28 Sep 20233 minutes to read

You can upload a file programmatically using upload method.
The selected files data, get from getFilesData public method in uploader.

The upload method behaves differently based on its arguments.

• If this method receives any files as arguments, those files only start to upload.
• If it has no argument then all the selected files are will start to upload.

app.component.ts

import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { UploaderComponent } from '@syncfusion/ej2-angular-inputs';
@Component({
    selector: 'app-root',
    templateUrl: './default.html',
    styleUrls: ['./index.css']
})

export class AppComponent {
    @ViewChild('defaultupload')
    public uploadObj?: UploaderComponent;
    public autoUpload: boolean = false;
    public path: Object = {
        saveUrl: 'https://services.syncfusion.com/angular/production/api/FileUploader/Save',
        removeUrl: 'https://services.syncfusion.com/angular/production/api/FileUploader/Remove'
    };
    ngAfterViewInit(): void {
        (document.getElementById('first') as HTMLElement).onclick = (args) => {
            (this.uploadObj as UploaderComponent).upload((this.uploadObj as UploaderComponent).getFilesData()[0]);
        };
        (document.getElementById('full') as HTMLElement).onclick = (args) => {
            this.uploadObj?.upload((this.uploadObj as UploaderComponent).getFilesData());
        };
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { UploaderModule } from '@syncfusion/ej2-angular-inputs';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, UploaderModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule {
}

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
