使用vue点击li,获取当前点击li父辈元素的属性值方法

<div class="content">		<!-- change方法, 数值改变触发 -->	<select v-on:change="getData()" name="" id="dataSelect">		<option value="" v-bind:name="index" v-for="(value, index) in items">{{value.date}}</option>	</select>			  	<!-- 为name属性添加当前索引值 -->	<ul v-on:click="toFlow($event)" v-bind:name="i" class="flowData" v-for="(flow, i) in flows">		<li class="li1">			{{flow.name.fullName}}<br>			{{flow.name.time}}		</li>			<li class="li2">			{{flow.val1}}		</li>		<li class="li3">			{{flow.val2}}		</li>		<li class="li4">			{{flow.val3}}		</li>				</ul>		 </div>

<script>	var vm = new Vue({		el: "#app",		data: {			user: {},			items: [],			flows: []		},		methods: {			// 根据option数值替换数据			getData: function() {				var optionIndex = $('#dataSelect option:selected').attr("name"); //选中的值				vm.flows = vm.items[optionIndex].flowsMonth;			},			toFlow: function(event) {				// 点击li获取当前li父辈ul的name属性值				var flowIndex = event.target.parentNode.getAttribute("name");				var flow = (vm.flows[flowIndex]);				$.ajax({					url: 'php/test.php',					type: 'POST',					dataType: "json",					data: {						flow: flow					},					success: function(data) {						console.log(data);					}				})				}		}	}) 	$(function(){		$.ajax({			url: 'json/items.json',			type: 'GET',			dataType: "json",			success: function(data) {				vm.user = data.user;				vm.items = data.flows;				// 初始数据				vm.flows = vm.items[0].flowsMonth;			}		})		})</script>
