如下图所示，对节点常用的事件如下图所示：

主要代码：

// 鼠标进入节点
this.graph.on('node:mouseenter', (e) => {
    const nodeItem = e.item // 获取鼠标进入的节点元素对象
    console.log('鼠标移入', nodeItem._cfg)
})
// 单击节点
this.graph.on('node:click', (e) => {
    const nodeItem = e.item // 获取被点击的节点元素对象
    console.log('单击', nodeItem._cfg)
})
// 双击节点
this.graph.on('node:dblclick', (e) => {
    const nodeItem = e.item // 获取被点击的节点元素对象
    console.log('双击', nodeItem._cfg)
})
