How to Detect Mobile Devices using jQuery

Sam Deering

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.

/**
 * jQuery.browser.mobile (http://detectmobilebrowser.com/)
 * jQuery.browser.mobile will be true if the browser is a mobile device
 **/
(function(a){jQuery.browser.mobile=/android.+mobile|avantgo|bada/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)/|plucker|pocket|psp|symbian|treo|up.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw-(n|u)|c55/|capi|ccwa|cdm-|cell|chtm|cldc|cmd-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc-s|devi|dica|dmob|do(c|p)o|ds(12|-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(-|_)|g1 u|g560|gene|gf-5|g-mo|go(.w|od)|gr(ad|un)|haie|hcit|hd-(m|p|t)|hei-|hi(pt|ta)|hp( i|ip)|hs-c|ht(c(-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i-(20|go|ma)|i230|iac( |-|/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |/)|klon|kpt |kwc-|kyo(c|k)|le(no|xi)|lg( g|/(k|l|u)|50|54|e-|e/|-[a-w])|libw|lynx|m1-w|m3ga|m50/|ma(te|ui|xo)|mc(01|21|ca)|m-cr|me(di|rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|-([1-8]|c))|phil|pire|pl(ay|uc)|pn-2|po(ck|rt|se)|prox|psio|pt-g|qa-a|qc(07|12|21|32|60|-[2-7]|i-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55/|sa(ge|ma|mm|ms|ny|va)|sc(01|h-|oo|p-)|sdk/|se(c(-|0|1)|47|mc|nd|ri)|sgh-|shar|sie(-|m)|sk-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h-|v-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl-|tdg-|tel(i|m)|tim-|t-mo|to(pl|sh)|ts(70|m-|m3|m5)|tx-9|up(.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|xda(-|2|g)|yas-|your|zeto|zte-/i.test(a.substr(0,4))})(navigator.userAgent||navigator.vendor||window.opera);

    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'];
      break;
      }
      }

      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:
    (function(a){jQuery.browser.mobile=/android|avantgo|bada/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(ad|hone|od)|iris|kindle|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)/|plucker|pocket|psp|symbian|tablet|treo|up.(browser|link)|vodafone|wap|webos|windows (ce|phone)|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw-(n|u)|c55/|capi|ccwa|cdm-|cell|chtm|cldc|cmd-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc-s|devi|dica|dmob|do(c|p)o|ds(12|-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(-|_)|g1 u|g560|gene|gf-5|g-mo|go(.w|od)|gr(ad|un)|haie|hcit|hd-(m|p|t)|hei-|hi(pt|ta)|hp( i|ip)|hs-c|ht(c(-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i-(20|go|ma)|i230|iac( |-|/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |/)|klon|kpt |kwc-|kyo(c|k)|le(no|xi)|lg( g|/(k|l|u)|50|54|e-|e/|-[a-w])|libw|lynx|m1-w|m3ga|m50/|ma(te|ui|xo)|mc(01|21|ca)|m-cr|me(di|rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|-([1-8]|c))|phil|pire|pl(ay|uc)|pn-2|po(ck|rt|se)|prox|psio|pt-g|qa-a|qc(07|12|21|32|60|-[2-7]|i-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55/|sa(ge|ma|mm|ms|ny|va)|sc(01|h-|oo|p-)|sdk/|se(c(-|0|1)|47|mc|nd|ri)|sgh-|shar|sie(-|m)|sk-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h-|v-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl-|tdg-|tel(i|m)|tim-|t-mo|to(pl|sh)|ts(70|m-|m3|m5)|tx-9|up(.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|xda(-|2|g)|yas-|your|zeto|zte-/i.test(a.substr(0,4))})(navigator.userAgent||navigator.vendor||window.opera);

      Thanks so much!!

    • http://twitter.com/LReynaert Lode Reynaert

      Thx. Attention at the begin of this code: !!! jQuery.browser.mobile= …. 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.”

    • Val

      I’m a novice in jquery and would like to know how to implement this. I want to check if it’s mobile and then load mobile.css. Could you please guide me. Thanks.

    • Kartik

      How can i call function(a) and display number of device which has been caught using above script.

    this is awsome. perfectly working. thanks bro..

  • jeff

    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.

    Thanks :)

  • Till Pape

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