Available options with notes, the values here are the defaults.

  size        : 5,          // The size of the brush/scratch.
  bg          : '#cacaca',  // Background (image path or hex color).
  fg          : '#6699ff',  // Foreground (image path or hex color).
  realtime    : true,       // Calculates percentage in realitime.
  scratchDown : null,       // Set scratchDown callback.
  scratchUp   : null,       // Set scratchUp callback.
  scratchMove : null,       // Set scratcMove callback.
  cursor      : 'crosshair' // Set cursor.

Note on realtime, if set to false this will only send percentage calculations to the scratchUp and should be used to increase performance.

Note on bg and fg, these can be eitehr a valid hex color beginning with # otherwise it will default to trying to set an image.


Include the following files:

<script type="text/javascript" src="./wScratchPad.min.js"></script>

Percent scratched

  scratchDown: function(e, percent){ console.log(percent); },
  scratchMove: function(e, percent){ console.log(percent); },
  scratchUp: function(e, percent){ console.log(percent); }

Update on the Fly

var sp = $("#elem").wScratchPad();

sp.wScratchPad('size', 5);
sp.wScratchPad('cursor', 'url("./cursors/coin.png") 5 5, default');

// Or directly with element.

$("#elem").wScratchPad('image', './images/winner.png');


$('#elem').wScratchPad('enabled', <boolean>);
