Loop Is Too Slow For IE7/8

I have a loop execution that needs to run in all browsers. in chrome/ff etc the execution runs fast and fine. in IE it's slow and end's up dispatching a prompt saying a script is r

Solution 1:

You can use some asynchronous iteration technique instead of loops. Watch Asynchronous Iteration Patterns by Pedro Teixeira for a nice introduction. It uses Node.js but you can use the same patterns in the browser.

Solution 2:

What exactly does the loop do? Is the number of iterations deterministic? If this is something which is causing the browser to hang you may want to consider javascript worker-threads https://developer.mozilla.org/En/Using_web_workers (although I'm not sure which browsers currently support this feature).
