jquery - keyup not working on Chrome on Android -

i using bootstrap typeahead.

it depends on jquery code work:

el.on('keyup', dosomething() ) 

on chrome on windows works fine. on chrome on android doesn't. keyup event never fired. element bound has focus.

this appears recent development.

chrome 28.0.1500.64 android 4.1.2 sgp321 build/10.1.1.a.1.307

thanks

i came across same problem earlier today. how can android chrome not support these key events! assume you've found workaround now, here's fix came now.

function newkeyupdown(originalfunction, eventtype) {     return function() {         if ("ontouchstart" in document.documentelement) { // if it's touch device, or test here android chrome             var $element = $(this), $input = null;             if (/input/i.test($element.prop('tagname')))                 $input = $element;             else if ($('input', $element).size() > 0)                 $input = $($('input', $element).get(0));              if ($input) {                 var currentval = $input.val(), checkinterval = null;                 $input.focus(function(e) {                     clearinterval(checkinterval);                     checkinterval = setinterval(function() {                         if ($input.val() != currentval) {                             var event = jquery.event(eventtype);                             currentval = $input.val();                             event.which = event.keycode = (currentval && currentval.length > 0) ? currentval.charcodeat(currentval.length - 1) : '';                             $input.trigger(event);                         }                     }, 30);                 });                 $input.blur(function() {                     clearinterval(checkinterval);                 });             }         }         return originalfunction.apply(this, arguments);     } } $.fn.keyup = newkeyupdown($.fn.keyup, 'keyup'); $.fn.keydown = newkeyupdown($.fn.keydown, 'keydown');
