Question

我正在尝试使用java脚本获取浏览器窗口的尺寸。我用来做这个的功能是：

function getDimensions(){
    var myWidth = document.documentElement.clientWidth; 
    var myHeight = document.documentElement.clientHeight; 
    var returnstring = myWidth+','+myHeight;
    document.applets[0].postDimensions(returnstring); 
}

但返回的宽度和高度均为零。我不明白为什么。

下面列出了来源。

<html>
<head>
    <title>Emscribe Dx Review Screen</title>
<style type="text/css">
body {

    text-align: left; /* for IE */
}
#container {

    text-align: left; /* counter the body center */
    /*width: 1250px; */
}

</style>

}

Answer 1

点击link查看javascript。

Here is a great resource to get browser width and height w.r.t different browsers

Answer 2

原始代码是通过Google搜索获得的。众所周知，Google搜索并不总能提供正确的答案。我知道这个html中有过时的代码，但现在不是优先考虑的问题。到目前为止，答案是在另一个网页上找到的。我张贴其他人的好处：

function getDimensions()
{
  var myWidth = document.documentElement.offsetWidth;
  var myHeight = document.documentElement.offsetHeight;
  var returnstring = myWidth+','+myHeight;
  document.applets[0].postDimensions(returnstring);
}

通过javascript获取浏览器的尺寸
