Vue用this.$set赋值数组

日常记录一下Vue用this.$set赋值数组

@select="handleSelectuser($event, index)"

    data: {
        name: '',
        xqarray: [
            {
                "value": "三全鲜食（北新泾店）",
                "address": "长宁区新渔路144号"
            },
            {
                "value": "Hot honey 首尔炸鸡（仙霞路）",
                "address": "上海市长宁区淞虹路661号"
            },
        ],
    },

handleSelectuser(item,index) {
    this.$set(this.data.xqarray[index], 'address', item.user_phone)
},
