Exactly. Sounds like a flaw in IE 9 that they're trying to pass off as an error on the webpage. If the API / functionality exists it should work and not give you a chance of killing the browser.
- olavk 15y agoSync XHR should hang the page while waiting for the response. It should not hang the whole browser, but it should pause rendering and event processing on the page - i.e. cause the page to be unresponsive. Otherwise it wouldn't be synchronous. A different issue is whether the synchronous mode of XHR was a good idea in the first place. But what's done is done.
- nkassis 15y agoIt's not a flaw in IE it's the same in all browsers they use one thread for javascript and UI updates. IE10 will have Web Workers which can be used to prevent this but using Web Workers still involves programmers making their code work async which is the point of this post.
