vue 子组件在v-for里如何做到单击某个子组件value+1，其他子组件value-1?
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script type="text/javascript" src="./vue.js"></script>
<title>component-4</title>
</head>
<body>
<h1>component-4</h1>
<hr>
<div id="app">
<child v-for="(value,key) in list"></child>
</div>
<script type="text/javascript">
Vue.component('child',{
template:'<div style="color:red;" @click="setClear">{{value}}</div>',
data:function(){
return {
value:1
}
},
methods:{
setClear:function(){
this.value=0;
}
}
});
var vm=new Vue({
el:'#app',
data:{
list:[
{A:1},
{A:2},
{A:3},
{A:4}
]
},
methods:{
}
})
</script>
</body>
</html>
然后现在要单击对应的子组件做到单击的那个子组件的value+1，其他的value-1
