Javascript - GoJS 流程图

Question

我正在使用 Flowchart来自 http://gojs.net/latest/samples/flowchart.html它工作正常。唯一的问题是，它没有 t display the toolbar symbols which are shown in the example. Have someone used Flowchart` 也有同样的问题吗？

var $ = go.GraphObject.make;

myPalette =
                    $(go.Palette, "myPaletteDiv",  // must name or refer to the DIV HTML element
                        {
                            "animationManager.duration": 800, // slightly longer than default (600ms) animation
                            nodeTemplateMap: myDiagram.nodeTemplateMap,  // share the templates used by myDiagram
                            model: new go.GraphLinksModel([  // specify the contents of the Palette
                                {category: "Start", text: "Start"},
                                {text: "Step"},
                                {text: "???", figure: "Diamond"},
                                {category: "End", text: "End"},
                                {category: "Comment", text: "Comment"}
                            ])
                        });

我认为您在初始化 Diagram 及其 Diagram.nodeTemplateMap 之前正在初始化 Palette。这实际上意味着 Palette 没有使用您的自定义模板，因此 Palette 中的节点正在使用默认节点模板。

如果您查看流程图示例中的源代码，您会看到:

// initialize the Palette that is on the left side of the page
myPalette =
  $(go.Palette, "myPaletteDiv",  // must name or refer to the DIV HTML element
    {
      "animationManager.duration": 800, // slightly longer than default (600ms) animation
      nodeTemplateMap: myDiagram.nodeTemplateMap,  // share the templates used by myDiagram
