HTML DOM width + height of visible window
提问by Ian Vink
How do I get the current height and width of the available space in the browser as it is open.
如何在浏览器打开时获取可用空间的当前高度和宽度。
I don't want the height of the total document, just what's visible on the screen.
我不想要整个文档的高度，只想要屏幕上可见的高度。

You can take a look at this blog postto see the method.
您可以查看此博客文章以了解该方法。
and in short in give that code
简而言之，给出那个代码
function alertSize() {
var myWidth = 0, myHeight = 0;
if(typeof(window.innerWidth) == 'number') {
// Non-IE
myWidth = window.innerWidth;
myHeight = window.innerHeight;
}
else if(document.documentElement && (document.documentElement.clientWidth || document.documentElement.clientHeight)) {
// IE 6+ in 'standards compliant mode'
myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
}
else if(document.body && (document.body.clientWidth || document.body.clientHeight)) {
// IE 4 compatible
myWidth = document.body.clientWidth;
myHeight = document.body.clientHeight;
}
window.alert( 'Width = ' + myWidth );
window.alert( 'Height = ' + myHeight );
}
also have to be noted that most of js framework (jquery, ext, prototype) would provide a function for doing that (IMHO).
还必须注意的是，大多数 js 框架（jquery、ext、prototype）都会提供这样做的功能（恕我直言）。
in jQuery:
在 jQuery 中：
$(window).width();
$(window).height();

Use the window objects property, inner height/width, to find the dimensions of just the content on the webpage. This includes the scroll bars. Here is a visual explanation -> http://goo.gl/L0cBLA.
使用窗口对象属性（内部高度/宽度）来查找网页上内容的尺寸。这包括滚动条。这是一个直观的解释 - > http://goo.gl/L0cBLA。
