vue webkitdirectory屬性上傳文件夾

element 上傳組件不支持文件夾上傳，。。。使用input的webkitdirectory屬性可上傳文件夾

<input ref="file"  class="fileUploaderClass" type='file' name="file" webkitdirectory @change.stop="changesData"/>


changesData () {
console.log(this.$refs.file.files)
 this.fileList = this.$refs.file.files  // 獲取filelist
 },
// 上傳
 uploadFile () {
      let formData = new window.FormData()
      for (let i = 0; i < this.fileList.length; i++) {  // 每個file append到formdata裏
        formData.append('file', this.fileList[i])
      }
      let url = Vue.prototype.API_URL + '/imageCompare'
      axios({
        method: 'post',
        url: url,
        data: formData,
        headers: {'Content-Type': 'multipart/form-data'}
      }).then(function (res) {
      })
    },
