Onclick event in web applications in desktop and iOS browsers?

Question

JavaScript

In the iOS Safari browser, the onClick event fires after ~400ms (you can check it here ). To avoid this, you can use the touchstart event.
Is it possible to somehow determine for all elements on the page if it has an onClick handler? then replace onClick with touchstart. Better if it's in jQuery.

Now I explicitly indicate why I need to replace the handlers

$('.sidebar_item').live('touchstart', function(e) {<br>
  $(this).click();<br>
  e.preventDefault();<br>
});<br>

Here we need the same thing, but for all elements. Please tell me how to do it.

Tried like this:

$('*').each(function() {<br>
  var me = $(this);<br>
  if(me.click != null) {<br>
    // но me.click есть для всех элементов<br>
  }<br>
});

Answer 1

Maybe so?

$('*[onclick]').live('touchstart', function(e) {
  $(this).trigger('click');
  e.preventDefault();
});
