  • vue element-ui 隐藏上传按钮

    1、template:

    <div style="text-align: initial;margin-top: 20px;">
      <el-upload
          :class="{hide:hideUpload}"
          action= ''
          list-type="picture-card"
          :auto-upload="false"
          :show-file-list='true'
          :file-list="certificates"
          :on-preview="showimg"
          :on-change="handlePictureCardPreview"
          :limit="3"
          accept=".jpg,.jpeg,.png,.JPG,.JPEG"
          :on-exceed="handleExceed"
          :on-remove="handleRemove">
          <i class="el-icon-plus" ></i>
        </el-upload>
        <el-dialog :visible.sync="dialogVisible">
        <img width="100%" :src="showimgs" alt="">
      </el-dialog>
     </div>
    

    2、export default:

    certificate: [],
    certificates: [],
    showimgs: '', dialogVisible: false, hideUpload: false, limitCount: 3,

    3、methods:

    //放大显示图片
    showimg(file) {   this.showimgs = file.url   this.dialogVisible = true },
    //限制图片弹窗 handleExceed(files, fileList) {   this.$message.warning(`当前限制选择 3 个文件,本次选择了 ${files.length} 个文件,共选择了 ${files.length + fileList.length} 个文件`); },
    //移除图片 handleRemove(file, fileList) {   var that = this   that.certificate = []   fileList.forEach((item, index) => {     that.certificate.push(item.url);   });
      //当图片大于或等于3张,   this.hideUpload = fileList.length >= this.limitCount; },
    //选择图片 handlePictureCardPreview(file, fileList) {   var that = this   fileList.forEach((item, index) => {     if (item.raw) {       var reader = new FileReader()       reader.readAsDataURL(item.raw)       reader.onload = function () {         that.certificate.push(reader.result)       }     }   });   console.log(fileList.length);   if(fileList.length == 3) {     this.showBtnImg = false;     this.noneBtnImg = true;   }   this.hideUpload = fileList.length >= this.limitCount; },

    4、style:

    .hide .el-upload--picture-card{
       display: none !important;   /* 上传按钮隐藏 */
    }
    

    需要注意的是,style 必须把 scope 移除掉,隐藏上传按钮才会生效!
