javascript jsonp内存泄漏

Question

I'm seeing the same problem described in Memory Leak When Pulling JSON from WEB.

I simply have a function that makes a jsonp ajax request periodically. My function is called by another function triggered by a setInterval.

I see a memory leak in all broswers that I've tried, IE, Safari, FireFox. Something I see in the Safari script debugger is that each response to an ajax request is listed as a script in the drop down list in the script debugger window, as if there is some kind of script object not getting cleaned up.

I'm using jquery 1.6.2. It is a "long term" leak, not cleaned up after running for several minutes.

Any ideas what is causing this?

    request: function ()
    {
        $.ajax({
            url: <myurl>
            dataType: "jsonp",
            jsonp: "jsoncallback",
            timeout: 5000,
            cache: false,

            beforeSend: function (xhr)
            {
            },

            success: function (data, status, xhr)
            {
            },

            error: function (xhr, status, error)
            {
            },

            complete: function (req, status)
            {
            }
        });
    }
    ...
    setInterval(request, 100);

Answer 1

The fact you're sending ajax request every 100 milliseconds is enough.

Be aware, setInterval(request, 100); - 100 does not mean seconds, but milliseconds. 1 second = 1000 miliseconds
