Vue整合ElementUI快速开发
出现的问题：
Unknown custom element: <el-input> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
解决办法：
main.js
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui' //element-ui的全部组件
import 'element-ui/lib/theme-chalk/index.css'//element-ui的css
Vue.use(ElementUI) //使用elementUI
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
})
Hello.vue
<template>
<div>
<h1>你好, Hello, {{ name }}</h1>
<el-radio v-model="radio" label="1">备选项1</el-radio>
<el-radio v-model="radio" label="2">备选项2</el-radio>
</div>
</template>
<script>
export default {
data() {
return {
name: "张三",
radio: "2"
};
}
};
</script>
<style>
</style>
当el-table元素中注入data对象数组后，在el-table-column中用prop属性来对应对象中的键名即可填入数据，用label属性来定义表格的列名。可以使用width属性来定义列宽。
vscode添加用户代码片段（快速生成vue模板）
模板
// {
// // Place your 全局 snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and
// // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope
// // is left empty or omitted, the snippet gets applied to all languages. The prefix is what is
// // used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
// // $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders.
// // Placeholders with the same ids are connected.
// // Example:
// // "Print to console": {
// // "scope": "javascript,typescript",
// // "prefix": "log",
// // "body": [
// // "console.log('$1');",
// // "$2"
// // ],
// // "description": "Log output to console"
// // }
// }
