我工作正常。现在我需要根据＆＃39; status＆＃39;更改目标节点（矩形）的颜色。属性。
为了实现这一点，我创建了下面的CSS类 -
.finished {
fill: green;
}
.pending {
fill: blue;
}
.dormant {
fill: purple;
}
并更改了
.classed("node", true)
到
.style("fill", function (d) { return d3.select(this).classed(edges[d.status], true)})
这导致所有节点都被涂成黑色。
有人可以帮我确定问题。

答案 0 :(得分：1)
如果可以，请更改数据结构，以便status成为节点数组的一部分。这使事情变得容易一些。如果你不能，你将不得不迭代edge数组来找到与节点数组的匹配：
var node = vis.selectAll(".node")
.data(nodes)
.enter().append("rect")
.attr('class',function(d){ //<-- don't need classed, attr is fine
var N = edges.length;
for (var i = 0; i < N; i++){
if (edges[i].source_name === d.nodes){
return edges[i].status; //<-- found it and return status
}
}
})
.attr({ rx: 5, ry: 5 })
.call(d3cola.drag);
更新了example。
