提问by user1234597

I'm trying to send users to another page when click html body:

单击 html body 时,我试图将用户发送到另一个页面:

JavaScript c.js:

JavaScript c.js:

function clickBody(){
    window.location.href = '/';
}

HTML:

HTML:

<!DOCTYPE html>
<html>
<head>
    <script src="c.js"></script>
</head>

<body onclick="clickBody();">
</body>  
</html>

I can run the function from console, but clicking the <body>is not working.

我可以从控制台运行该功能,但单击<body>不起作用。

The <body>element is empty. You have to either change its height in CSS, or put some text in it.

<body>元素为空。您必须在 CSS 中更改其高度,或者在其中放置一些文本。

Also, using element.addEventListener()might be a good idea. See addEventListener vs onclick.

此外,使用element.addEventListener()可能是一个好主意。请参阅addEventListener 与 onclick

See code snippet:

见代码片段:

function clickBody() {
    window.location.href = '/'
}
document.body.addEventListener("click", clickBody)
<!DOCTYPE html>
<html>
<head>
    <script src="c.js"></script>
</head>

<body>
  <p>Try clicking me.</p>
</body>  
</html>

<body>element have no height, add something like bellow:

<body>元素没有高度,添加如下内容:

<!DOCTYPE html>
<html>
<head>
  <style>
    body {
     height: 500px;
    }
  </style>
  <script src="c.js"></script>
</head>

<body onclick="clickBody();">

</body>  
</html>
