做网站如何应用Java合肥网络推广公司

1、提示

 注意：：：         便利出来的数组   点击保存需要 把 双引号去掉

 this.formData.image = this.imageUrlList.filter((image) => image !== '')

注意：：：    回显的时候需要 再把 双引号加上          

  this.imageUrlList = data.image.split(',')this.imageUrlList.unshift('') //落地页回显

目的是未来  ""  数组的第一项数据 是给 上传使用的    里面有判断   k==0 的时候  显示上传按钮 是添加操作

有时候还需要检测 数组里面是不是只要 一个 空字符串

  if (this.imageUrlList.includes('')) {} else {this.imageUrlList.unshift('') //落地页回显}

2、具体代码如下

   <divv-for="(itemd, k) in imageUrlList"class="qdsng":key="k"style="display: inline-block; position: relative"><!-- {{ itemd }} --><a-uploadv-if="k == 0"name="avatar"list-type="picture-card"class="avatar-uploader":show-upload-list="false":before-upload="beforeUploads":onRemove="handleRemove"multiplestyle="padding: 0"><div class="ant-upload-text">上传</div></a-upload><a-uploadv-elsename="avatar"list-type="picture-card":show-upload-list="false":before-upload="beforeUploads":onRemove="handleRemove"id="uploadi"><div v-if="itemd != ''" style="width: 100%; height: 100%; margin: 0 auto"><imgv-if="itemd != ''":src="itemd"alt="avatar"style="width: 100%; height: 100%"@click="uploadd(k)"/></div><div v-if="itemd == ''"><div class="ant-upload-text" @click="uploadd(k)">上传</div></div></a-upload><divv-if="itemd != ''"style="position: absolute;top: -2px;right: 3px;z-index: 11111;width: 20px;height: 20px;text-align: center;"@click="handleReset(k)"><a-icon type="close" size="20px" /></div></div>
