The maximum browser size width would be the width and height of the screen:
最大浏览器大小宽度将是屏幕的宽度和高度：
screen.height;
screen.width;
But I'd use CSS media queries for what you're trying to do:
但是我会使用 CSS 媒体查询来处理您要执行的操作：

Something like this would make the page background black if the window is less than 500px wide:
如果窗口宽度小于 500px，这样的事情会使页面背景变黑：
@media only screen and (max-width: 500px) {
body {
background: #000;
}
}
Update:
更新：
Oh, and you'll want a polyfill for older browsers that don't support media queries:
哦，对于不支持媒体查询的旧浏览器，您需要一个 polyfill：

That'll get you media queries all the way down through IE6!
这将使您通过 IE6 一直进行媒体查询！

If you can use jQuery, it's pretty easy to set up a listener in a cross-browser fashion:
如果您可以使用 jQuery，那么以跨浏览器的方式设置侦听器非常容易：
$(window).resize(function() {
alert($(window).width()) //window width
alert($(window).height()) //window height
}).trigger("resize") //to ensure that you do whatever you're going to do when the window is first loaded;
