Question

joint.dia.Graph.prototype.clear对我不起作用。当我清除并记录图形时，它似乎仍然包含所有元素。清除异步功能了吗？

this.graph.clear();
appLogger.info({graph: this.graph}, "Graph with zero elem");

给予

[2019-11-28T21:03:46+05:30] info: Graph with zero elem
graph: child
attributes:
cells: child
    cellNamespace: null
    graph: child {cid: "c1", attributes: {…}, _changing: false, _previousAttributes: {…}, changed: {…}, …}
    length: 3
    models: (3) [child, child, child]

_changing: false**

能请你帮忙吗？

此方法非常简单，没有陷阱。它通过调用元素/链接上的remove一一删除所有单元格。您是否在任何单元格上都覆盖了remove？特别是图中剩下的3个？

JointJS：joint.dia.Graph.prototype.clear不起作用
