Setting Priority

Does Anyone have experience with setting priorities in javascript

[trifi]

I believe it is possible to set priorities for a function in javascript, does anyone have any experience with this. Before I dive into playing with the concept I wanted to know how browsers respond to this, because the whole concept doesn't seem to reliable to me since you cannot access the client's machine; the browser retains this info.

Not quite sure I understand what you're talking about...
Set priorities for what? One function having a higher priority than another?
There's not multitasking in JavaScript, but everything is run in the order it is called.

Maybe a more concrete description can help me understand what you're getting at...

sorry about being unclear...I have read that you can set Priorities to functions. Also I know there are javascript keywords like getPriority which will return you a value ranging from 1 (highest) to 5 (lowest). I wish I could put the link to an article here but if you type "javascript API Reference setPriority" it should come up. Is this true or am I just not understanding the meaning?

Ok, now that makes a lot more sense... But it's unrelated to the normal JavaScript use on a traditional Web page.

JavaScript is in itself incapable of multitasking. A running process/function has top priority for as long as it runs. Only one JavaScript process can run at a time.

So you can not setPriority to a function. For instance if I were to do a setTimeOut Loop with many objects from an array passing through the loop(numerous times until the opacity of each object was 0 coming down from 100) could I setPriority to this function. I do not want the function to return to where it was called until the opacity is 0.

You don't need "setPriority" to do that. You can just write your JavaScript function that way.
