input支持拖拽上传但要设置opcity为0,不能设置diaplay:none或者visiables

  如果不使用拖拽上传的话，只点击上传可使用如下

          <divclass="clickBtn"@click="clickBtn">上传内容</div><inputtype="file"id="fileInput"@change="handleFileChange"style="display: none"/>clickBtn(){console.log("clickFackBtn");document.getElementById('fileInput').click()},handleFileChange(event) {const file = event.target.files[0];console.log(file);},

input同时也支持多选文件上传<input mutilple/>
