避免坏< SCRIPT SRC =>挂着页面 [英] Avoiding bad <SCRIPT SRC=> hanging the page
问题描述
我的HTML页面有< SCRIPT SRC = http：// remote / script>在每页的顶部''$
。有时远程主机（可能由于负载过重或网络连接不稳定）并没有长时间响应。这个
导致整个页面显示挂起而没有任何加载。
是否有一些技巧我可以使用settimeout（）以便如果远程
页面/浏览器取消加载那个脚本吗？

对于IE，如果脚本没有生成页面内容（例如不使用
document.write）尝试
< script defer type =" text / javascript"
src =" http://example.com/file.js">< / script>

不仅仅是IE。 推迟属性在HTML 4中指定。

可悲的是，脚本执行document.write（...）（因为我猜大多数其他的
有趣脚本没有。
有没有办法可以做这样的事情：
< script>
如果（不能在15秒内ping /连接到远程主机的端口80）{
//跳过
}否则{
document.write（''< script src = http：// remote-host / script>< / script>''）;
}
}
< / script>

My HTML pages have a <SCRIPT SRC=http://remote/script> at the top''ish
of each page. Sometimes the remote host (probably due to heavy load or
flaky network connectivity) doesn''t respond for a long time. This
causes the whole page to appear hanging without anything loading.
Is there some trick I can use with settimeout() so that if the remote
script cannot be loaded after, say, 30 seconds, then I can tell the
page/browser to cancel loading that script?

For IE if the script doesn''t generate page content (e.g. doesn''t use
document.write) try
<script defer type="text/javascript"
src="http://example.com/file.js"></script>

Not just IE. The "defer" attribute is specified in HTML 4.

Sadly, the script does document.write(...) (as I guess most other
interesting scripts do).
Is there a way I can do something like this:
<script>
if (can''t ping/connect to port 80 of remote-host in 15 seconds) {
// skip
} else {
document.write(''<script src=http://remote-host/script></script>'');
}
}
</script>
