Is there an equivalent to the php die() function for javascript that stops all javascript (including future callbacks for ajax requests, timeouts etc...) from running?
(NOTE: I can't use breakpoints in the debugger as the bug is in ie8 and the debugger prevents you from scrolling up/down the page while at a breakpoint; to be able to see at which point the bug is occurring I need to be able to scroll the page while the code is stopped)

No.
That's all there is to say, really.
回答2:
Yes, it can be done. This will end execution of the javascript.
throw new Error('');
回答3:
debugger;
in console to pause execution (at least in chrome)
