异步组件加载
首先准备-----简单的框架搭出来
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <title>异步组件加载</title> <meta name="viewport" content="width=device-width ,initial-scale=1"> <script src="https://cdn.jsdelivr.net/npm/vue"></script> </head> <body> <div id="app"> <App></App> </div> <script> const App={ data(){ return{ msg:'异步组件加载' } }, template:`<div>{{msg}}</div>`, }; let app = new Vue({ el:'#app', template:``, components:{ App } }) </script> </body> </html>
在新建一个Text.js文件
export default { data() { return { msg: '小朋友' } }, template: `<div>{{msg}}</div>`, }
总代码
1. 里面标签的改变
2.刚开始只有vue.js的加入 在点击之后 Text.js被加载
3.要用一个工厂函数

<script type="module">
const App = {
data() {
return {
isShow:false
}
},
methods:{
asyncLoad(){
this.isShow = !this.isShow
}
},
template: `<div>
<button @click="asyncLoad">异步组件加载</button>
<Test v-if="isShow"></Test>
</div>`,
components: {
Test:()=>import('./Test.js') // 工厂函数 import导入
}
};
let app = new Vue({
el: '#app',
template: ``,
components: {
App
}
})
</script>
</body>
