javascript - D3 SelectAll 除了一类修改不透明度

Question

我正在研究以下径向图:

 //Fade out all players except the first player
        g.selectAll(".teamArc")
                .attr("opacity", 0.6);

        g.selectAll(".teamCircle")
                .attr("opacity", 0.6);

        //Select the first player by default
        var firstPlayer = arcAndCircleG.first();

        firstPlayer.select(".teamArc")
                    .classed("active", true)
                    .attr("id", "selected")
                    .attr("stroke", "green")
                    .attr("stroke-width", "1px")
                    .attr("opacity", 1);

        firstPlayer.select(".teamCircle")
                    .classed("active", true)
                    .attr("id", "selected")
                    .attr("stroke", "green")
                    .attr("stroke-width", "1px")
                    .attr("opacity", 1);


        teamCircles.on("mouseover", function(d,i){

            g.selectAll(".teamArc").transition()
                    .duration(200)
                    .attr("opacity", function(d,j){

默认情况下，我希望第一个“玩家”(圆弧和圆)处于事件状态。当用户将鼠标悬停在另一个圆弧或圆上时，除了曾经处于事件状态和正在悬停的那个之外，所有圆弧和圆都应淡化为不透明度 0.6。

我遇到的问题是，当我悬停时，所有圆弧和圆(包括事件圆)都在淡出。

您可以过滤您的选择并拒绝具有“事件”类的元素。

teamArcs.on("mouseover", function(d, i) {
  //The following bit of code adapted from http://bl.ocks.org/WillTurman/4631136
  console.log("hello");
  g.selectAll(".teamArc")
    .filter(function() {
      return !this.classList.contains('active')
    })
    .transition()
    .duration(200)
    .attr("opacity", function(d, j) {
      return j != i - 1 ? 0.6 : 1;
    });

  g.selectAll(".teamCircle").transition()
    .filter(function() {
      return !this.classList.contains('active')
    })
    .duration(200)
    .attr("opacity", function(d, j) {
      return j != i - 1 ? 0.6 : 1;
    });
});
