$uibModal is a service provided by the UI Bootstrap library for AngularJS (1.x) that helps you create modals (dialogs or pop-ups) in your application. To use $uibModal, follow these steps:

Install and include UI Bootstrap:

First, you need to install the UI Bootstrap library and its dependencies. You can either download it from the official website (https://angular-ui.github.io/bootstrap/) or use a CDN like the following:

HTML code

<!-- AngularJS and UI Bootstrap styles -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-csp.css">

<!-- AngularJS and UI Bootstrap scripts -->
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-tpls.min.js"></script>

Create an AngularJS module and controller:

Create a new AngularJS module and controller. Add the ui.bootstrap dependency to your module:

JS code

angular.module('app', ['ui.bootstrap'])
  .controller('MainController', function($scope, $uibModal) {
    // Your main controller logic here
  });

Create the modal template:

Create an HTML file (e.g., modalTemplate.html) that will be used as the modal’s content:

html code

<div class="modal-header">
  <h3 class="modal-title">Modal Title</h3>
</div>
<div class="modal-body">
  This is the modal content.
</div>
<div class="modal-footer">
  <button class="btn btn-primary" ng-click="$ctrl.ok()">OK</button>
  <button class="btn btn-warning" ng-click="$ctrl.cancel()">Cancel</button>
</div>

Create the modal controller:

Create a new AngularJS controller that will handle the modal’s logic:

JS Code

angular.module('app')
  .controller('ModalController', function($uibModalInstance) {
    var $ctrl = this;

    $ctrl.ok = function() {
      $uibModalInstance.close('ok');
    };

    $ctrl.cancel = function() {
      $uibModalInstance.dismiss('cancel');
    };
  });

Open the modal:

In your main controller, create a function that opens the modal using $uibModal.open():

JS Code

$scope.openModal = function() {
  var modalInstance = $uibModal.open({
    templateUrl: 'modalTemplate.html',
    controller: 'ModalController',
    controllerAs: '$ctrl'
  });

  modalInstance.result.then(
    function(result) {
      console.log('Modal closed with:', result);
    },
    function(reason) {
      console.log('Modal dismissed with:', reason);
    }
  );
};

Add a button to open the modal:

Finally, add a button to your HTML that calls the openModal() function:

html code

<body ng-controller="MainController">
  <button ng-click="openModal()">Open Modal</button>
</body>

Now, when you click the “Open Modal” button, a modal will appear with the content and behavior defined in modalTemplate.html and ModalController. You can further customize the modal’s appearance, size, and other options by modifying the $uibModal.open() configuration.

Complete example

Here it is:

index.html – Main HTML file:

<!DOCTYPE html>
<html ng-app="app">
  <head>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-csp.css">

    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-tpls.min.js"></script>
    <script src="app.js"></script>
  </head>
  <body ng-controller="MainController">
    <button ng-click="openModal()">Open Modal</button>
  </body>
</html>

app.js – Main JavaScript file:

angular.module('app', ['ui.bootstrap'])
  .controller('MainController', function($scope, $uibModal) {
    $scope.openModal = function() {
      var modalInstance = $uibModal.open({
        templateUrl: 'modalTemplate.html',
        controller: 'ModalController',
        controllerAs: '$ctrl'
      });

      modalInstance.result.then(
        function(result) {
          console.log('Modal closed with:', result);
        },
        function(reason) {
          console.log('Modal dismissed with:', reason);
        }
      );
    };
  })
  .controller('ModalController', function($uibModalInstance) {
    var $ctrl = this;

    $ctrl.ok = function() {
      $uibModalInstance.close('ok');
    };

    $ctrl.cancel = function() {
      $uibModalInstance.dismiss('cancel');
    };
  });

modalTemplate.html – Modal template:

<div class="modal-header">
  <h3 class="modal-title">Modal Title</h3>
</div>
<div class="modal-body">
  This is the modal content.
</div>
<div class="modal-footer">
  <button class="btn btn-primary" ng-click="$ctrl.ok()">OK</button>
  <button class="btn btn-warning" ng-click="$ctrl.cancel()">Cancel</button>
</div>

This example demonstrates how to create and use a modal using $uibModal in AngularJS with the UI Bootstrap library. When you click the “Open Modal” button, a modal with the content from modalTemplate.html will appear, and you can interact with it using the behavior defined in the ModalController.
