[JavaScript] Width of Browser Window in Pixel
Updated: February 26, 2015
Here is an interesting and sometimes practical question:
How do I get the width of browser window in pixel?
The answer is easy: add a div element right after the body tag, make it 100% wide, and get the offsetWidth property of the div.
Source Code for Demo:
getWindowWidthPixel.html | repository | view raw
<!doctype html> <html> <head> <meta charset="utf-8"> <title>[JavaScript] Width of Browser Window in Pixel</title> </head> <body> <div id="width" style="width: 100%"> </div> <div id="info"></div> <script type="text/javascript"> var width = document.getElementById("width").offsetWidth; document.getElementById('info').innerHTML = 'The width of browser window is ' + width + ' pixels.'; document.getElementById("width").parentNode.removeChild(document.getElementById("width")); </script> </body> </html>
