What is the most effective method to prompt an "input type="file" dialog using Angular and ng2FileUpload?

I'm currently implementing ng2FileUpload for drag-and-drop file uploads, but I would also like to give users the option to click on the drop area to open the file dialog.

Assuming I have the following input:

<input type="file" ng2FileSelect [uploader]="uploader" style="display: none" />

Is there a way to trigger the file dialog from within the Angular 4 typescript code?

Answer №1

This is the method I found to achieve it:

Using a template:

<input type="file" ng2FileSelect [uploader]="uploader" hidden #fileInput />

In the Angular component:

@ViewChild('fileInput') fileInput:ElementRef;

public openFileExplorer():void {
    let event = new MouseEvent('click', {bubbles: false});
    this.fileInput.nativeElement.dispatchEvent(event);
}
