Get the size of the screen

I started to have a problem, I want to do a pop-up div layer, and then set the Z-index properties and height and width background color, etc.
I'm using $ (document). Height (), $ (document). Width () to get the height and width of the window, but when you double-click the browser to change the size of the window, this height does not change ...

The code is as follows Copy Code

CSS Code

<style type= "Text/css" >
#cover {
width:100%;
Background-color: #CCCCCC;
z-index:99;
Display:none;
}
</style>


HTML Code

<body>
<input type= "button" id= "BTN" value= "Show"/>
<div id= "Cover" ></div>
</body>


JScript Code


var btn = $ ("#btn");
var show = $ ("#cover");
Btn.click (function () {
Show.css ({"position": "Absolute", "Top": "0", "Left": "0"});
Show.height ($ (document). Height ());
Show.show ();
});
</script>

Then Baidu found some about jquery get the width and height code of the browser screen

The code is as follows Copy Code


$ (document). Ready (function () {
Alert ($ (window). Height ()); Browser current window visual area height
Alert ($ (document). Height ()); The height of the browser's current window document
Alert ($ (document.body). Height ());//browser Current window document body level
Alert ($ (document.body). Outerheight (True))//Browser Current window document body's total height includes border padding margin
Alert ($ (window). width ()); Browser current window visual area width
Alert ($ (document). width ());//browser Current window Document object widths
Alert ($ (document.body). width ());//browser Current window document body widths
Alert ($ (document.body). Outerwidth (True))//Browser The total width of the body of the current window document includes border padding margin
})

Gets the height width of the current screen

The code is as follows Copy Code


<script type= "Text/javascript" >
$ (document). Ready (function ()
{
Alert ($ (window). Height ()); Browser current window visual area height
Alert ($ (document). Height ()); The height of the browser's current window document
Alert ($ (document.body). Height ());//browser Current window document body level
Alert ($ (document.body). Outerheight (True))//Browser Current window document body's total height includes border padding margin
Alert ($ (window). width ()); Browser current window visual area width
Alert ($ (document). width ());//browser Current window Document object widths
Alert ($ (document.body). width ());//browser Current window document body height
Alert ($ (document.body). Outerwidth (True))//Browser The total width of the body of the current window document includes border padding margin
}
)
</script>


Browser compatibility used, so on the internet to find some of the summary.

The code is as follows Copy Code

var xscroll, Yscroll;

if (window.innerheight && window.scrollmaxy) {

Xscroll = window.innerwidth + Window.scrollmaxx;

Yscroll = Window.innerheight + window.scrollmaxy;

} else {

if (Document.body.scrollHeight > Document.body.offsetHeight) {//all but Explorer Mac

Xscroll = Document.body.scrollWidth;

Yscroll = Document.body.scrollHeight;

else {//Explorer mac...would also work in Explorer 6 Strict, Mozilla and Safari

Xscroll = Document.body.offsetWidth;

Yscroll = Document.body.offsetHeight;

WindowHeight = Document.body.clientHeight;

For small pages and total height less then height of the viewport

if (Yscroll < WindowHeight) {

PageHeight = WindowHeight;

} else {

PageHeight = Yscroll;

}

if (Xscroll < windowwidth) {

PageWidth = Xscroll;

} else {

PageWidth = WindowWidth;

}

Arraypagesize = new Array (PageWidth, PageHeight, WindowWidth, windowheight);

return arraypagesize;

}

Document.body.scrollTop;

$ (document). ScrollTop ();
