I need to run a super long JavaScript on my page. The client is complaining that IE shows a warning dialog for the script being too long. Unfortunately, there is no way we can reduce the length of the script, so I am trying to find a bypass for the problem.

According to Microsoft support website:

IE tracks the total number of executed
script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler. It displays a
“long-running script” dialog box when
that value is over a threshold amount.

However I have tried to use both setInterval() and setTimeout() to break my script into pieces, but none is working. The browser I am using is IE8. My code is as following:

<html>
<head>
    <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.min.js"></script>
</head>
<body>
    <div id ="test"></div>
    <div id ="log"></div>
</body>
<script>
    var repeat =0;

    function heavyTask(){
        if (repeat<50){
            y = longRun();
            setTimeout("heavyTask()",100);
        }else{
            $('#test').html("done!");
        }
    }
    function longRun(){
        for(var i =0; i<20000;i++){ }
        repeat++;
        $('#log').append('<div>repeat: '+ repeat +'</div>');
    };

    $(document).ready(function () {
        setTimeout("heavyTask()",100);
    });
</script></html>

In order to make the code work, you have to edit Registry, go to
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles, and set the DWORD value called “MaxScriptStatements” to 100,000. If the Styles key is not present, create a new key that is called Styles.

Thanks,
