javascript - How can I call click event when drag and drop event -

I want to change the event drag and drop to click on the event for my object. I try this code < P>

  $ ("a"). Draggable ({start: function (event, ui) {$ (this) .trigger ("click");}});   
 but not working: ( 
  Update:   
 I try this code:  
  document.ondragstart = function () {return false;}; document.onmouseup = function (a, b) {$ (this) .trigger ("click");};   
 But trigger click still does not work   
 
 
 Try with this modification :  
  $ ("a"). Draggable ({start: function (Event, UI) {$ (- your-button-element-here-) click ();}}) ;
