Question

On my website I have mouse over and mouse out events set up on an HTML table. These events trigger ajax requests, and perform certain actions etc. However, i want to be able to not trigger a second request if one is already running. So, is there away to detect these requests, and therefore avoid a second. Incidentally Im using the jQuery $.ajax()
if it helps at all.

Thanks in advance

I’d try something simple like:

var requestMade = false;

function yourAjaxFunction(){
    if(!requestMade)
    {
        requestmade = true;
        $.ajax({
            url: "page",
            success: function(){
                requestMade = false;
            }
            error: function(){
                requestMade = false;
            }
        });
    }
}

You can use the success: and error: settings to change the variable back to false.

I have never used the error so you may have to include some other things in it, but this is the general idea.
