In AngularJS, you can disable click events on an element by creating a custom directive that stops the event propagation. Here’s an example of how to create a directive called disable-click:

Create a new AngularJS module and directive:

JS Code

angular.module('app', [])
  .directive('disableClick', function() {
    return {
      restrict: 'A',
      link: function(scope, element, attrs) {
        element.bind('click', function(event) {
          event.preventDefault();
          event.stopPropagation();
        });
      }
    };
  });

Use the disable-click directive in your HTML:

HTML Code

<!DOCTYPE html>
<html ng-app="app">
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
    <script src="app.js"></script>
  </head>
  <body>
    <button disable-click>Disabled Button</button>
  </body>
</html>

In this example, the disable-click directive is added to a button element. When you click the button, the click event is prevented and does not propagate, effectively disabling the button’s click event. You can apply the disable-click directive to any element where you want to disable the click event.

Please note that using this method will only disable the click event on the element itself, not its children. If you want to disable click events on an element and all its children, you can modify the directive’s link function to disable click events on the element and its child elements:

JS Code

link: function(scope, element, attrs) {
  element.on('click', function(event) {
    event.preventDefault();
    event.stopPropagation();
  });

  angular.forEach(element.find('*'), function(child) {
    angular.element(child).on('click', function(event) {
      event.preventDefault();
      event.stopPropagation();
    });
  });
}

Here’s a complete example of disabling click events in AngularJS using a custom directive:

index.html – Main HTML file:

<!DOCTYPE html>
<html ng-app="app">
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
    <script src="app.js"></script>
  </head>
  <body>
    <button disable-click>Disabled Button</button>
    <div disable-click>
      <button>Disabled Button Inside Div</button>
    </div>
    <button>Enabled Button</button>
  </body>
</html>

app.js – Main JavaScript file:

angular.module('app', [])
  .directive('disableClick', function() {
    return {
      restrict: 'A',
      link: function(scope, element, attrs) {
        element.on('click', function(event) {
          event.preventDefault();
          event.stopPropagation();
        });

        angular.forEach(element.find('*'), function(child) {
          angular.element(child).on('click', function(event) {
            event.preventDefault();
            event.stopPropagation();
          });
        });
      }
    };
  });

In this example, the disable-click directive is applied to a button element and a div element containing another button. The click events for both the button and the button inside the div are disabled. The third button, which doesn’t have the disable-click directive, functions normally.

This solution disables click events for the target element and all its children, effectively disabling any click interactions within the element.
