react: onClick broken on iOS.

iOS Safari really doesn’t want you clicking anything that’s not an <a> tag. This is a known issue: http://stackoverflow.com/questions/5421659/html-label-command-doesnt-work-in-iphone-browser/6472181#6472181

The way you fix this is by putting an empty “onclick” attribute on nodes you wish to emit click events. Yep.

So presumably:

div({onClick: function(){alert('clicked');}}, 'click me');

should emit:

<div onclick>click me</div>

on iOS. Ensuring that the click event is actually reachable from an iOS device.

As the stack overflow link points out, this is also an issue for <label> elements associated with <input> elements. In order to behave as a clickable label, they must also include an empty “onclick” attribute.

label(null, input({type: 'checkbox'}), check me);
<label onclick><input type="checkbox> check me</label>
