elementPlus的el-tree,获取鼠标覆盖行的id
时间: 2024-03-19 16:45:37 浏览: 5
您可以使用`mouseover`事件来获取鼠标覆盖行的id,具体步骤如下:
1. 给`el-tree`绑定`mouseover`事件,如下所示:
```html
<el-tree
ref="tree"
:data="data"
@mouseover="handleMouseover"
:default-expand-all="true"
:props="defaultProps">
</el-tree>
```
2. 在`methods`中定义`handleMouseover`函数,获取当前鼠标覆盖的行的id,如下所示:
```js
methods: {
handleMouseover(e, data) {
// 获取当前鼠标覆盖的行的id
const id = data.id;
console.log(id);
}
}
```
在`handleMouseover`函数中,`data`参数表示当前鼠标覆盖的行的数据,其中包含了该行的`id`属性。通过获取`data.id`即可获取当前鼠标覆盖的行的id。

elementplus el-tree-select
Element Plus 是一个基于 Vue.js 的 UI 组件库,el-tree-select 是其中的一个组件。el-tree-select 是一个树形选择器,可以用于选择树形结构的数据。
使用 el-tree-select 需要先安装 Element Plus,然后在你的项目中引入 el-tree-select 组件。你可以通过以下方式使用 el-tree-select:
1. 引入样式和脚本文件:
```html
<link rel="stylesheet" href="https://unpkg.com/element-plus/lib/theme-chalk/index.css">
<script src="https://unpkg.com/vue@next"></script>
<script src="https://unpkg.com/element-plus/lib/index.full.js"></script>
```
2. 在 Vue 组件中使用 el-tree-select:
```html
<template>
<el-tree-select v-model="selectedNodes" :data="treeData"></el-tree-select>
</template>
<script>
import { ElTreeSelect } from 'element-plus';
export default {
components: {
ElTreeSelect
},
data() {
return {
selectedNodes: [],
treeData: [
{
label: 'Node 1',
children: [
{
label: 'Node 1-1',
children: [
{
label: 'Node 1-1-1'
},
{
label: 'Node 1-1-2'
}
]
},
{
label: 'Node 1-2'
}
]
},
{
label: 'Node 2'
}
]
};
}
};
</script>
```
上述代码中,`treeData` 是树形数据的数组,`selectedNodes` 是选中的节点数组。你可以根据自己的需求进行修改和扩展。
