Submit form on pressing Enter with AngularJS

Submit form on pressing Enter with AngularJS: A Complete Guide

So, you've got a form in your AngularJS application and you want to make it submit or call a function when the user presses the Enter key, huh? 🤔 Don't worry, my friend! I've got you covered. In this blog post, I will show you some easy solutions to this common problem.

The Problem

Let's take a look at the code you provided:

<form>
    <input type="text" ng-model="name" <!-- Press ENTER and call myFunc --> />
    <br />
    <input type="text" ng-model="email" <!-- Press ENTER and call myFunc --> />
</form>

As you can see, you have two input fields, and you want to call the myFunc function when the user presses Enter in any of these fields.

Solution #1: Using ng-keypress

One way to solve this problem is by using the ng-keypress directive provided by AngularJS. You can add it to your input fields like this:

<input type="text" ng-model="name" ng-keypress="keyPressHandler($event, 'name')" />
<br />
<input type="text" ng-model="email" ng-keypress="keyPressHandler($event, 'email')" />

In your controller, define the keyPressHandler function like this:

$scope.keyPressHandler = function(event, field) {
    if (event.keyCode === 13) { // 13 is the key code for Enter key
        // call your function here
        myFunc();
    }
};

Solution #2: Using ng-submit

Another way to achieve the same result is by using the ng-submit directive. Instead of using the ng-keypress directive, you can wrap your input fields inside a form element and use the ng-submit directive on the form:

<form ng-submit="myFunc()">
    <input type="text" ng-model="name" />
    <br />
    <input type="text" ng-model="email" />
</form>

In this solution, the myFunc function will be called when the form is submitted, either by pressing Enter in one of the input fields or by clicking a submit button.
