专栏目标
在vue和element UI联合技术栈的操控下，本专栏提供行之有效的源代码示例和信息点介绍，做到灵活运用。
（1）提供vue2的一些基本操作：安装、引用，模板使用，computed，watch，生命周期(beforeCreate，created,beforeMount，mounted, beforeUpdate，updated, beforeDestroy，destroyed，activated，deactivated，errorCaptured，components，)、 $root , $parent , $children , $slots , $refs , props, $emit , eventbus ,provide / inject, Vue.observable, $listeners, $attrs, $nextTick , v-for, v-if, v-else,v-else-if，v-on，v-pre，v-cloak，v-once，v-model， v-html, v-text, keep-alive，slot-scope， filters, v-bind，.stop, .native, directives，mixin，render，国际化，Vue Router等
（2）提供element UI的经典操作：安装，引用，国际化，el-row，el-col，el-button，el-link，el-radio，el-checkbox ，el-input，el-select, el-cascader, el-input-number, el-switch,el-slider, el-time-picker, el-date-picker, el-upload, el-rate, el-color-picker, el-transfer, el-form, el-table, el-tree, el-pagination,el-badge,el-avatar,el-skeleton, el-empty, el-descriptions, el-result, el-statistic, el-alert, v-loading, $message, $alert, $prompt, $confirm , $notify, el-breadcrumb, el-page-header,el-tabs ,el-dropdown,el-steps,el-dialog, el-tooltip, el-popover, el-popconfirm, el-card, el-carousel, el-collapse, el-timeline, el-divider, el-calendar, el-image, el-backtop，v-infinite-scroll， el-drawer等
应用场景
vue采用数据驱动，不对dom进行操作。 有的时候为了控制屏幕的宽高度等，需要引入jquery来进行处理。如何配置呢？
package.json 配置
"dependencies": {
"axios": "^0.19.0",
"core-js": "^3.4.4",
"echarts": "^4.8.0",
"element-ui": "^2.13.0",
"jquery": "^3.4.1",
"ol": "^6.1.1",
"qs": "^6.9.4",
"screenfull": "^5.0.2",
"vue": "^2.6.10",
"vue-i18n": "^8.15.3",
"vue-router": "^3.1.3",
"vuex": "^3.1.2"
},
vue.config.js配置
const CopyWebpackPlugin = require('copy-webpack-plugin')
const webpack = require('webpack')
const path = require('path')
const debug = process.env.NODE_ENV !== 'production'
module.exports = {
configureWebpack: {
resolve: {
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': path.resolve('src')
}
},
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"windows.jQuery": "jquery"
}),
],
},
pluginOptions: {
'style-resources-loader': {
preProcessor: 'less',
patterns: [path.resolve(__dirname, "src/css/index.less")]
}
}
}
main.js配置
import $ from ‘jquery’
配置完后就可以在项目中使用$l了。
