element-ui的tree组件,怎么根据数据data的checked属性为true,渲染时就能默认选中;里面有详情描述
请教,怎么根据 publish_treeData数据的expanded和checked属性去设置是否默认展开和默认选中的节点啊,比如disabled: true就能禁用状态
<el-tree :data="publish_treeData" show-checkbox node-key="id" :default-expanded-keys="defaultExpandedKeys" :default-checked-keys="defaultCheckedKeys" @setChecked="setCheckedFunc"> </el-tree>
publish_treeData: [{
id: 1,
label: '一级 2',
children: [{
id: 3,
label: '二级 2-1',
children: [{
id: 4,
label: '三级 3-1-1'
}, {
id: 5,
label: '三级 3-1-2',
expanded: true,
checked: true,
disabled: true
}]
}],
