本文主要是介绍【已解决】引用官网的 Element-Message 消息框居然报错为什么呢?,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
vue 版本 : vue3
编程语言:JavaScriptos: macos13
组件 :element-plus
问题组件: Message 信息框
问题:想学习使用 element 官网里的组件,我找到了message
消息提示,然后我就把代码复制下来放到创建好的 app.vue中的组件中,结果报一堆错误。 吓人这么一堆看都看不懂官网示例代码:
<template><el-button :plain="true" @click="open1">Success</el-button><el-button :plain="true" @click="open2">Warning</el-button><el-button :plain="true" @click="open3">Message</el-button><el-button :plain="true" @click="open4">Error</el-button>
</template><script lang="ts" setup>
import { ElMessage } from 'element-plus'const open1 = () => {ElMessage({message: 'Congrats, this is a success message.',type: 'success',plain: true,})
}
const open2 = () => {ElMessage({message: 'Warning, this is a warning message.',type: 'warning',plain: true,})
}
const open3 = () => {ElMessage({message: 'This is a message.',type: 'info',plain: true,})
}
const open4 = () => {ElMessage({message: 'Oops, this is a error message.',type: 'error',plain: true,})
}
</script>
解决方案:
其实这是 webpack 编译的错误,因为无法识别ts 文件,全程是 typescript ,我们只需要把 ts 代码改为 js 即可,修改好的代码:
<template><el-button :plain="true" @click="open1">Success</el-button><el-button :plain="true" @click="open2">Warning</el-button><el-button :plain="true" @click="open3">Message</el-button><el-button :plain="true" @click="open4">Error</el-button>
</template><script setup>
import { ElMessage } from 'element-plus'const open1 = () => {ElMessage({message: 'Congrats, this is a success message.',type: 'success',plain: true,})
}
const open2 = () => {ElMessage({message: 'Warning, this is a warning message.',type: 'warning',plain: true,})
}
const open3 = () => {ElMessage({message: 'This is a message.',type: 'info',plain: true,})
}
const open4 = () => {ElMessage({message: 'Oops, this is a error message.',type: 'error',plain: true,})
}
</script>
到这里就结束了,只是简单的语法识别错误,只需要改为 js 即可。
