something on the others but it's exactly what I needed. Thanks!
