JS中以变量方式访问对象属性

this.enterprise[val]
如

search(){
	this.$api.enterpriseDetail(this.params).then(res=>{
		this.enterprise = res.data
		const basicInfo = ["shareholders","branches","majorMember","stocksinfos","changerecords"]
		basicInfo.forEach((val,index,arr)=>{
			if(this.enterprise[val] && this.enterprise[val] != null){
				this.info[0].content[index + 1].flag = true
			}
		})
	})
}
