我正在使用< head> 内的< script> 执行外部脚本。 / p>

现在，由于脚本在页面加载之前执行，因此我无法访问< body> 等。在文档加载后（HTML已完全下载并在RAM中），我想执行一些JavaScript。在脚本执行时，是否有任何事件可以挂接到页面上？

解决方案

这些解决方案将工作：

< body onload = script（）;>

或

document.onload =函数...

甚至

window.onload =函数...

请注意，最后一种选择是更好的选择，因为它是，并且考虑了更多标准。

I'm executing an external script, using a <script> inside <head>.

Now since the script executes before the page has loaded, I can't access the <body>, among other things. I'd like to execute some JavaScript after the document has been "loaded" (HTML fully downloaded and in-RAM). Are there any events that I can hook onto when my script executes, that will get triggered on page load?

解决方案

These solutions will work:

document.onload = function ...

or even

window.onload = function ...

Note that the last option is a better way to go since it is unobstrusive and is considered more standard.
