1 <el-dialog 2 :title="vedioEditFrom.id ? '编辑视频文件' : '添加视频文件'" 3 :visible.sync="dialogEditVisible" 4 width="700px" 5 :close-on-click-modal="false" 6 :before-close="closeBefore" 7 > 8 <el-form :model="vedioEditFrom" ref="vedioEditFrom" :rules="rules"> 9 <el-form-item label-width="140px" label="视频标题 : " prop="vdTitle"> 10 <el-input v-model="vedioEditFrom.vdTitle" placeholder="请输入视频标题"></el-input> 11 </el-form-item> 12 <el-form-item v-if="!vedioEditFrom.id" label-width="140px" label="存储至 : " prop="ClassId"> 13 <el-cascader :props="props" v-model="vedioEditFrom.ClassId"></el-cascader> 14 </el-form-item> 15 <el-form-item v-if="listQuery.vb_id" label-width="140px" label="所属视频 : "> 16 <el-tag class="filter-item" closable @close="deleteTag">{{ vb_name }}</el-tag> 17 </el-form-item> 18 <el-form-item v-if="!vedioEditFrom.id" label-width="140px" label="视频封面图片 : " prop="coverFile"> 19 <el-upload 20 class="avatar-uploader" 21 action="fakeaction" 22 ref="upCoverImg" 23 :auto-upload="false" 24 :show-file-list="true" 25 :disabled="isUpImgDisabled" 26 accept=".jpg,.jpeg,.png,.JPG,.JPEG" 27 :on-change="UpdataImgFileChange" 28 list-type="picture-card" 29 > 30 <i v-if="!vedioEditFrom.coverFile" class="el-icon-plus avatar-uploader-icon"></i> 31 <div slot="file" slot-scope="{ file }"> 32 <img class="el-upload-list__item-thumbnail" :src="file.url" alt="" /> 33 <span class="el-upload-list__item-actions"> 34 <span class="el-upload-list__item-delete" @click="cover_imgRemove()"><i class="el-icon-delete"></i></span> 35 </span> 36 </div> 37 <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过2MB</div> 38 </el-upload> 39 </el-form-item> 40 <el-form-item v-if="!vedioEditFrom.id" label-width="140px" label="视频文件 : " prop="mediaFile"> 41 <el-upload 42 class="radio-btn" 43 ref="upVedio" 44 action="fakeaction" 45 :auto-upload="false" 46 :show-file-list="true" 47 :disabled="isUpVedioDisabele" 48 :file-list="vedioFiles" 49 accept=".mp4,.avi,.wmv,.mpeg,.m4v,.mov,.asf,.flv,.f4v,.rmvb,.rm,.3gp,.vob" 50 :on-change="vedioFileChange" 51 list-type="text" 52 > 53 <el-button slot="trigger" size="small" type="primary" :disabled="isUpVedioDisabele">选取文件</el-button> 54 <el-button size="small" type="danger" @click="vedioRemove" v-show="isUpVedioDisabele">删除</el-button> 55 56 <div slot="tip" class="el-upload__tip">只能上传mp4,avi,wmv,mpeg,m4v,mov,asf,flv,f4v,rmvb,rm,3gp,vob文件，且不超过2000MB</div> 57 </el-upload> 58 </el-form-item> 59 <el-form-item label-width="140px" label="视频作者 : " prop="vdAuthor"> 60 <el-input v-model="vedioEditFrom.vdAuthor" placeholder="请输入视频作者"></el-input> 61 </el-form-item> 62 <el-form-item label-width="140px" label="视频介绍 : " prop="vdIntroduce"> 63 <d2-quill style="min-height: 200px; margin-bottom: 20px;" v-model="vedioEditFrom.vdIntroduce" /> 64 </el-form-item> 65 <el-form-item label-width="140px" label="排序 : " prop="sort"> 66 <el-input-number v-model="vedioEditFrom.sort" :min="1" label="请输入排序"></el-input-number> 67 </el-form-item> 68 69 <el-form-item label-width="140px" label="发布日期 : " prop="publicDate"> 70 <el-date-picker v-model="vedioEditFrom.publicDate" value-format="yyyy-MM-dd HH:mm:ss" type="datetime" placeholder="选择日期时间"></el-date-picker> 71 </el-form-item> 72 <el-form-item label-width="140px" label="视频试看秒数 : " prop="vdSeeSeconds"> 73 <el-input v-model.number="vedioEditFrom.vdSeeSeconds" placeholder="请输入视频试看秒数" type="Number"></el-input> 74 </el-form-item> 75 <el-form-item label-width="140px" label="虚拟播放次数 : " prop="playSumVirtual"> 76 <el-input-number v-model="vedioEditFrom.playSumVirtual" :min="0" label="请输入虚拟播放次数"></el-input-number> 77 </el-form-item> 78 <!-- <el-form-item label-width="140px" label="是否启用 : " prop="delStatus"> 79 <el-switch v-model="vedioEditFrom.delStatus" active-text="启用" inactive-text="未启用" :active-value="1" :inactive-value="2"></el-switch> 80 </el-form-item> --> 81 <el-form-item label-width="140px" label="是否免费 : " prop="vdIsfree"> 82 <el-switch v-model="vedioEditFrom.vdIsfree" active-text="是" inactive-text="否" :active-value="2" :inactive-value="1"></el-switch> 83 </el-form-item> 84 <el-form-item label-width="140px" label="备注 : " prop="remark"> 85 <el-input type="textarea" :rows="2" placeholder="请输入视频介绍" maxlength="60" show-word-limit v-model="vedioEditFrom.remark"></el-input> 86 </el-form-item> 87 </el-form> 88 <div slot="footer" class="dialog-footer"> 89 <el-button @click="cancel">取 消</el-button> 90 <el-button type="primary" v-if="vedioEditFrom.id" :loading="btnLoading" @click="submitUpload">确 定</el-button> 91 <el-button type="primary" v-else :loading="btnLoading" @click="addVedioFile">添 加</el-button> 92 </div> 93 </el-dialog>
第四步 上传文件
