<body>
<div id="app">
<div class="tab_box">
<! - loop tab header (item, index) item for the variable name index for the index @ click = "tabClick (index)" setting Click event passed in the index because the only index that is controlled only: class = "? num == index 'active': ''" triplet of expressions to satisfy the conditions to add the class name does not satisfy not add ->
<div v-for ="(item,index) in list" class="tab" @click="tabClick(index)" :class = "num==index? 'active':''">
{{item.name}}
</div>
</div>
<div class="tab_content">
<-! V-if = "num == index" which is initialized to 0 num tabs body definition is to make the first display additional deletion here of course also be used v-show effect is the same, but need to be addressed css because v-show he is accounted location ->
<div class="tab_content_item" v-for ="(item,index) in list" v-if = "num==index">
I am interested in {{item.age}} is {{item.hobby}}
</div>
</div>
</div>
</body>
<script>
new view ({
the '#app'
data: {
// write data list only one, according to the requirements tab tab head and body may be two objects, the same principle
list : [
{Name: 'Bob', age: 23, hobby: 'fight'},
{Name: 'small strong', age: 25, hobby: 'basketball'},
{Name: 'Xiaopeng', age: 23, hobby: 'comic'},
{Name: 'Li', age: 23, hobby: 'sleep'},
{Name: 'Betty', age: 23, hobby: 'smug'}
],
// define the initial lower standard style that is initialized to show the page
a: 0
},
methods:{
// Set the click event is received index
tabClick:function(index){
console.log(index)
// m-per-click when reassigned num
this.num = index
}
}
})
</script>
</html>

If you really do not understand you can copy the code to run it, hands is the last word
