I know you can use the window.onload event to make functions run, but is there a way for a script to query if the document is ready or not?
我知道您可以使用 window.onload 事件来运行函数，但是有没有办法让脚本查询文档是否准备就绪？
Something like
就像是
function update()
{
if( !document.ready() ) // don't do unless document loaded
return ;
}
window.setInterval( 'update();', 100 ) ;
Cannot change the <body> element, and no jQuery/other libraries.
不能更改 <body> 元素，也不能更改 jQuery/其他库。

Here you go:
干得好：
var tid = setInterval( function () {
if ( document.readyState !== 'complete' ) return;
clearInterval( tid );
// do your work
}, 100 );
Read about the document.readyStateproperty here. I am not sure if all current browsers implement it.

It's more complicated than a few lines! - If you want multiple browser compliance.
比几行还复杂！- 如果您想要多个浏览器合规性。

This code will work in all browsers
此代码适用于所有浏览器
if(window.attachEvent()){
window.attachEvent("onload",load);
}else{
window.addEventListener("load",load,true);
}
function load(){
//Code to execute when the document is loaded.
}
