Say a div has this applied to it:
-webkit-transform: translate3d(0px, -200px, 0px)
How could I retrieve those values with jQuery?
If you update the regular expression to the following it adds supports for those odd cases when your transform has floats:
/matrix(?:(3d)\(-{0,1}\d+\.?\d*(?:, -{0,1}\d+\.?\d*)*(?:, (-{0,1}\d+\.?\d*))(?:, (-{0,1}\d+\.?\d*))(?:, (-{0,1}\d+\.?\d*)), -{0,1}\d+\.?\d*\)|\(-{0,1}\d+\.?\d*(?:, -{0,1}\d+\.?\d*)*(?:, (-{0,1}\d+\.?\d*))(?:, (-{0,1}\d+\.?\d*))\))/
