Inquiry regarding the ng-disabled directive in AngularJS

<div ng-app="myApp" ng-controller="myCtrl">
<button type="submit" class="btn btn-primary pull-left" ng- 
disabled="captchaError">Submit</button>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function ($scope) {
    $scope.captchaError = true;                         
});
</script>

Presenting my code snippet. I have configured captcha error to true result in disabling the button. My concern is when this page is launched and a user inspects that button, removing the disabled="disabled" attribute from the element will enable the button. Is there any method to anticipate this scenario and ensure that the button does not activate upon removal of disabled="disabled"

If you want to prevent users from accessing the F12 key on their keyboard, you have a few options. One common method is to disable the F12 key on the screen or disable the prevent option.

How can I block F12 keyboard key in jquery for all my pages and elements?

Keep in mind: Even if you block the F12 key, users may still find ways to edit elements using shortcuts like Control+Shift+i to open the developer panel or accessing Developer Tools through Chrome's menu.

  • If the user press Control+shift+i -> It opens developer panel .

  • Top right square in chrome -> More tools -> Developer tools ,it opens


Instead of simply disabling elements, consider using ng-if to control the creation of DOM elements based on specific conditions.

The ng-if directive removes the HTML element if the expression evaluates to false

<button type="submit" class="btn btn-primary pull-left" ng- 
if="!captchaError">Submit</button>
