在使用el-popover和el-radio-group实现弹窗选择数据后调用el-popover的doClose()方法时一直报错！
经过分析发现el-popover及el-radio__original有aria-hidden属性，具体aria-hidden属性应用自行搜索了解。既然是这个玩意引起的，则在显示时将aria-hidden属性移除掉即可：
<div class="flex-row l-flex l-hover" style="position: relative;" :class="{ 'nl-flex': relative == 'or' }"><el-popover placement="bottom" ref="refPop" width="80" trigger="hover" class="h-100 flex-row"popper-class="pop-grid-view" @show="popshow"><el-radio-group v-model="radio" @input="radioChanged"><el-radio :label="item.value" v-for="item in optionsList">{{ item.label }}</el-radio></el-radio-group><el-image slot="reference" style="width: 20px; height: 20px":src="require('@/assets/images/sameR.png')"></el-image></el-popover><el-image class="m-view" :src="require('@/assets/images/downArrow.png')"></el-image></div>给el-popover添加@show="popshow"方法，显示后移除相应的属性！
popshow() {var ariaEls = document.querySelectorAll('.el-popover')ariaEls.forEach((item) => {item.removeAttribute('aria-hidden')})ariaEls = document.querySelectorAll('.el-radio__original')ariaEls.forEach((item) => {item.removeAttribute('aria-hidden')})},
世界一下子干净了好多
