I am using the jQuery $.ajax() function. I have put this into a parent function, which passes some values into the ajax function. What I would like to do, is have a user defined callback function, which gets the data param passed in from the ajax success function.

Here is what I was thinking would work, but it is not:

```
testFunc = function(str, callback) {
    // Send our params
    var data = 'some data to send';
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: data,
        success: callback
    });
}

```

Then I want to be able to call that function, and pass in my custom function so that I can use the success functions data from inside that function:

```
testFunc('my string data', function(data){
    alert(data);
});

```

I am wanting this to be the same as:

```
testFunc = function(str, callback) {
    // Send our params
    var data = 'some data to send';
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: data,
        success: function(data) {
            alert(data);
        }
    });
}

```
