el-tree 清除单选选中
时间: 2024-01-11 20:03:54 浏览: 82
您可以使用`el-tree`的`setCheckedKeys`方法来清除单选选中。该方法接受一个空数组作为参数,将清除所有选中的节点。
以下是一个示例代码:
```javascript
// 清除单选选中
this.$refs.tree.setCheckedKeys([]);
```
请注意,您需要在`el-tree`上添加`ref`属性,并将其值设置为`tree`,以便在代码中引用该组件。

el-tree设置单选选中
要将el-tree设置为单选选中,可以使用check-strictly属性并将其设置为true。这样可以关闭父子节点之间的关联,实现单选功能。同时,还需要将show-checkbox属性设置为false,以隐藏复选框。具体的代码示例如下:
<el-tree ref="tree" highlight-current="true" accordion :data="treeData" :default-expanded-keys="treeExpandData" node-key="id" check-strictly="true" show-checkbox="false" :props="treeDefaultProps" @check="checkGroupNode">
</el-tree>
通过以上的代码设置,el-tree将只能单选选中节点。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

el-tree 清除树选中
要清除 el-tree 组件中树的选中状态,可以通过以下两种方式实现:
1. 直接调用 el-tree 的 clearSelection 方法:
```
<el-button @click="clearSelection">清除选中</el-button>
...
methods: {
clearSelection() {
this.$refs.tree.clearSelection();
}
}
```
2. 手动遍历树的节点,将节点的 checked 属性设置为 false:
```
<el-button @click="clearSelection">清除选中</el-button>
...
methods: {
clearSelection() {
const traverse = (node) => {
node.checked = false;
if (node.children) {
node.children.forEach(child => {
traverse(child);
});
}
};
this.$refs.tree.store.root.childNodes.forEach(node => {
traverse(node);
});
}
}
```
