3 效果展示

4 总结

4.1 默认显示指定条数的v-for列表循环

   1:循环的时候就通过使用过滤器控制显示的条数 2：点击"more"时让控制条数的变量等于数组总长度

4.2 点击的某个循环列表指定样式  .xxx

   1: 先定义一个变量 currentIndex:0;   2:@click="currentIndex=index"; 3:.class="{'xxx':currentIndex==index}"

4.3 点击设为“默认地址”，其他变为“设为默认”

   1：将当前的列表的索引index传递过去 2：js代码中便利所有数组，将与传来的index与数组的index比较，index(页面)==index（数据）时设为默认，其他设为非默认

4.4 非循环出来的列表控制选中效果和非选中效果

  1：初始一个变量 xxx:1 2:列表1：  :class="{'类名':xxx==1}" @click="xxx=1"、  列表2： :class="{'类名':xxx==2}" @click="xxx=2"
