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？

>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?
These solutions will work:
<body onload="script();">
or
document.onload = function ...
or even
window.onload = function ...
