javascript - 如何在加载页面时运行函数?(How to run a function when the page is loaded?)

I want to run a function when the page is loaded, but I don't want to use it in the <body> tag.

(我想在页面加载时运行一个函数,但我不想在<body>标签中使用它。)

I have a script that runs if I initialise it in the <body> , like this:

(如果我在<body>初始化它,我会运行一个脚本,如下所示:)

function codeAddress() {
  // code
}
<body onLoad="codeAddress()">

But I want to run it without the <body onload="codeAddress()"> and I have tried a lot of things, eg this:

(但是我想在没有<body onload="codeAddress()">情况下运行它,我尝试了很多东西,例如:)

window.onload = codeAddress;

But it is not working.

(但它没有用。)

So how do I run it when the page is loaded?

(那么如何在加载页面时运行它?)
