在dagre-d3中單擊節點

Question

我正在使用degre-d3，但在獲取被單擊節點的節點數據時遇到問題。 單擊時我有一個事件，但d3.select（this）似乎無法獲得相關數據（如果可能，我希望獲得節點名稱，標簽和其他對象數據）。

app.controller "DashboardElementShowController", ($scope, DashboardElementIndexService) ->
  init_app = ->
    # Create a new directed graph
    g = new dagreD3.Digraph()

    g.addNode "bpitt",
      label: "html Brad Pitt <b>test</b>"
    g.addNode "hford",
      label: "Harrison Ford"
    g.addNode "lwilson",
      label: "Luke Wilson"
    g.addNode "kbacon",
      label: "Kevin Bacon"

    g.addEdge null, "bpitt", "kbacon",
    g.addEdge null, "hford", "lwilson",
    g.addEdge null, "lwilson", "kbacon",

    renderer = new dagreD3.Renderer().edgeInterpolate("cardinal")
                .edgeTension(0.8)
    renderer.edgeInterpolate('linear');
    renderer.run g, d3.select("svg g")
    d3.select("svg g").on("click", (d, i, k) ->
      console.log d3.select(this) # doesn't seem to have relevant info I need
    )


  init_app()

編輯：10.09.2014：在這里說我必須重寫renderer.drawNodes方法： https : //github.com/cpettitt/dagre-d3/issues/67

這是指定的代碼：

constructor:
  @renderer.drawNodes @_drawNodes().bind @

_drawNodes: ->
  oldDrawNodes = @renderer.drawNodes()
  (graph, svg) ->
    # catch drawed nodes
    svgNodes = oldDrawNodes graph, svg
    svgNodes.on 'click', (nodeId) -> console.log 'node clicked', nodeId

我不確定該如何以及在何處覆蓋此代碼...
