这篇文章我们将使用组件化的思想来修改一下，之前实现的TodoList功能
全局化组件的实现方式：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>TodoList</title>
<script src="./vue.js"></script>
</head>
<body>
<div id="app">
<input type="text" v-model="inputTxt">
<button @click="submitEvent">提交</button>
<ul>
<todo-item v-bind:content="list" v-for="list in todoList" ></todo-item><!--向子组件传递绑定值 -->
</ul>
</div>
<script>
//创建全局组件
Vue.component('TodoItem',{
props:['content'],//接受传递的值
template:`<li>{{this.content}}</li>`
})
var app = new Vue({
el: '#app',
data:{
inputTxt:'',
todoList: []
},
methods:{
submitEvent: function(){
this.todoList.push(this.inputTxt);
this.inputTxt = '';
}
}
})
</script>
</body>
</html>
我们还可以使用子组件的方式：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>TodoList</title>
<script src="./vue.js"></script>
</head>
<body>
<div id="app">
<input type="text" v-model="inputTxt">
<button @click="submitEvent">提交</button>
<ul>
<todo-item v-bind:content="list" v-for="list in todoList" ></todo-item>
</ul>
</div>
<script>
//子组件
let TodoItem = {
props:['content'],
template:`<li>{{this.content}}</li>`
};
var app = new Vue({
el: '#app',
data:{
inputTxt:'',
todoList: []
},
methods:{
submitEvent: function(){
this.todoList.push(this.inputTxt);
this.inputTxt = '';
}
},
components:{
TodoItem: TodoItem
}
})
</script>
</body>
</html>
