快速上手Element UI 库

2017-11-15  本文已影响748人  九旬大爷的梦

Element UI 是一套采用 Vue 2.0 作为基础框架实现的组件库，一套为开发者、设计师和产品经理准备的基于 Vue 2.0 的组件库，提供了配套设计资源，帮助你的网站快速成型.

一颗星星表示一种模板 我们则使用最后一种模板:webpack-simple模板

下面打对勾则表示下载完成.然后你会发现你的element-ui里多了一个node_modules文件就对了

如果觉得上面步骤没错就是不自动打开浏览器可以手动在浏览器了输入http://localhost:8080/也可以出来.

{
  "name": "element-starter",
  "scripts": {
    "dev": "cross-env NODE_ENV=development webpack-dev-server --inline --hot --port 8086",
    "build": "cross-env NODE_ENV=production webpack --progress --hide-modules"
  },
  "dependencies": {
    "element-ui": "^1.0.0",
    "vue": "^2.1.6"
  },
  "devDependencies": {
    "babel-core": "^6.0.0",
    "babel-loader": "^6.0.0",
    "babel-preset-vue-app": "^1.2.0",
    "cross-env": "^1.0.6",

  }
}

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    loaders: [
      {
        test: /\.vue$/,
        loader: 'vue-loader'
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        loader: 'style-loader!css-loader'
      },
      {
        test: /\.(eot|svg|ttf|woff|woff2)(\?\S*)?$/,
        loader: 'file-loader'
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?\S*)?$/,
        loader: 'file-loader',
        query: {
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true
  },
  devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ])
}

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-default/index.css'
import App from './App.vue'

Vue.use(ElementUI)

new Vue({
  el: '#app',
  render: h => h(App)
})

至此我们的便完成了 Element 的引入.后续只需要修改element-ui>src>App.vue中的内容即可实现相应的组件效果.
比如我们做一个由Element 提供的走马灯效果,只需要修改element-ui>src>App.vue中的内容.代码如下:

<template>
  <div id="app">
    <template>
  <el-carousel :interval="4000" type="card" height="200px">
    <el-carousel-item v-for="item in 6" :key="item">
      <h3>{{ item }}</h3>
    </el-carousel-item>
  </el-carousel>
</template>
  </div>
</template>

<script>
export default {
  name: 'app',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}

.el-carousel__item h3 {
    color: #475669;
    font-size: 14px;
    opacity: 0.75;
    line-height: 200px;
    margin: 0;
  }
  
  .el-carousel__item:nth-child(2n) {
    background-color: #99a9bf;
  }
  
  .el-carousel__item:nth-child(2n+1) {
    background-color: #d3dce6;
  }
</style>

这个错误是因为我们用的Element UI却还没有下载Element UI 的文件.所以我去那个黑框框按下ctrl+c.注意是按下ctrl键+c键.表示重启命令行.重启后即可重新输入命令

这样则表示下载完成.然后我们在输入cnpm run dev启动虚拟服务器即可弹出浏览器页面,(如果输完没有弹出也不要着急).打开你的浏览器输入网址//localhost:8086/,也是可以一样打开的.

具体的服务器的网址以你的黑框框显示的为准,在浏览器中输入正确打开即可看到:
