setTimeout() doesn't seem to be working in Firefox?
提问by flyersun
I have inherited a website! which was designed to work in IE and only IE it seems.. I've now been asked to make the site run in Firefox. I've fixed most of the bugs without any problems but this one has me stumped.
我继承了一个网站！它旨在在 IE 中工作，而且似乎只能在 IE 中工作。我现在被要求让该站点在 Firefox 中运行。我已经修复了大部分错误，没有任何问题，但这一个让我难倒。
setTimeout(fDelayedFunc, 1000);
设置超时（fDelayedFunc，1000）；
This line of Javascript, works fine in IE but in Firefox the function fDelayedFunc never fires. I've removed the setTimeout and the function wrapper and tried running the code as part of the main function. This works without any problems at all.
这行 Javascript 在 IE 中运行良好，但在 Firefox 中函数 fDelayedFunc 从不触发。我已经删除了 setTimeout 和函数包装器，并尝试将代码作为主函数的一部分运行。这完全没有任何问题。
There is alot of code involved but here's the main but I'm having trouble with. If you'd like to see anymore of the code please let me know.
涉及很多代码，但这是主要的，但我遇到了麻烦。如果您想查看更多代码，请告诉我。

Try this:
试试这个：
setTimeout(function() { fDelayedFunc(); }, 0);
回答by Ali Tarhini
try this : setTimeout('fDelayedFunc()', 0);
试试这个： setTimeout('fDelayedFunc()', 0);
