javascript - iView中 tree 树控件 的方法调用有错
官网的说明
Tree methods
| 方法名 | 说明 | 参数 |
| getCheckedNodes | 获取被勾选的节点 | 无 |
| getSelectedNodes | 获取被选中的节点 | 无 |
自己撸的代码----------------------------------
<button @click='getCheckedNodes'>获取被选中的节点</button>
<button @click="getSelectedNodes">获取被勾选的节点</button>自己撸的代码---------------------------
getCheckedNodes(){
console.log(this.$refs.Tree.getCheckedNodes());
},
getSelectedNodes(){
console.log(this.$refs.tree.getSelectedNodes);
}报错
