1. 引用vue.js
<!DOCTYPE html> <html> <head> <script src="http://vuejs.org/js/vue.js"></script> <meta charset="utf-8"> <title>JS Bin</title> </head> <body> <div id="root"> <input type="text" v-model="inputValue"> <button @click="handlerAdd">提交</button> <ul> <li v-for="(item,index) of lists" :key="index" @click="handlerDel(index)" > {{item}} </li> </ul> </div> <script> new Vue({ el: '#root', data: { inputValue: '', lists: [] }, methods: { handlerAdd: function() { this.lists.push(this.inputValue); this.inputValue = ''; }, handlerDel: function(index) { this.lists.splice(index, 1); } } }); </script> </body> </html>
2. 全局组件注册
<!DOCTYPE html> <html> <head> <script src="http://vuejs.org/js/vue.js"></script> <meta charset="utf-8"> <title>JS Bin</title> </head> <body> <div id="root"> <input type="text" v-model="inputValue"> <button @click="handlerAdd">提交</button> <ul> <todo-item v-for="(item,index) of lists" :content = "item" :index = "index" :key = "index" @delete="handlerDel" > </todo-item> </ul> </div> <script> Vue.component('todoItem', { props: { content: String, index: Number }, template: '<li @click="handlerClick">{{content}}</li>', methods: { handlerClick: function(){ this.$emit('delete', this.index); } } }); new Vue({ el: '#root', data: { inputValue: '' , lists: [] }, methods: { handlerAdd: function() { this.lists.push(this.inputValue); this.inputValue = ''; }, handlerDel: function(index) { this.lists.splice(index,1); } } }); </script> </body> </html>
3. vue-cli脚手架
// Todo.Vue <template> <div> <input type="text" v-model="inputValue"> <button @click="handlerAdd">提交</button> <ul> <todo-item v-for="(item,index) of lists" :key="index" :content="item" :index="index" @delete="handlerDel" ></todo-item> </ul> </div> </template> <script> import TodoItem from './components/todoItem' export default { data () { return { inputValue: '', lists: [] } }, methods: { handlerAdd () { this.lists.push(this.inputValue) this.inputValue = '' }, handlerDel (index) { this.lists.splice(index, 1) } }, components: { 'todo-item': TodoItem } } </script> <style> </style> // TodoItem.vue <template> <li @click="handlerClick" class="item">{{content}}</li> </template> <script> export default { props: ['content', 'index'], methods: { handlerClick () { this.$emit('delete', this.index) } } } </script> <style scoped> ul,li { list-style: none; } .item { color: blueviolet; } </style>
