In this tutorial, we will learn how to hide a form on submit using AngularJS. The use case for this could be when you have a form that you want to hide after the user has submitted it to prevent multiple submissions or to display a confirmation message instead of the form. We will achieve this by leveraging AngularJS and its powerful two-way data binding capabilities.
Prerequisites:
Before we begin, ensure that you have the following prerequisites in place:
- Basic knowledge of HTML, CSS, and JavaScript.
- Node.js and npm installed on your system.
- An understanding of AngularJS.
Step 1: Setup
First, create a new HTML file and add the necessary scripts for AngularJS. You can either download AngularJS and include it locally or use a CDN link. Here is an example of how you can include AngularJS in your HTML file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Hide Form on Submit with AngularJS</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="myController">Step 2: Create the form
Next, create a simple form in your HTML file. This form will include an input field for the user to enter their name and a submit button. Here is an example of the form:
<form ng-show="showForm" ng-submit="submitForm()">
<label for="name">Name:</label>
<input type="text" id="name" ng-model="name" required>
<button type="submit">Submit</button>
</form>In the form element, we have added the ng-show directive which binds the visibility of the form to the value of the variable showForm in our AngularJS controller. We have also added the ng-submit directive which calls the submitForm() function when the form is submitted.
Step 3: Create the AngularJS controller
Next, create an AngularJS controller in your HTML file. This controller will hold the logic for hiding the form on submit. Here is an example of the controller:
<script>
var app = angular.module('myApp', []);
app.controller('myController', function($scope) {
$scope.showForm = true;
$scope.submitForm = function() {
// Add your form submission logic here
// For now, we will just hide the form
$scope.showForm = false;
}
});
</script>In the controller, we have initialized the showForm variable to true, which means the form will be initially visible. We have also defined the submitForm() function, which sets the value of showForm to false when the form is submitted, hiding the form.
Step 4: Test the functionality
Finally, open your HTML file in a web browser and test the functionality. Enter a name in the input field and click the submit button. You should see that the form gets hidden after submission.
Conclusion:
In this tutorial, we have learned how to hide a form on submit using AngularJS. By leveraging AngularJS directives and two-way data binding, we were able to dynamically change the visibility of the form based on user actions. You can further enhance this functionality by adding validation, confirmation messages, or other custom logic to your form submission process. Experiment with different AngularJS features to create a seamless and interactive user experience.
