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>
		<li class="li4">
			{{flow.val3}}
		</li>			
	</ul>
