javascript verify the result of ajax request in a function

So i've been struggling with this issue for a while... I want to verify the result of an ajax request in a function. I know that the ajax call doesn't end when the function ends, but I don't know how to make the above sample piece of code work.

function verify(data)
{
  if(data > 5)
     return false;
  else
  {
     // ajax call
     if(ajax response == "")
       return  false;
  }
}

You need to specify verify as the callback for your ajax call.

If you're using jQuery, it would look something like:

$.ajax('foo.asmx/Method',  { dataType: 'json', success: verify });

If you'd like to use jQuery to set up a global ajax handler for any call, you can use the ajaxSuccess function.

If you're doing this natively, with an actual xhr object, I think you need something like this:

xhr.onreadystatechange = function() {
    if (xhr.readyState === 4) {
        verify(xhr.responseText);
    }
}
