D3JS删除类似于JQuery removeClass（）的类吗？

Question

Is there a D3JS equivalent to Jquery's removeClass() ?

I want to remove all classes from a circle shape. I currently explicitly name and remove each class:

.on("click", function() {
  d3.select("#circle" + i)
    .classed("foo", false)
    .classed("bar", false) 
  }

I could test for foo, bar, and remove only when present, but I want to anticipate as-yet unnamed classes for removal and make my code more efficient.

您可以使用d3.select("#circle" + i).attr("class", null)清除所选元素中的所有类。
