javascript - How to Fetch Coordinate Value (x,y) from jQuery Code and Store in NSString? -

div tag used performing bold, italic, etc. operations in uiwebview. want fetch position coordinates when user touches div tag through javascript/jquery.

i found code in jsfiddle.

$(document).ready(function(e) {      $('#c').click(function(e) {          var posx = $(this).position().left, posy = $(this).position().top;          var x =  e.pagex - posx;          var y =  e.pagey - posy;          alert( (x) + ' , ' + (y));      });  });

#c {       width: 100px;      height: 100px;      cursor: pointer;      background: #2f2f2f;      position: absolute;      top: 50px;      color: #fff;      font: bold 15px arial;   }

<div id="c" style="left:500px;">      position() <br />       mouse <br/>       position   </div>
