在页面加载后执行的JavaScript [英] JavaScript that executes after page load
问题描述
我在< head> 中使用< script> 执行外部脚本。
I'm executing an external script, using a <script> inside <head>.
现在，脚本在之前执行页面已加载，因此我无法访问< body> 等等。我想在文档加载（HTML完全下载和内存）后执行一些JavaScript。是否有任何事件可以在我的脚本执行时挂钩，并在页面加载时触发？
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?
推荐答案
这些解决方案将work：
These solutions will work:
<body onload="script();">
或
document.onload = function ...
甚至是
or even
window.onload = function ...
请注意，最后一个选项是更好的方法，因为它是 unobstrusive 和是认为更标准。
Note that the last option is a better way to go since it is unobstrusive and is considered more standard.
