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
需求背景
在vue项目开发中,涉及到流量的使用情况,采用el-progress进度条来显示目前流量的状态。由于流量是越来越少,所以要采用逆向的方式来显示出来。el-progress示例中都是正向的方式,我们这里是做了一小部分修改,达到了想要的效果,如图。

>>>.el-progress-bar{ margin-bottom:20px;}

核心代码
解决问题的办法,就是修改el-progress的样式,left: auto;right: 0; 这是核心文章来源地址https://www.toymoban.com/news/detail-703077.html
>>>.el-progress-bar__inner{text-align: right;left: auto;right: 0; border: 1px solid #fff;}
