Navigate with location.href during XMLHttpRequest asynchronous call
I have a web page containing something like this:
<div onclick="location.href = 'AnotherPage';">

This page also uses asynchronous XMLHttpRequests for some ajax updating.
I have found that while an asynchronous XMLHttpRequest is in progress, clicking on this div does not load the new page. If I cancel my request first then it works fine. This seems wrong, but I cannot find any documentation that describes what should happen.
So the question is: what should happen to asynchronous XMLHttpRequests in progress when a new page is loaded using location.href?
edit - I worked around this problem by handling window.onbeforeunload and aborting my pending async request there. The question remains though, whether I should need to do this?
You might check out a similar question:
Browser waits for ajax call to complete even after abort has been called (jQuery)
I also saw a few questions where browser history issues were arising in similar circumstances, and the workaround was to wrap the location change in a setTimeout()
call with 0
delay. If that were to fix the behavior, I'd be baffled as to the reasoning, but it'd be interesting to see the effect nevertheless.
