推荐答案

您可以使用 步骤 -callback ，您在动画选项中传递以在每一步执行一个函数。你可以调查一下。

You can use the step-callback, which you pass in the animation options to execute a function on every step. You could look into that.

$('#myElement').animate({/*Your animation options.*/}, {
  step: function(current_number){
    /* measure stuff using the first argument passed to this function */
  }
})
