getting the X Y coordinates of a mouse click on an image with jQuery

Question

I would like to use jQuery to get the X Y coordinates of a click event on an image  The coordinates should be relative to the image  not relative to the whole page

You can use pageX and pageY to get the position of the mouse in the window  You can also use jQuery s offset to get the position of an element   So  it should be pageX - offset left for how far from the left of the image and pageY - offset top for how far from the top of the image   Here is an example     document  ready function          img   click function e        var offset     this  offset        alert e pageX - offset left       alert e pageY - offset top               I ve made a live example here and here is the source   To calculate how far from the bottom or right  you would have to use jQuery s width and height methods

note  there is a difference between e clientX  amp  e clientY and e pageX and e pageY  try them both out and make sure you are using the proper one  clientX and clientY change based on scrolling position

The below code works always even if any image makes the window scroll     function             demo-box   click function e           var offset     this  offset          var relativeX    e pageX - offset left         var relativeY    e pageY - offset top          alert  X      relativeX      Y      relativeY                  Ref  http   css-tricks com snippets jquery get-x-y-mouse-coordinates

Take a look at http   jsfiddle net TroyAlford ZZEk8  for a working example of the below    lt img id  myImg  src   my img link gif    gt    lt script type  text javascript  gt        document  bind  click   function                 Add a click-handler to the image              myImg   bind  click   function  ev                var  img     ev target                var offset    img offset                var x   ev clientX - offset left              var y   ev clientY - offset top               alert  clicked at x      x      y      y                        lt  script gt    Note that the above will get you the x and the y relative to the image s box - but will not correctly take into account margin  border and padding  These elements aren t actually part of the image  in your case - but they might be part of the element that you would want to take into account   In this case  you should also use  div outerWidth true  -  div width   and  div outerHeight true  -  div height   to calculate the amount of margin   border   etc   Your new code might look more like    lt img id  myImg  src   my img link gif    gt    lt script type  text javascript  gt        document  bind  click   function                 Add a click-handler to the image              myImg   bind  click   function  ev                var  img     ev target                var offset    img offset       Offset from the corner of the page              var xMargin     img outerWidth   -  img width      2              var yMargin     img outerHeight   -  img height      2                 Note that the above calculations assume your left margin is                 equal to your right margin  top to bottom  etc  and the same                 for borders               var x    ev clientX   xMargin  - offset left              var y    ev clientY   yMargin  - offset top               alert  clicked at x      x      y      y                        lt  script gt
