 $(function () {  
     $('#btnShow').click(function (event) {  
         //Cancel Event Bubble  
         event.stopPropagation();  
         //Button toggle, if div is visible, click the button to switch to hidden; if hidden, switch to visible.  
         $('#divTop').toggle('slow');  
		 return false;
     });  
     //Hide the pop-up layer by clicking in the empty space. Below are the sliding disappearance effect and the fading disappearance effect.
	 $(document).click(function(event){
		  var _con = $('#divTop');   // Set target area
		  if(!_con.is(event.target) && _con.has(event.target).length === 0){ // Mark 1
			//$('#divTop').slideUp('slow'); //slide disappears
			$('#divTop').hide(1000);          //Fade out disappear

HTML code:

<body>
<input type="button" id="btnShow" value="pop-up button"/>
<div id="divTop">

</div>
</body>

After testing, clicking on the pop-up layer to close the page blank on the mobile Iphone phone is invalid. Doument writing is not supported. Solution: You can add a background layer to handle the page blank object.

Hide the pop-up layer by clicking in the blanks Case 2:
