element ui el-tree组件 首项选中效果
默认首项选中效果
dom层,
指定key(业务id),ref="tree",highlight-current-row,:highlight-current="true"属性加上
el-tree(
:data="typeArr",
ref="tree",
:highlight-current="true",
highlight-current-row,
node-key="equipTypeId",
@node-click="handleNodeClick",
default-expand-all,
:expand-on-click-node="false"
)
script层
setCurrentKey,设置首项的业务id
watch: {
"$store.state.devMng.devType": function (n) {
this.typeArr = n;
this.$nextTick(() => {
this.$refs.tree.setCurrentKey(n[0].equipTypeId);
});
},
},
这样就好了
