el-input type="number" 去掉上下箭头 先来看一下原图，会有一个上下箭头::v-deep input { &::-webkit-outer-spin-button, &::-webkit-inner-spin-button { -webkit-appearance: none !important; } }去掉之后

el-upload自定义触发按钮及触发上传前判断 1. 在页面中引用el-upload组件<!-- 自定义按钮div --> <div v-if="routerList.length !== 1" class="action upload" :class="{action_upload_radius: routerList.length === 1}" @click="uploadHandler" > <i class="el-icon el-icon-upload"></i>上传 </div> <!-- hidden upload --> <el-upload v-show="false" class="upload-demo" :action="uploadUrl" :on-success="actionUploadSucc" :show-file-list="false" :headers="headers" :data="actUploadParams" :multiple="false" :file-list="fileList"> <el-button ref="file-home-uploadBtnRef" v-show="false"> <i class="el-icon-upload"></i>上传文件 </el-button> </el-upload>使用一个div模拟一个上传按钮，使用v-show隐藏upload组件，在upload组件的触发按钮el-button上绑定ref2. 触发前条件判断及触发upload上传方式 // action bar 上传btn uploadHandler () { console.log(this.routerList); const len = this.routerList.length if(this.routerList.length === 1) return this.$message.info('请先进入文件夹！') const currFolderId = this.routerList[len-1].folderId // 当前操作的文件夹id this.actUploadParams.folderId = currFolderId // 触发upload组件上传 this.$refs['file-home-uploadBtnRef'].$el.click() },获取到upload触发按钮el-button的ref，在获取到ref上的$el，调用click()自点击触发upload上传
