Can you detect dragging in jQuery

Question

I have a throbber that is to appear when a user clicks a link   The problem is is that that same link can be clicked and dragged to be rearranged  In this case  I wouldn t need the throbber to appear  It only needs to appear if its actually waiting to go somewhere   How can I  with jQuery  create an event listener that would only allow a throbber to appear if its a click through to a link  and not a click and drag

If you re using jQueryUI - there is an onDrag event   If you re not  then attach your listener to mouseup    not click

You don t have to setup variable  you can just set if it is moving in data-attribute   youtubeSlider find  a        on  mousedown   function  e              this  data  moving   false               on  mousemove   function  e              this  data  moving   true               on  mouseup   function  e            if     this  data  moving                     Open link

For this simplest way is touch start  touch move and touch end  That is working for both PC and touch device just check it in jquery documentation and hope this is the best solution for you  good luck

Make sure you set the element s draggable attribute to false so you don t have side effects when listening to mouseup events    lt div class  thing  draggable  false  gt text lt  div gt    Then  you can use jQuery     function       var pressed  pressX  pressY        dragged        offset   3     helps detect when the user really meant to drag      document     on  mousedown     thing   function e        pressX   e pageX      pressY   e pageY      pressed   true          on  mousemove     thing   function e        if   pressed  return      dragged   Math abs e pageX - pressX   gt  offset                  Math abs e pageY - pressY   gt  offset          on  mouseup   function         dragged  amp  amp  console log  Thing dragged        pressed   dragged   false

For some reason  the above solutions were not working for me  I went with the following       container   on  mousedown   function e          this  data  p0     x  e pageX  y  e pageY        on  mouseup   function e        var p0     this  data  p0            p1     x  e pageX  y  e pageY            d   Math sqrt Math pow p1 x - p0 x  2    Math pow p1 y - p0 y  2         if  d  lt  4            alert  clicked               You can tweak the distance limit to whatever you please  or even take it all the way to zero

You ve need to set a timer  When the timer times out  start the throbber and register the click  When drag occurs  clear the timer so it never completes
