如何在d3.js中删除嵌套元素

Question

I have an HTML structure like this

body
  svg
     g
      path d
      circle  (class=circles)
     g
      path d
      circle  (class=circles)
     g
     path d
     g
     path d
     g
      path d
      circle (class=circles)

I want to remove all circles from body->svg->g->circle with class=circles . Some "g" tags have circles with class as "circles".

Please guide me how to do this.

您可以使用DOM选择器在一行中完成此操作：

d3.selectAll("circle.circles").remove();
