              :disabled="disableBtn"
            >Upload</button>
          </div>

方法代码

onFileChange(e) {
  this.file = this.$refs.file.files[0];
},
uploadFile() {
  if (this.file == "") {
    this.alertClass = "alert alert-danger";
    this.alertMessage = "Please select a file";
    this.showAlert = true;
  } else {
    this.disableBtn = true;
    this.$parent.showLoading();
    let requestUrl =
      this.baseUrl  + "/media";
    let formData = new FormData();
    formData.append("file", this.file,);
    formData.append("mediatype", this.Mediatype);
    let headers = {
      headers: {
        "Content-Type": "multipart/form-data"
      }
    };

    this.$http
      .post(requestUrl, formData, headers)
      .then(response => {
        this.alertClass = "alert alert-success";
        this.alertMessage = response.data.message;
        this.$refs.file.value = ''
        this.showAlert = true;
        this.$parent.hideLoading();
        this.disableBtn = false;
        this.$parent.getGallery();
      })
      .catch(() => {
        this.disableBtn = false;
        this.$parent.hideLoading();
        this.alertClass = "alert alert-danger";
        this.alertMessage =
          "There is a problem in the request.";
        this.showAlert = true;
      });
  }
