问题描述
我想在页面加载时运行一个函数,但我不想在 标签中使用它.
I want to run a function when the page is loaded, but I don’t want to use it in the <body>
tag.
如果我在 <body>
中初始化它,我有一个脚本会运行,如下所示:
I have a script that runs if I initialise it in the <body>
, like this:
function codeAddress() {
// code
}
<body onLoad="codeAddress()">
但我想在没有 <body onload="codeAddress()">
的情况下运行它,我尝试了很多东西,例如这个:
But I want to run it without the <body onload="codeAddress()">
and I have tried a lot of things, e.g. this:
window.onload = codeAddress;
但它不起作用.
那么如何在页面加载时运行它?
So how do I run it when the page is loaded?
推荐答案
window.onload = codeAddress;
应该可以工作 - 这是一个演示,以及完整的代码:
window.onload = codeAddress;
should work - here's a demo, and the full code:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
function codeAddress() {
alert('ok');
}
window.onload = codeAddress;
</script>
</head>
<body>
</body>
</html>
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
function codeAddress() {
alert('ok');
}
</script>
</head>
<body onload="codeAddress();">
