技术：vue+element ， 来决策el-form表单中的一项展示，进而便于用户选择

项目场景：

一张表格：通过接口获取数据并遍历生成的表格；
一个表单：在另一个界面的表单，需借用表格中的一个属性值；
注意：该两个界面在同一个组件中

问题描述：

问题一：如何从表格中获取该属性值？
问题二：如何将该属性值传入data中？

原因分析：

业务需要：便于用户更好的操作和体验感

解决方案：

记得你在data（）中的一些定义？

data(){
	return {
		table1:[],   //表格中的:data="table1"
		table2:[],
		...
	}
}

可以调用this.table1在要使用的函数或位置

#案例

写法一：
 async submitInstitution(){
        var thorg = this.orgnizationTable
        for(let index in thorg){ var onID = thorg[index].id }
        var f_id = "f_id"
        const params = {
          // headers : { 'Authorization': sessionStorage.token },
          f_id : onID,  //父节点ID
          org_type : this.addInstitutionForm.value,    //类型
          name : this.addInstitutionForm.institution_name,     //全称
          org_name : this.addInstitutionForm.institution_qname,   //简称
          org_info : this.addInstitutionForm.institution_info,
        }
        await this.$http.post('api/user/organization/',params).then(res => {
          if(res.data.code === 200) {
            this.$message.success( res.data.msg )
          }
          else{
            console.log(res.data.msg)
            this.$message.success( res.data.code + res.data.msg )
          }
        }).catch(err => {
          this.$message.error(err)
          console.log(err)
        })
      },
