angular6

问题 This error appears when the code is built and deployed to Azure. When the code is run locally using VSCode this doesn't appear in the console. Any help regarding this matter is appreciated.

问题 I'm new to angular 6 so please. I have my component.ts where i'm having my response. Now I want to bind data based on filter value in my HTML page. That is when the user clicks on the Owner Name . Now I want to display the owner name on the top right corner of my HTML page. How can I achieve that? Here is how my HTML page looks like. My component.ts page looks like this: import { CampaignService } from './../../../services/campaign.service'; import { Component, OnInit, Input } from '@angular

问题 In the loop body in the code below: <ul> <li *ngFor="let article of articles; index as i"> <a>{{ articles[i].title }} -- {{i}}</a> <p>{{ articles[i].body }}</p> <!-- i++ --> <p>{{ i }}</p> </li> </ul> Is there anyway to store the value of i++ at that position, then print out new value of i ? Then, i 's value is updated with the new value and used in the next loop. I would like to loop 2 elements at a time, not just one. It's just like what we can do in Java as below: for (int i = 0; i < 10; i

问题 I have this code: this.userService.register(value).pipe( finalize(() => this.isRequesting = false) ).subscribe( () => this.router.navigate(['/login'], { queryParams: { brandNew: true, email: value.email } }), (error: any) => this.errors = error ); It doesn't work until I put a semicolon before this.router : () => ; this.router.navigate(['/login'], { queryParams: { brandNew: true, email: value.email } }), It is really weird, why should this be happening? It has nothing to do with this.router

问题 So, I have the following service in an Angular 6 codebase: export class GenericService<T> { public endpoint: string; constructor(private http: HttpClient) {} public create(entity: T): Observable<T> { return this.http.post<T>(`${environment.apiUrl}/api/${this.endpoint}`, entity); } } As you can see, the observable create(entity: T) method returns the entity it creates. In the component, it is handled thus: @Component({ selector: 'app-brand-dialog', templateUrl: './brand-dialog.component.html',

问题 I am trying to make a POST request from an Angular 6 app to a Django backend. Even though I include the csrf token in the headers, Django is logging a 403 Forbidden error as "CSRF token missing or incorrect". My code is as follows (with extraneous headers in my attempts to satisfy Django): Angular Component: import { Injectable } from '@angular/core'; import { HttpClient, HttpHeaders } from '@angular/common/http'; import { SharedService } from '../../shared.service'; import { CookieService }

问题 As you can see by the subject, I am receiving this error because one of the columns in the database is a string of JSON and I thought I could get around this by having an ngFor loop within an ngFor loop. The following is the html: <tbody> <tr *ngFor="let item of mf.data"> <td>{{ item.id }}</td> <td>{{ item.user_id }}</td> <td class="text-right">{{ item.orders_id }}</td> <td> <ul *ngFor="let x of item.product"> <li>{{ x.name }}</li> <li>{{ x.price }}</li> <li>{{ x.category }}</li> <li>{{ x.ts
