14:01:41] waiting for changes... （2）说明， A、编译成功了，正在监听文件改动 B、这不是一个完整的项目 C、编译成功的文件没有index.html文件可供插入3、问题3 （1）现象，[Vue warn]: Invalid prop: custom validator check failed for prop "type". vue.runtime.esm.js? （2）解决， A、这个问题不影响项目的正常运行 B、出现这个报错的原因是，iview支持数字类型的输入，vue自带的-vue错误检查工具-vue.runtime.esm.js-不支持数字类型的输入，因而报错 C、解决方案，开发者应当在浏览器安装-vue错误检查插件-https://github.com/vuejs/vue-devtools，取代vue.runtime.esm.js，给vue检查错误4、问题4，用插件vod-js-sdk-v6上传视频时 来源，https://cloud.tencent.com/developer/ask/260695 （1）现象，报错“Error: ugc upload | signature verify forbidden” （2）原因， A、前端向后台索要签名，后台用小权限“腾讯账户”向腾讯索要签名， B、腾讯给后台小权限签名，后台给前端小权限签名，前端将小权限签名发给腾讯，腾讯给前端报错 （3）解决，让后台换用大权限“腾讯账户”5、问题5 （1）现象，不是第一页的最后一页为空白 （2）原因，最后一页不是第一页，删除最后一页的唯一项，然后请求当前页数据 （3）解决， delModelTrainings({trainingId: row.trainingId}).then(() => { ElMessage.success('删除成功'); var total = (page.value.pageNum - 1)*page.value.pageSize + 1; //当前页情况 //当前页第1项的序号=数据的总数（当前页是最后1页且只有1项） //当前页第1项的序号>每页条数（当前页不是第1页） if(total === page.value.count && total > page.value.pageSize){ page.value.pageNum--; } listData(); })6、问题6 （1）现象，:src 文件路径错误问题的解决方法 （2）解决， <template> <img :src="item.url" alt="logo" /> </template> import background from '@/assets/image/background.png' var collect = reactive([ { url: background, // url: '/src/assets/images/logo.png' 注释这样的写法会出错 teacher: "讲师：李老师", } ]);7、问题7 （1）现象，el-select的blur事件不能通过{trigger:'blur'}触发，只能通过{@blur="selectBlur"}触发 （2）解决， <el-form-item label="所属页卡" prop="card_id" > <el-select v-model="form.card_id" placeholder="请选择所属页卡" @blur="selectBlur"> <el-option v-for="item in configType" :key="item.value" :label="item.label" :value="item.value"> </el-option> </el-select> </el-form-item> rules: {//trigger: 'blur'无效，trigger:

ele.style.height = height + 'px' ele.scrollTo({ top: 0, behavior: 'smooth' }) })6、在初始化时，（元素）滚动条回到底部 （1）html <div class="training-result-code"> <div class="training-result-title"> 训练日志 </div> <div class="training-result-code_content1" ref="divShow"> <div ref="divSonShow"> {{ modelLogs }} </div> </div> <div class="training-result-code_content2" ref="divHide" > {{ modelLogs }} </div> </div> /* 以下弹窗中使用 */ <el-dialog title="查看日志" v-model="dialogVisible" width="70%"> <div class="record-detail-code"> <div class="record-detail-code_content1" ref="divShow"> <div ref="divSonShow"> {{ modelLogs }} <div style="padding-bottom: 100px"></div> </div> </div> <div class="training-result-code_content2" ref="divHide" > {{ modelLogs }} </div> </div> <template #footer> <el-button type="primary" @click="dialogVisible = false">确 定</el-button> </template> </el-dialog> （2）css &-code{ background-color: #fff;

this.$nextTick(() => {//加上这层壳，下面内容在DOM更新后执行 var innerHTML = document.getElementById('divBox').innerHTML; console.log(innerHTML); }) } }, } </script> <style lang="less"></style>7、深度选择器 附、scoped说明 A、尽量不要使用scoped，原因：全局的样式名和本页面的样式名同名时，初次渲染，全局的样式名生效，后续浏览器刷新，本页面的样式名生效 B、替代方案，在本页面最外层用文件名作为样式名，如.app，.app .xxx （1）本页样式 >>> ，原生css支持，sass/less可能无法识别 <style scoped> .wrap >>> .child { color: red; } </style> （2）本页样式 /deep/ ，sass/less可识别，在vue 3.0会报错 <style scoped> .wrap /deep/ .child { color: red; } </style> （3）本页样式 ::v-deep ，vue 3.0支持，编译速度快 <style scoped> .wrap ::v-deep .child { color: red; } </style> （4）示例 <el-date-picker type="date" v-model="queryForm.finishDate" size="small" format="yyyy-MM-dd" placeholder="请选择日期"></el-date-picker> <style scoped lang="scss"> ::v-deep .el-input--small .el-input__inner { height: 30px !important; line-height: 30px !important; } </style> <style scoped> .el-input--small .el-input__inner { height: 30px !important; line-height: 30px !important; } </style> （5）修改elementplus组件的原有样式 路径：右键页面元素-检查-右键标签-Copy-Copy outerHTML 使用：将上述复制结果粘贴到一个空文件里，看层级结构，写选择器 <style lang="scss">//为了解决bug：YANSHOU-10158，本页面此处不要加scoped 2022-2023获奖保密宣传视频合集 .el-upload-list__item-info>.el-progress>.el-progress__text>span{//为了解决bug：http://10.70.38.84/browse/YANSHOU-10158 position: relative;

height: 100px" :src="url" :preview-src-list="srcList"> </el-image> （2）页面“无小图片占位的”预览 <el-image-viewer @close="imgVisible = false" :url-list="[imgSrc]" v-if="imgVisible" /> .el-image-viewer__canvas img{//让图片显示为圆角且描白边 border-radius:10px; border:1px solid #fff } （3）图标-宽固定，高自适应 <svg-icon :icon-class="scope.row.docType" style="font-size: 24px" v-show="scope.row.docType !== 'image'" /> <div style="display: inline-block; width:24px" v-show="scope.row.docType == 'image'"> <img :src="scope.row.publicUrl" style="width: 100%" /> </div>9、拖拽 （1）半途而废案例（正在实现拖拽效果时，需求改变，遂停止） import Sortable from 'sortablejs'; onMounted( function() { const tableBody = document.querySelector('.el-table__body-wrapper tbody'); new Sortable(tableBody, { animation: 150, onEnd: (event) => { const { oldIndex, newIndex } = event; const draggedItem = tableData.value.splice(oldIndex, 1)[0]; tableData.value.splice(newIndex, 0, draggedItem); } }); }); （2）未测试案例（与row、col联合使用，模拟表格） <draggable class="list-group" v-model="tableData" :options="{draggable:'.el-rows'}" :move="getdata" @update="datadragEnd"> <el-row class="el-rows" v-for="(item,index) in tableData" :key="index"> <el-col span="1"> <div class="cell">{{index+1}}</div> </el-col> <el-col span="2"> <div class="cell">{{item.barCode}}</div> </el-col> <el-col span="2"> <div class="cell">{{item.name}}</div> </el-col> <el-col span="2"> <div class="cell">{{item.unit}}</div> </el-col> </el-row> </draggable> （3）不能用案例（与el-table联合使用，百度：vue-draggable、template与el-table联合使用的vue3用法示例） <script setup> import draggable from 'vuedraggable';
