Getting Started
The code example in this blog is applicable to any web application which supports JavaScript code. In the below code example we will see, the best way to detect mobile devices and how can a server-side know whether a client-side is a mobile device or PC.
var isMobile = /iPhone|iPad|iPod|midp|rv:1.2.3.4|ucweb|windows ce|windows mobile|BlackBerry|IEMobile|Opera Mini|Android/i.test(navigator.userAgent);
The above code is the key code or main building block to detect device type, it work as server-side device detector and it has capability of request browser detection.
The below code, renders a button which calls JavaScript function 'checkdevide'. The JavaScript code identifies requests coming from mobile or PC, here we are not identifying specific devices for example whether it's iPhone or iPod or which mobile, it only identifies that whether it runs in mobile devices or desktop browsers. But you can identify the specific device by modifying the code.
Example of How to know request from mobile or desktop
<!DOCTYPE html>
<html>
<head>
<title>Device Borwser Detector</title>
<script type="text/javascript">
function checkdevide(){
var isMobile = /iPhone|iPad|iPod|midp|rv:1.2.3.4|ucweb|windows ce|windows mobile|BlackBerry|IEMobile|Opera Mini|Android/i.test(navigator.userAgent);
if (isMobile) {
alert("You are using Mobile");
} else {
alert("You are using Desktop");
}
}
</script>
</head>
<body>
<h1>Device Borwser Detector</h1>
Check Device :<button onclick="checkdevide()" width="50" height="50">Check</button>
</body>
</html>
Best way to detect mobile device
