Vue3 + elementplus实现表单验证+上传图片+ 防止表单重复提交功能
首先,上官网地址
首先页面上面用了弹窗的形式,做完之后长这样,有全屏,关闭等按钮,上效果图和完整代码!!!!!
<!--点击新增按钮 --> <div class="addbtn" @click="fundOperation()"> <span>+</span> 新增 </div> <el-dialog v-model="datadialog" :show-close="true" :close-on-click-modal="false" width="746px" :title="dialogtitle" :fullscreen="fullscreen" :destroy-on-close="true" @close="closeDialog" > <!--是否全屏--> <div class="fullicon" @click="fullscreen = !fullscreen"> <img src="../../assets/info_open.png" alt=""></div> <div class="box-title"> <img src="../../assets/info_basic.png" alt=""> <span>基本信息</span> </div> <el-form :model="ruleForm" :rules="rules" label-width="120px" label-position="right" class="demo-ruleForm" :size="formSize" ref="ruleFormRef" > <el-form-item label="标题" prop="title"> <el-input v-model="ruleForm.title" placeholder="请输入80个字符以内标题" :clearable="true" label-width="100%" maxlength="80" autocomplete="off" /> </el-form-item> <el-form-item prop="img" class="upload" label="上传图片" v-loading="loading" > <el-upload class="upload-demo" :limit="1" action="/api/v1/upload/file" name="multipartFile" :on-success="uploadSucceed" :on-error = "uploadError" :file-list="fileList" list-type="picture" :before-upload="beforeUpload" :on-remove="fileRemoved" accept=".jpg,.jpeg,.png,.JPG,.JPEG" ref="upload" > <el-button size="small" type="primary">点击上传</el-button> </el-upload> <div class="el-upload__tip">图片尺寸:600*200,图片5MB以内,图片格式支持JPG、JPEG、PNG</div> </el-form-item> <!-- 是否推荐 0不推荐 1推荐--> <el-form-item prop="recommend" label="是否推荐" > <el-select v-model="ruleForm.recommend" placeholder="请选择是否推荐" > <el-option label="是" :value="1" ></el-option> <el-option label="否" :value="0" ></el-option> </el-select> </el-form-item> <el-form-item label="特殊资源" prop="share"> <el-radio-group v-model="ruleForm.share"> <el-radio label="线上品牌商赞助"></el-radio> <el-radio label="线下场地免费"></el-radio> </el-radio-group> </el-form-item> <el-form-item label="活动性质" prop="type"> <el-checkbox-group v-model="ruleForm.type"> <el-checkbox label="美食/餐厅线上活动" name="type"></el-checkbox> <el-checkbox label="地推活动" name="type"></el-checkbox> <el-checkbox label="线下主题活动" name="type"></el-checkbox> <el-checkbox label="单纯品牌曝光" name="type"></el-checkbox> </el-checkbox-group> </el-form-item> <el-form-item label="活动形式" prop="content"> <el-input type="textarea" v-model="ruleForm.content"></el-input> </el-form-item> </el-form> <template #footer> <span class="dialog-footerData" > <!-- 当使用指令方式时,全屏遮罩需要添加fullscreen修饰符(遮罩会插入至 body 上),此时若需要锁定屏幕的滚动,可以使用lock修饰符;当使用服务方式时,遮罩默认即为全屏,无需额外设置。--> <el-button class="bai" @click="dataCancel" >取消</el-button> <el-button type="primary" @click="dataConfirm(1)" v-loading.fullscreen.lock="fromloading">发布</el-button> </span> </template> </el-dialog>
表单校验 和数据提交
