基本结构
<!DOCTYPE html> <html lang="zh"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>网页</title> </head> <body> </body> </html>
引入vue3
... <script src=" ...
使用vue3
具体vue3语法请看官网
注意：setup语法糖，无法在html里面使用，请使用 setup() 函数 去处理！
<!-- 不支持 --> <script setup> // doingsthing </script>
上面是错误写法
<!-- 正确用法 -->
...
<body>
<div id="app"></div>
</body>
...
<script>
const { createApp } = Vue
const APP = createApp({
setup(){}
})
APP.mount('#app')
</script>
使用UI框架
这里以element-plus为例
引入
... <!-- 全局样式 --> <link rel="stylesheet" href="https://unpkg.com/element-plus/dist/index.css" /> <!-- UI --> <script src="https://unpkg.com/element-plus"></script> ...
基本使用
...
<div id="app">
<el-input v-model="value" clearable />
</div>
...
<script>
const { createApp, ref } = Vue
const APP = createApp({
setup(){
const value = ref(null)
return {
value
}
}
})
APP.use(ElementPlus).mount('#app')
</script>
交互
...
<div id="app">
<el-button type="primary" @click="handle">提示</el-button>
</div>
...
<script>
const { createApp, ref } = Vue
const APP = createApp({
setup(){
const handle = () => {
ElementPlus.ElMessage({
message: '点击！',
type: 'success',
})
}
return {
handle
}
}
})
APP.use(ElementPlus).mount('#app')
</script>
使用组件
...
<script src="//unpkg.com/@element-plus/icons-vue"></script>
...
<div id="app">
<el-button icon="edit" type="primary" @click="handle">提示</el-button>
</div>
...
<script>
const { createApp, ref } = Vue
const APP = createApp({
setup(){
const handle = () => {
ElementPlus.ElMessage({
message: '点击！',
type: 'success',
})
}
return {
handle
}
}
})
APP.component('edit',ElementPlusIconsVue.Edit)
APP.use(ElementPlus).mount('#app')
</script>
发送请求
... <script src="https://unpkg.com/axios/dist/axios.min.js"></script> ... <script> ... axios.post(url,options } ... </script>
