Struggling with Form Submission in Angular 14: Reactive Forms Not Updating on Value Change
I'm building a feature where I'm trying to figure out I'm confused about I'm working on a personal project and I'm working on a personal project and I'm encountering an issue with reactive forms in Angular 14 where changes to the form fields are not being reflected in the submitted values. I have a form that includes a couple of fields, and I want to update the value of a dropdown based on the selection of a radio button. However, when I submit the form, the values seem stale and do not reflect the latest changes. Here's a small snippet of my code: ```typescript import { Component, OnInit } from '@angular/core'; import { FormBuilder, FormGroup } from '@angular/forms'; @Component({ selector: 'app-my-form', templateUrl: './my-form.component.html', }) export class MyFormComponent implements OnInit { myForm: FormGroup; constructor(private fb: FormBuilder) { this.myForm = this.fb.group({ option: [''], detail: [''], }); } ngOnInit() { this.myForm.get('option').valueChanges.subscribe(value => { if (value === 'specificOption') { this.myForm.get('detail').setValue('Updated Detail'); } }); } onSubmit() { console.log(this.myForm.value); // Expected to have { option: 'specificOption', detail: 'Updated Detail' } } } ``` The HTML for the form looks like this: ```html <form [formGroup]="myForm" (ngSubmit)="onSubmit()"> <label> <input type="radio" formControlName="option" value="specificOption"> Specific Option </label> <label> <input type="radio" formControlName="option" value="otherOption"> Other Option </label> <div> <input type="text" formControlName="detail"> </div> <button type="submit">Submit</button> </form> ``` When I select the 'specificOption' radio button, I can see in the template that the 'detail' field updates immediately. However, upon form submission, the console log only shows the original values of the form, meaning the updates are not being persisted. I tried adding `updateOn: 'blur'` to the form controls but that didn't change anything. Is there something I'm missing here? How can I ensure that the latest values are submitted? I'm developing on Windows 11 with Typescript. Any advice would be much appreciated. What's the best practice here?
