You can use this minified jQuery snippet to detect if your user is viewing using a mobile device. If you need to test for a specific device I’ve included a collection of JavaScript snippets below which can be used to detect various mobile handheld devices such as iPad, iPhone, iPod, iDevice, Andriod, Blackberry, WebOs and Windows Phone.

  • Maximus Saint

    awesome! but would be even more awesomer  if you could set this thing up based on screen resolution, like we do with mediaqueries…

    Thanks anyway.

    • Friso

      Maximus, you mean something like below? I *was* using this, but it didn’t work for me. I was using it to serve out the rightfull video stream (live stream) per device. But obviously when a client is using a very low resolution on a desktop the javascript will think it is a tablet and thus show a low bandwith stream… But maybe someone else could use it tho:

      function device_detection() {
      devices = new Array();
      devices[0] = new Array();

      devices[0][‘min’] = 0;
      devices[0][‘max’] = 649;
      devices[0][‘device’] = ‘phone’;

      devices[1] = new Array();
      devices[1][‘min’] = 650;
      devices[1][‘max’] = 1154;
      devices[1][‘device’] = ‘tablet’;

      devices[2] = new Array();
      devices[2][‘min’] = 1155;
      devices[2][‘max’] = 99999;
      devices[2][‘device’] = ‘desktop’;

      found = false;
      for(i = 0; i = device[‘min’]) && (screen.width <= device['max'])) {
      found = device['device'];

      return found;

      • Peo

        this is awsome, thanks

  • CodeHunger

    This is great! why isn’t this a jquery plugin?

  • Verulam

    I wanted to detect any mobile device including tablets, not just smartphones, so I have modified the regex as below:
    changed android.+mobile to android [any Android device]
    changed ip(hone|od) to ip(ad|hone|od) [addsiPad]
    added tablet [catch-all for tablets]
    added webos [adds the ill-fated HP tablet!];
    the complete thing is now:

      Thanks so much!!

      Thx. Attention at the begin of this code: !!! …. must be (jQuery.browser=jQuery.browser||{}).mobile=… !!! If you don’t write this, you get the error: “Uncaught TypeError: Cannot set the property ‘mobile’ of undefined.”

    Liddle widdle change you gotta make to update for iPads; replace “|ip(hone|od)|” with “|ip(hone|od|ad)|”. Least I had to do this to get my iPad recognized as mobile.

  • Suj

    Another legendary post. Awesome. Works pretty well.

  • Behzad G

    Thanks :)

  • Till Pape

    The first example does not work because $.browser is not suppurted in jQuery any more. A simple fix is to replace with browserMobile.

    Hi guys i am trying to implement this feature into my big cartel site, i was wondering if you could help me. I call my scripts i want in a file called layout. Here is where i am guessing that i add in the function call. This is also where i guess i will call the $ getscript function?

    At the moment nothing is working, even the console log, as a newb i am finding this a little bit difficult. Many thanks.

  • Peter Nguyen

    Hi! I use a plugin to switch to another page, so you need to use window.location.href (‘’) or other code? So I checked on the iPhone and found location.href () or location.reload () will not run.
