GoJS中如何动态添加Node数据和Link数据？

Question

 myDiagram.model = new go.GraphLinksModel(
[

  { key: "Alpha", color: "lightblue" },
  { key: "Delta", color: "pink" }

],
[
  { from: "Alpha", to: "Alpha" },
  { from: "Delta", to: "Alpha" }
]);

我需要动态添加更多值，我应该怎么做？

Answer 1

节点数据（来源：GoJS docs, class Model）：

If you want to add or remove node data from the nodeDataArray, call the addNodeData or removeNodeData methods.

Link 数据（来源：GoJS docs, class GraphLinksModel）：

If you want to add or remove link data from the linkDataArray, call the addLinkData or removeLinkData methods. If you want to modify the node a link connects to, call the setFromKeyForLinkData and/or setToKeyForLinkData methods.

从对象列表动态添加到 GraphLinksModel 的示例：

       var model = new go.GraphLinksModel();
        for(let id = 1; id < node_list.length; id++){
       model.addNodeData( { key: node_list[id].getNodeID(), color: "lightblue" } );
       model.addLinkData( { from: node_list[id].getPreviousNode(), to: node_list[id].getNodeID() } );
         }
       myDiagram.model = model;  
       console.log(model.nodeDataArray); //to see data
