jquery - 平滑修改 css 剪辑路径

Question

我有一个带有 css clip-path 的元素。 根据光标位置 (Xcord) jquery 修改 clip-path 点。

我的代码工作得很好，但我想放慢(缓慢而平滑)这个“动画”，即使光标移动得很快。

我怎样才能做到这一点？感谢帮助

$(document).mousemove(function(getCurrentPos){
  var clip = $(".element");
  //x coordinates
  var xCord = getCurrentPos.pageX;
  //calculate %
  xPercent = xCord / $(document).width() * 100;
  var left = 90 + 10 * (xPercent / 100);
  var right = 100 - 10 * (xPercent / 100);
					
  $(".element").css('clip-path', 'polygon(0% 0%, 100% 0%, 100% ' + left + '%, 0% ' + right + '%)');
});

.element {
background:red;
width:500px;
height:150px;
clip-path:polygon(0% 0%, 100% 0%, 100% 100%, 0% 90%);
}

只需在 CSS 代码上添加一个过渡

$(document).mousemove(function(getCurrentPos) {
  var clip = $(".element");
  //x coordinates
  var xCord = getCurrentPos.pageX;
  //calculate %
  xPercent = xCord / $(document).width() * 100;
  var left = 90 + 10 * (xPercent / 100);
  var right = 100 - 10 * (xPercent / 100);

  $(".element").css('clip-path', 'polygon(0% 0%, 100% 0%, 100% ' + left + '%, 0% ' + right + '%)');
});

.element {
  background: red;
  width: 500px;
  height: 150px;
  clip-path: polygon(0% 0%, 100% 0%, 100% 100%, 0% 90%);
  transition:0.5s;
}
