A Better Way to reset the module

You have seen that by using 'resetUpload' property, you can reset the module easily, however if you need to reset more than one time, there's a better way of doing that( bcoz in 'resetUpload' property, you have to make it as false in order to use it again):-

Example-3

<angular-file-uploader #fileUpload1
      [config]="afuConfig"
      [resetUpload]=resetVar
      (ApiResponse)="DocUpload($event)">
</angular-file-uploader>

• Assign one local reference variable (here 'fileUpload1') to the component.
• Now use this local reference variable in your xyz.component.ts file.

      @ViewChild('fileUpload1')
      private fileUpload1:  AngularFileUploaderComponent;

  • Remember to import ViewChild and AngularFileUploaderComponent properly in your component.

      import { ViewChild } from '@angular/core';
      import { AngularFileUploaderComponent } from "angular-file-uploader";

• That's it.....all done, now just use

      this.fileUpload1.resetFileUpload();

  to reset the module hassle-free anytime.

Styling:

Following classes are available for customisation :

Include them in your global css class (src/styles.css)

Use '!important' if something doesn't works

• .afu-select-btn {}
• .afu-reset-btn {}
• .afu-upload-btn {}
• .afu-dragndrop-box {}
• .afu-dragndrop-text {}
• .afu-constraints-info {}
• .afu-valid-file {}
• .afu-invalid-file {}
• .afu-progress-bar {}
• .afu-upload-status {}
• .afu-attach-pin {}

Points to note:

• Files are uploaded in FormData format.

Coming Soon:

• More themes.
