-
Example:
<!DOCTYPE html><html><head><title>Detect whether a device is iOSwithout using RegExp</title></head><bodystyle="text-align: center;"><h1style="color: green;">GeeksforGeeks</h1><p>Click on the button to detectwhether a device is iOS or not?</p><buttononclick="gfg_Run()">Click Here</button><pid="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.

<!DOCTYPE html><html><head><title>Detect whether a device isiOS without using RegExp</title></head><bodystyle="text-align: center;"><h1style="color: green;">GeeksforGeeks</h1><p>Click on the button to detectwhether a device is iOS or not?</p><buttononclick="gfg_Run()">Click Here</button><pid="gfg"></p><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> -
Output:
