van-tree-select多选

vant 中van-tree-select的多选

<van-tree-select
:items=“items”
:main-active-index=“mainActiveIndex”
:active-id=“activeId”
@navclick=“onNavClick”
@itemclick=“onItemClick”
/>
exportdefault{
data(){
return{
items: items,
// 左侧高亮元素的index
mainActiveIndex:0,
// 被选中元素的id
activeId:1001
};
},
methods:{
onNavClick(index){
this.mainActiveIndex = index;
},
onItemClick(data){
this.activeId = data.id;
}
}
}

一定要在:active-id加入id标识，如果没有，可以自己push进去一个index座位id使用，灵感来源下面的链接
