Is there any way to time how long a jquery ajax request has been going on? sometimes searches take too long and it would be nice to add a jquery abort() button if the search takes over, say, 5 seconds. Any way I can do this!

On the other end of the ajax request is a php file that makes a postgresql request.

Much thanks for any ideas!

here is how you can timeout ajax request if it doesn't respond in stipulated time period:-

$.ajax({
    url: "yourphpurl",
    type: "GET",
    dataType: "json",
    timeout: 5000, //5 secs time out
    success: function(response) { alert(response); },
    error: function(x, t, m) {
        if(t==="timeout") {
            alert("timed out");
        } else {
            alert(t);
        }
    }
});¿

The returned object from $.ajax is an XMLHttpRequest object. This object has an "abort" method. Call this method to cancel the request.

So you could do something like this:

(function(){
  var xhr;
  $('#foo').bind('click', function() {
    if(xhr)
    {
      xhr.abort();
      xhr = null;
      $(this).text("Search");
    }
    else
    {
        $(this).text("Cancel");
        xhr = $.ajax({blah blah blah, your request params...});
    }
  });
})();
