Asynchronous searching with AJAX and Jquery

I have a page I'm building which is powered primarily with AJAX. I want the searching on the page to be asynchronous so that as the user types, the search results change on the fly. I was able to make this work somewhat by sending an AJAX call on keyup from the text box, and it works well in Chrome, FF, etc. The only problem I'm having is in IE开发者_运维问答7. The page starts to get really slow as you type, so I'm assuming that perhaps the function to call the AJAX is being opened several times without being closed, causing the page to get slow. Is there an easy way to do this where I can basically end the current AJAX call if another key is pressed? Or is there maybe some other reason that IE could be slow? The general code is:

$('.search_input').keyup(function(e) { make ajax call and populate results }

Thanks in advance for your help.

Hmm...I have something just like this and I tested it out in IE7 without receiving any slowdowns. Here's what my code looks like:

$("#key").keyup(function(event) {
        if(event.which != '13') {
            $.get("hash.php", {key: $("#key").val()}, function(hashes) {
                $("#hashvalues").html(hashes);
            });
        }
    });

"#key" is a text input field, "hash.php" is the current page, and "#hashvalues" is the main container div on the hash.php page.

Are you returning an insane amount of data for any reason? I've seen IE slow way down if there's a LOT of HTML returned.

Use jQuery.Load() to keep loading a seperate page into a placeholder element (div for example), and pass the value of 'search_input' as a querystring value each time.

This will give that new Google search feel, if thats something youre after
