How to get FormControl value in Angular?

Publish date: 2024-07-20

Angular provides a powerful way to handle form controls using the FormControl class. In order to get the value of a FormControl in Angular, you can simply access the value property of the FormControl instance. This allows you to read and manipulate the value of form controls without directly accessing the HTML elements. Here’s how you can get the value of a FormControl in Angular:

“`typescript
// Assuming you have a form control named ‘myControl’
console.log(myControl.value);
“`

By accessing the value property of the FormControl instance, you can easily retrieve the current value of the form control.

To further illustrate this, let’s consider a simple example where we have a form control named ‘username’ and we want to get its value. We can do this as follows:

“`typescript
// Assuming you have a form control named ‘username’
console.log(username.value);
“`

By logging the value of the ‘username’ FormControl, you can see the current value of the form control being displayed in the browser console.
