el-radio-group 點擊後不更新問題備忘

        <el-radio-group v-model="obj.type" @change="type_change()"> 
          <el-radio label="1" key="1" border>aaaa</el-radio>
          <el-radio label="3" key="3" border>bbb</el-radio>
          <el-radio label="5" key="5" border>ccc</el-radio> 
        </el-radio-group>

 

type_change: function() {
      console.log(this.obj.type) 

       // 一些處理
       this.project_shops = null

       this.from_sets = []       

       this.$forceUpdate();   //需要加上這句

}
