johnsardine / context_events.js
Created January 3, 2014 10:44
When triggering events on selected elements on another context, events are not triggered. see solution below
var context = top.window;
// Instead of this
var target = jQuery('#'+data.target, context.document);
// Do this
var target = context.jQuery('#'+data.target);
target.val(data.value).trigger('change');

Advanced Checkbox Hack

This works for both iOS and Android! You can use almost the default checkbox-hack syntax and just need to add two things:

1. Android smaller than / equal 4.1.2

pseudo-class + general/adjacent sibling doesn't work on Android 4.1.2 so we need a hack:

body { -webkit-animation: bugfix infinite 1s; }
@-webkit-keyframes bugfix { from {padding:0;} to {padding:0;} }
