The task is to detect whether the device is iOS or not without using RegExp with the help of JavaScript. There are two approaches that are discussed below.
Approach 1: Use navigator.platform property to check for the particular keywords which belongs to iOS devices using indexOf() method.
- Example:
<!DOCTYPE html>
<html>
<head>
<title>
Detect whether a device is iOS
without using RegExp
</title>
</head>
<body style="text-align: center;">
<h1 style="color: green;">
GeeksforGeeks
</h1>
<p>
Click on the button to detect
whether a device is iOS or not?
</p>
<button onclick="gfg_Run()">
Click Here
</button>
<p id="gfg"></p>
<script>
var el_down = document.getElementById("gfg");
function gfg_Run() {
const isIOS = ["iPad Simulator",
"iPhone Simulator",
"iPod Simulator",
"iPad", "iPhone",
"iPod"]
.indexOf(navigator.platform) !== -1;
el_down.innerHTML = isIOS;
}
</script>
</body>
</html>
|
- Output:
Approach 2: Use navigator.platform property to check for the particular keywords from the list Which belongs to iOS devices. Use pop() method to take out one by one and compare them.
- Example:
<!DOCTYPE html>
<html>
<head>
<title>
Detect whether a device is
iOS without using RegExp
</title>
</head>
<body style="text-align: center;">
<h1 style="color: green;">

<script>
var el_down = document.getElementById("gfg");
function iOS() {
var Devices = ["iPad Simulator",
"iPhone Simulator",
"iPod Simulator",
"iPad", "iPhone",
"iPod"];
if (!!navigator.platform) {
while (Devices.length) {
if (navigator.platform === Devices.pop()) {
return true;
}
}
}
return false;
}
function gfg_Run() {
el_down.innerHTML = iOS();
}
</script>
</body>
</html>
