I created a service in my component that I subscribe to, but when I use ngFor, the div doesn't render at all.
Component.TS file
import { Component, OnInit } from '@angular/core'; import {FormBuilder, Validators} from '@angular/forms'; import { PlansService } from 'src/app/services/plans.service'; interface JobType { value: string; viewValue: string; } interface WorkEnv { value: string; viewValue: string; } @Component({ selector: 'app-post-job', templateUrl: './post-job.component.html', styleUrls: ['./post-job.component.css'] }) export class PostJobComponent implements OnInit { jobTypes: JobType[] = [ {value: 'type-0', viewValue: '全职'}, {value: 'type-1', viewValue: '兼职'}, {value: 'type-2', viewValue: '自由职业'}, ]; workEnvs: WorkEnv[] = [ {value: 'type-0', viewValue: '远程'}, {value: 'type-1', viewValue: '混合'}, {value: 'type-2', viewValue: '现场'}, ]; jobForm = this.fb.group({ jobTitle: this.fb.group({ title: ['', [Validators.required, Validators.minLength(2), Validators.pattern('^[_A-z0-9]*((-|\s)*[_A-z0-9])*$')]], jobType: ['', [Validators.required]] }), }) plans: any; constructor(private fb: FormBuilder, private service:PlansService) { } ngOnInit(): void { this.service.getPlans() .subscribe(response => { this.plans = response; console.log(response); }); } // Getter method to access formcontrols get myForm() { return this.jobForm.controls; } // Submit Registration Form // onSubmit() { // this.submitted = true; // if(!this.jobForm.valid) { // alert('Please fill all the required fields to create a super hero!') // } else { // console.log(this.jobForm.value) // } // } }
Component.html file
{{plan.title}}
The data shows up in my console.log but doesn't render at all on the card. Please help, thank you!
I tried adding a dummy array in the ts file and printing it to the console log, but it still doesn't render in the div.
You can load your plan asynchronously.
Create an observable object
public plans$: Observable
Assign your subscription
this.plans$ = this.service.getPlans();
Conditionally Rendering in Your HTML
