Angularjs Call The Ng Submit Event Outside The Form

You want to take your Angular skills to the next level? Well, let's dive into a nifty trick in Angular that will be a game-changer for your app development: calling the NgSubmit event outside the form element. While Angular is known for its powerful features, it's always exciting to discover new ways to leverage its capabilities.

So, you might be wondering, why would you want to trigger the NgSubmit event from outside the form? Imagine scenarios where you need to validate user inputs, handle form submissions, or even trigger form submissions programmatically. This technique can come in handy when you want to execute form-related functionality without being bound by the form element itself.

To achieve this, we can leverage Angular's ViewChild decorator, ElementRef, and NgForm to access the form's properties and methods. By doing so, we open up a world of possibilities in terms of form manipulation and interaction.

First things first, you'll need to import the necessary modules into your Angular component. Make sure to include the ViewChild and NgForm modules to enable access to the form element and its functionalities.

Next, within your component class, use the ViewChild decorator to access the form element in your template. By doing this, you establish a direct link between your component class and the form element, allowing you to interact with it programmatically.

Typescript

import { ViewChild, ElementRef } from '@angular/core';
import { NgForm } from '@angular/forms';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent {
  @ViewChild('yourForm') yourForm: NgForm;

  // Your component logic here
}

In your template file (HTML), make sure to assign a template reference variable to your form element as shown below. This referencing will be used to access the form in your component class.

Html

<!-- Your form fields here -->

Now that you have established the link between your component class and the form element, you can now programmatically trigger the NgSubmit event using the NgForm reference. Below is an example function that demonstrates how you can call the NgSubmit event outside the form element.

Typescript

import { NgForm } from '@angular/forms';

@Component({
  // Component metadata here
})
export class YourComponent {
  @ViewChild('yourForm') yourForm: NgForm;

  triggerFormSubmit() {
    if (this.yourForm.valid) {
      // Perform form submission logic here
      this.onSubmit();
    }
  }

  onSubmit() {
    // Handle form submission logic
  }
}

By utilizing ViewChild and NgForm, you can easily extend the functionality of your Angular forms and enhance user interactions. So, the next time you find yourself needing to trigger the NgSubmit event outside the form element, remember this handy technique to elevate your Angular development skills!
