vue.js v-for group rendering
I want to implement a list of mobile phone contacts. And group by initial letter. How to use v-for in vue to render?
HTML template
<li v-for="(item,index) in carbrands">
<h2 class="list-title" v-show="" >{{item.LETTER}} {{index}}</h2>
<ul class="list-content">
<li class="list-car-item" @click="typeShow"><img :src="item.IMAGE" alt=""><span>{{item.NAME}}</span></li>
</ul></li>
data
The effect you want to achieve through the LETTER in the data
I am a rookie, please advise.
Vue 1.0 directly uses OrderBy to sort the first letter
<v-for="(item,index) in carbrands | orderBy'LETTER'">
// The first in the array displays LETTER and Letter in the current array element! = Letter in the previous array element is displayed.
v-show="index === 0 || item.LETTER !== carbrands[index-1].LETTER"
Vue 2.0 uses calculated properties
<v-for="(item,index) in carbrands">
v-show="index === 0 || item.LETTER !== carbrands[index-1].LETTER"
computed: {
carbrands: function () {
return _.orderBy(this.carbrands,'LETTER');
}
}
Warm suggestion: When asking questions, directly post the code to facilitate others to copy and paste and modify, it is very inconvenient for you to post pictures
