通过点击d3选择/取消选择

Question

我试图选择/取消选择单击的行（链接）。但我已经有鼠标悬停功能，它应该不同于鼠标悬停，当我选择一条线，该线的颜色需要改变，它需要绘制一个饼图，取消选择应该可用的点击。

我有什么：

nodeenter.on("mouseover", function(d){ 
console.log(d); 
d3.select(this).attr("fill", "yellow"); 

return tooltip.style("visibility", "visible").text("This node's id is: " + d.id + " and " + "Name: " + d.name);}) 
.on("mousemove", function(){ 

    return tooltip.style("top", 
    (d3.event.pageY-10)+"px").style("left",(d3.event.pageX+10)+"px");}) 
.on("mouseout", function(d){ 
    d3.select(this).attr("fill", "rgb(0, 0, " +(d*10) + ")"); 
    return tooltip.style("visibility", "hidden");}); 

link.on("mouseover", function(d){ 
    console.log(d) 
    d3.selectAll('.'+d.id).style('stroke','aqua'); 
    return tooltip.style("visibility", "visible").text("This line's id is: " + d.id + " and " + "Name: " + d.name);}) 
.on("mousemove", function(){return tooltip.style("top", 
    (d3.event.pageY-10)+"px").style("left",(d3.event.pageX+10)+"px");}) 
.on("mouseout", function(d){ 
    d3.selectAll('.'+d.id).style('stroke','black'); 
    return tooltip.style("visibility", "hidden");}); 

//to select 
link.on("click", function(d){ 
    if (!d3.select(this).classed("selected")){ 
    d3.select(this).classed("selected", true) 
    d3.select(this).style("stroke","red"); 
    }else{ 
    d3.select(this).classed("selected", false); 
    d3.select(this).style("stroke","black"); 
    } 
});

这里的结果：https://jsfiddle.net/xcn35ycm/4/

我绑定一个上点击功能的链接。

links.on("click", function(d){ 
    if (!d3.select(this).classed("selected")){ 
    d3.select(this).classed("selected", true) 
    d3.select(this).transition().attr("stroke","red"); 
    }else{ 
    d3.select(this).classed("selected", false); 
    d3.select(this).transition().attr("stroke","black"); 
    } 

，并更新鼠标移开功能

.on("mouseout", function(d){ 
    if(!d3.select(this).classed("selected")){ 
    d3.selectAll('.'+d.id).style('stroke','black'); 
    return tooltip.style("visibility", "hidden"); 
    } 
});
