问题
My website makes a lot of requests. I often need to cancel all current requests, so that the browser is not blocking relevant new requests.
I have 3 kinds of requests:
- Ajax
- inserted script-tags (which do JSONP-Communication)
- inserted image-tags (which cause the browser to request data from various servers)
For Ajax its no problem as the XMLHttpRequest object supports canceling. What I need is a way to make any browser stop loading resources, from DOM-Objects.
Looks like simply removing an object (eg. an image-tag) from the DOM only helps avoiding an request, if the request is not already running.
UPDATE: a way to cancel all requests, which are irrelevant, instead of really any request would be perfect.
回答1:
window.stop() should cancel any pending image or script requests.
回答2:
I think document.close() stops all requests, but I'm not so sure about it.
