Get Browser Screen Width and Height dynamically using jQuery

In order to get screen width and height of your browser window using jQuery check out the below code. As you resize your browser window the values of the width and height of the frame are displayed.

This code can be quite handy when your testing your responsive design of your website. You can view this page on various devices to get the height and width.

Code Example:

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="../js/jquery-1.10.2.min.js" >
</script>
<style>
#display {
        width: auto;
        height:22px;
        background-color: #ccc;
        color: #222;
        margin-left: 5px;
        font-size:20px;
        text-align: center;
    }
</style>
</head>
<body>
<script>
$("#display").html("<b>Width</b> : " + 
       $(window).width() + ",<b>Height : </b>" +
       $(window).height());
$(window).resize(function() {
        $("#display\").html("<b>Width</b> : " +
        $(window).width() + ",<b>Height : </b>" +
        $(window).height());
});
    </script>
<div id="display"></div>
</body>
</html>
