Pause javascript execution while waiting on response

Question

I'm looking for a way to pause a javascript function while waiting for the user to make a choice. I would like it to work like prompt, alert or confirm (they pause the script) but I would like to create my own query box in html.

Is there any way that I can achieve this?

Setup a callback that will be called when the user make the choice then let the javascript end after showing the choices to the user.

Thanks a lot! Do you know any good tutorial that shows how to write a good callback function?

this is an example w3schools.com/js/tryit.asp?filename=tryjs_events taken from here w3schools.com/js/js_examples.asp which is a nice site

But does a callback really pause the execution of the javascript code?

No, it doesn't. Nothing pauses a JavaScript thread - there's no sleep function. What the callback does is that it waits for a specific action to finish before commencing executing on the code within the callback

Paolo Over a year ago

the javascript thread pauses when ends. but the javascript engine keeps running if there are callback that may be triggered by events.
