Angular 6中ng2-file-upload中的进度栏 [英] Progress Bar in ng2-file-upload in Angular 6

问题描述

我想为我的文件上传创建进度条.

Id like to create a progress bar to my file upload.

我正在使用的上载是: https://www.npmjs.com/package/ng2-file-upload.

The Upload I'm using is: https://www.npmjs.com/package/ng2-file-upload.

app.component.html

<div class="container-fluid">
    <div class="row">
        <div class="col-md-12">
            <input type="file" name="myFile" ng2FileSelect [uploader]="uploader" />
        </div>
    </div>
    <div class="row">
        <div class="col-md-12">
            <button type="button" class="btn btn-success btn-s" (click)="uploader.uploadAll()" [disabled]="!uploader.getNotUploadedItems().length">
                Upload an Image
            </button>
        </div>
    </div>
</div>

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { FileUploader, FileSelectDirective } from 'ng2-file-upload';

const URL = 'url to API';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
public uploader: FileUploader = new FileUploader({ url: URL, itemAlias: 'myFile' });

  ngOnInit() {
    this.uploader.onAfterAddingFile = (file) => { file.withCredentials = false; };
    this.uploader.onCompleteItem = (item: any, response: any, status: any, headers: any) => {
      console.log('ImageUpload:uploaded:', item, status, response);
      alert('File uploaded successfully');
    };
 }
}

一切正常，但我只想放一个进度条.

Everything is working fine but Id like to put a progress bar, only this.

推荐答案

您可以在此处听进度

this.uploader.onProgressItem = (progress: any) => {
    console.log(progress['progress']);
};
