這篇文章主要講解了“html頁面引入vue組件之http-vue-loader.js方法怎么用”，文中的講解內容簡單清晰，易于學習與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學習“html頁面引入vue組件之http-vue-loader.js方法怎么用”吧！
首先這種方法不推薦，日常工作中也不會在html里面引入一個vue文件，只是為了有時候方便測試才會這么做
1.創建my-component.vue
<template>
<div class="hello">Hello {{who}}</div>
</template>
<script>
module.exports = {
data: function() {
return {
who: 'world'
}
}
}
</script>
<style>
.hello {
background-color: #ffe;
}
</style>2.創建index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- 引入樣式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css" rel="external nofollow" >
<!-- 先引入 Vue -->
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<!-- 引入 http-vue-loader -->
<script src="https://unpkg.com/http-vue-loader"></script>
</head>
<body>
<div id="app">
<my-component></my-component>
</div>
</body>
<!-- 引入組件庫 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
<script>
// 使用httpVueLoader
Vue.use(httpVueLoader);
new Vue({
el: '#app',
data: function () {
return { visible: false }
},
components: {
// 將組建加入組建庫
'my-component': 'url:./component/my-component.vue'
}
})
</script>
</html>這樣就可以直接在html頁面里面引用vue文件，而不需要從頭開始創建一個新的vue項目，方便日常測試使用
httpVueLoader的其他組件載入方式可查看這里
主要是最近寫的項目涉及到,就順便記錄一下,
使用的概率不是很大啊畢竟現在大部分都是直接搭的項目組件正常方式使用組件即可
既然是單頁面使用,最簡單快捷的就是直接script引用了,這里我就直接把文件放出來自取好了,今天百度網盤有點卡分享不出來,文件又比較長,就放文章最末尾吧
<script src="./lib/httpVueLoader.js" type="text/javascript" charset="utf-8"></script>
隨便畫個組件反正也就測試用用
<template>
<div class="test">
<p>{{name}}</p>
<p>{{state}}</p>
</div>
</template>
<script>
module.exports = {
name:'test',
data(){
return{
name:222
}
},
props:{
state:{
type:String
}
}
}
</script>
<style>
</style>引用方法有好幾種 這里我就拿我用的來舉例吧,直接上父組件代碼,首先是html頁面
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta name="renderer" content="webkit|ie-comp|ie-stand"> <title></title> <link rel="stylesheet" type="text/css" href="PCdemo/src/js&css/mainPage.css" rel="external nofollow" /> </head> <body> <!-- 容器 --> <div id="mainpage"> <p>這是父組件頁面</p> <!--組件測試 --> <test></test> </div> <!-- vue2.6.11 --> <script src="./lib/vue.js"></script> <!-- 組件測試 --> <script src="./lib/httpVueLoader.js" type="text/javascript" charset="utf-8"></script> <!-- 自定義js --> <script src="PCdemo/src/js&css/mainPage.js" type="text/javascript" charset="utf-8"></script> </body> </html>
然后是js頁面,當然全寫一個html也行啊看個人喜好,這里因為項目需求兼容ie,所以寫的比較原始
var appVue = new Vue({
el: "#mainpage",
components:{
'test': httpVueLoader('../PCdemo/src/components/test.vue')
},
data: function() {
return {
state:'1111'
}
}
})那么效果就完成了
組件官網 還提供了其他注冊引入方法,講的比較細致啊這里就不贅述了 有興趣可以自己去看看
