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项目中,我们需要通过axios获取外部的json文件资源。那么vue组件中如何引用JSON数据呢? 以下是一个示例:

示例效果

在这里插入图片描述

country.json文件

[  
{"name": "Afghanistan", "code": "AF"},  
{"name": "land Islands", "code": "AX"},  
{"name": "Albania", "code": "AL"},  
{"name": "Algeria", "code": "DZ"},
{"name": "Afghanistan", "code": "AF"},  
{"name": "land Islands", "code": "AX"},  
{"name": "Albania", "code": "AL"},  
{"name": "Algeria", "code": "DZ"}
] 

注意啦!最后一个对象后面一定不能添加逗号,否则会报错的
