Question

这是css我试图获得透视原点

 #perspective {
    width: 200px;
   height: 200px;
  margin: 75px 0 0 75px;
  border: 1px solid black;
 transform:perspective-origin(center center);
 }

这个js我试图获得透视源，我想获得价值但是你没有工作

function getCssProperty(ele, property) {
var id = document.getElementById(ele);

return
window.getComputedStyle(id, null).getPropertyValue(property);

}//this is first  class perspective and property transform
 console.log(getCssProperty('perspective', 'transform'));

Answer 1

这样就可以了。我将研究变换：perspective-origin（center center）; vs perspective-origin：center center;

            /*transform: perspective-origin(center center);  this is not valid for the transform property;*/

        $("#target").click(function () {
