Javascript:检测窗口何时完全加载 [英] Javascript: Detect when a window is fully loaded

问题描述

我有一个脚本，可以在网页生命周期的任何阶段加载该脚本. 加载脚本后，必须运行initialize()方法.

I have a script which may be loaded at any stage of the life cycle of a web page. When the script is loaded it must run an initialize() method.

我希望此函数在"onload"事件上运行，但不能确定页面尚未加载，即"onload"尚未触发.

I want this function to be run on the "onload" event, but I cannot be certain that the page has not already loaded, i.e. that the "onload" has not been fired already.

理想情况下，我的脚本如下所示:

Ideally my script would look like this:

var _initialize = function() { ...};

if(window.LOADED)
    _initialize();
else if (window.addEventListener)
    window.addEventListener('load', _initialize, false); 
else if (window.attachEvent)
    window.attachEvent('onload', _initialize);

是否有这样的window.LOADED或document.LOADED变量或类似的东西?

Is there any such window.LOADED or document.LOADED variable or something similar?

预先感谢， 肖恩

推荐答案

您可以使用jQuery来做到这一点. $(document).ready().检查此

You can use jQuery to do this. $(document).ready(). Check this

只需在ready中调用所需的函数即可.文档完全加载后，便会执行

Just call the function you want inside the ready. Then it'll be executed once the document is fully loaded
