How to trigger hover when mouse on a child div
<p>I have this:</p>

<pre><code>&lt;div id='hasHover'&gt;
  &lt;div id='inner-button' style='display:none'&gt;Click&lt;/div&gt;
&lt;/div&gt;

$('#hasHover').hover(function(){
  $('inner-button').toggle();
});
</code></pre>

<p>This works fine. However when I move my mouse to the button, the button disappears(or flashes really fast). How to make sure the button stays when the mouse is hovering on the div (including child div)?</p>
