How to obtain the page width by using JavaScript

<Script> function getInfo () {var s = ""; s + = "visible area width:" + document. body. clientWidth; s + = "visible area of the webpage high:" + document. body. clientHeight; s + = "visible area width of the webpage:" + document. body. offsetWidth + "(including the width of the edge and scroll bar)"; s + = "visible area of the webpage Height:" + document. body. offsetHeight + "(including edge width)"; s + = "webpage text width:" + document. body. scrollWidth; s + = "webpage text Height:" + document. body. scrollHeight; s + = "the height of the page to which the page is rolled (ff):" + document. body. scrollTop; s + = "high page volume (ie):" + document.doc umentElement. scrollTop; s + = "left when the webpage is rolled:" + document. body. scrollLeft; s + = "webpage body part:" + window. screenTop; s + = "webpage body section left:" + window. screenLeft; s + = "high screen resolution:" + window. screen. height; s + = "Screen Resolution width:" + window. screen. width; s + = "available workspace height of the screen:" + window. screen. availHeight; s + = "available workspace width:" + window. screen. availWidth; s + = "your screen setting is" + window. screen. colorDepth + "bit color"; s + = "Your Screen Settings" + window. screen. deviceXDPI + "pixels/inches"; // alert (s);} getInfo (); </script>

In my local test:
It can be used in IE, FireFox, and Opera

document.body.clientWidthdocument.body.clientHeight

It is very simple and convenient.
In the company's projects:
Opera is still in use

document.body.clientWidthdocument.body.clientHeight

However, IE and FireFox use

document.documentElement.clientWidthdocument.documentElement.clientHeight

It turned out to be W3C standards.

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
If this line is added to the page

In IE:

Document. body. clientWidth => BODY object width document. body. clientHeight => bodyobject height document.doc umentElement. clientWidth => wide distance document.doc umentElement. clientHeight => visible area height

In FireFox:

Document. body. clientWidth => BODY object width document. body. clientHeight => bodyobject height document.doc umentElement. clientWidth => wide distance document.doc umentElement. clientHeight => visible area height

In Opera:

Document. body. clientWidth => visible area width document. body. clientHeight ==> zookeeper High Level document.doc umentElement. clientWidth ==> Page Object width (that is, the bodyobject width is added to the marginwidth extension document.doc umentElement. clientHeight => Page Object height (that is, the height of the BODY object plus the Margin height)

If W3C standards are not defined

IE:

document.documentElement.clientWidth ==> 0document.documentElement.clientHeight ==> 0

FireFox:
Copy codeThe Code is as follows: document.doc umentElement. clientWidth => Page Object width (that is, the width of the BODY object plus the Margin width)
Document.doc umentElement. clientHeight ==> Page Object height (that is, the height of the BODY object plus the Margin height)

Opera:

Copy codeThe Code is as follows: document.doc umentElement. clientWidth => Page Object width (that is, the width of the BODY object plus the Margin width)
Document.doc umentElement. clientHeight ==> Page Object height (that is, the height of the BODY object plus the Margin height)
