如何将vue失去焦点事件绑定在当前元素父级标签中的p标签内，因为是循环出来的所以p标签都一样

var vue = new Vue({
        el : "#box",
        data : {
            currentDay: 1,
            currentMonth: 1,
            currentYear: 1970,
            currentWeek: 1,
            days: [],
            pickDay : null,
            currentMemo : null,
            memo_list :["2020-07-24","2020-07-31","2020-08-01"], //时间格式必须为xxxx-xx-xx;
            text:[],
            inputHtml: '<textarea id="duohang" name="a" style="width:114px;height:80px;display: none"></textarea>',
            isShow: false
        },
        created: function() {
            this.initCalendar(null);
        },
        methods:{
            initCalendar: function(cur){
                if (cur) {
                    var date = new Date(cur);
                } else {
                    var date = new Date();

                obj.innerText = e.target.value;

                this.isShow = !this.isShow;

            }


        }
    })

加个index
按我写的改，符号别漏了

v-for="(day, index) in days"
<p :id="'txtdemo' + index"
blur($event, index)

blur:function (e, index) {

                var obj = document.getElementById("txtdemo" + index);

                obj.innerText = e.target.value;

                this.isShow = !this.isShow;

            }

可以用事件委托去实现
