vue中v-for的用法以及參數的作用

<template>
  <div>
    <div class="content clearfix" v-on:click="goorderingDetail(v)" v-for="(v,index) in anylist" :key="index">
      <div class="clearfix">
        <div class="fl dingnumber">訂單號&nbsp;&nbsp;<span>{{v.orderNum}}</span></div>
        <div class="fr state">{{v.state}}</div>
      </div>
      <div class="clearfix receive">
        <div class="fl">收</div>
        <div class="fr add reAdd">{{v.receiveAdd}}</div>
      </div>
      <div class="clearfix send">
        <div class="fl">發</div>
        <div class="fr add sAdd">{{v.sendAdd}}</div>
      </div>
      <div class="date fl">2018年9月28日&nbsp;&nbsp;&nbsp;&nbsp;12:00</div>
      <div class="fr sure" v-on:click.stop="gosureReceive(v)">確認取件</div>
    </div>
  </div>

上面代碼中，第3行和第17行：

第3行和第17行函數都包含在v-for循環中，參數中傳入的參數v都可以獲取到數據集合

第50和第62行在函數中傳入v即可獲取到對應的值（但是需要在定義函數和使用函數時都傳入參數v才能用）
