el-radio编辑选不中和el-tree相关问题

1.解决el-raido选不中的问题

onSelectChange() {
      this.$forceUpdate();
    }

2.el-tree复选框选中选中的id值

//前提条件node-key="id"

<el-tree :data="list"  :props="defaultProps" show-checkbox  node-key="id" ref="tree" :highlight-current="true" @check="check" @node-click="handleNodeClick"></el-tree>

//获取ids值
let res = this.$refs.tree.getCheckedKeys().concat(this.$refs.tree.getHalfCheckedKeys())

3.el-tree编辑复选框回显问题

//default-checked-keys 通过这个设置回显
<el-tree :data="list"  :props="defaultProps" :default-checked-keys="defaultChecks"    default-expand-all  show-checkbox  node-key="id" ref="tree" :highlight-current="true" @check="check" @node-click="handleNodeClick"></el-tree>

//defaultChecks:[]
//举例:defaultChecks[29,32]  这里面的29和32是node-key的值
