最近在学习VUE,目前酸菜鱼也才刚开始几天,或许是没天赋之前接触框架也很浅显,很多稍难地方学习的不通透,简单的反倒一过就忘记了。于是想要把简单基础逐步简单梳理一遍,以防万一自己连基础的都学不到,分享给大家共同总结学习。
v-for的四种应用方式:
方式一:v-for循环普通数组
//土蛋方法: <p>{{list[0]}}</p> <p>{{list[1]}}</p> <p>{{list[2]}}</p> <p>{
{list[3]}}</p> <p>{{list[4]}}</p> //v-for方法: <p v-for="(item,i) in list">{{i}},{
{item}}</p> //数组数据部分: data:{ list:[1,2,3,4,5,6] },
方式二:v-for循环对象数组
//v-for用法: <p v-for="(user,i) in list">{{user.id}},{{user.name}},{{i}}</p>
//数组数据部分: list:[ {id:1,name:"zs1"}, {id:2,name:"zs2"}, {id:3,name:"zs3"},
{id:4,name:"zs4"}, ]
方式三:v-for循环对象
注意:在遍历对象身上的键值对的时候,除了有 val key,在第三个位置还有一个索引值
//v-for方法 <p v-for="(val,key,i) in user">{{val}},{{key}}</p> //对象部分: user:{
id:1, name:"巧克力" gender:"萌妹" }
方式四:v-for迭代数组
//in后面我们放过 普通数组 对象数组 对象 还可以放数字 //注意:如果使用 v-for 迭代数字的话,前面的count值从1开始 <p
v-for="count in 10">这是第{{count}}次循环</p>
