vue v-for遍历多种使用方式
原创
(1)v-for遍历数组获取数组的item对象的value
采用v-for对数组进行遍历
<ul>
<li v-for="item in names">{{item}}</li>
</ul>
<!DOCTYPE html>
<title>test</title>
<script
type="text/javascript"
src="../../node_modules/vue/dist/vue.js"
></script>
</head>
<div id="app">
<li v-for="item in names">{{item}}</li>
<script type="text/javascript">
const app = new Vue({
el: "#app",
data: {
names: ["james", "curry", "lotus"],
methods: {},
</script>
<style></style>
</body>(2)v-for遍历数组获取数组的item和key
<ul>
<li v-for="(item,key) in names">
<a>item是{{item}}</a>
<a>key是{{key}}</a>
</li>
</ul>
<!DOCTYPE html>
<title>test</title>
<script
type="text/javascript"
src="../../node_modules/vue/dist/vue.js"
></script>
</head>
<div id="app">
<li v-for="(item,key) in names">
<a>item是{{item}}</a>
<a>key是{{key}}</a>
<script type="text/javascript">
const app = new Vue({
el: "#app",
data: {
names: [{"Letter":"A"}, {"Letter":"B"}, {"Letter":"C"}],
methods: {},
</script>
<style></style>
</body>
(3)对象遍历，v-for也可以对单个对象进行遍历
<ul>
<li v-for="(item,key,index) in names">
<a>item是{{item}}</a>
<a>key是{{key}}</a>
<a>index是{{index}}</a>
</li>
</ul>
<!DOCTYPE html>
<title>test</title>
<script
type="text/javascript"
src="../../node_modules/vue/dist/vue.js"
></script>
</head>
<div id="app">
<li v-for="(item,key,index) in names">
<a>item是{{item}}</a>
<a>key是{{key}}</a>
<a>index是{{index}}</a>
<script type="text/javascript">
const app = new Vue({
el: "#app",
data: {
names: {"LetterA":"A","LetterB":"B","LetterC":"C"},
