Angularjs ng readonly directive

The ng-readonly directive in AngularJS is used to conditionally set the readonly attribute of an element. Here's an example:

<input type="text" ng-model="myText" ng-readonly="myCondition">

In this example, we're using the ng-readonly directive to conditionally set the readonly attribute of the input field based on the value of myCondition, which is an expression that you define in your controller.

If myCondition is true, the input field will be read-only. If myCondition is false, the input field will be editable.

Here's an example of how you might define myCondition in your controller:

app.controller('MyController', function($scope) {
  $scope.myCondition = true;
});

In this example, we're using the app.controller method to define a new controller called MyController. Within the controller, we define the myCondition variable and set it to true.

When the page loads, the input field will be read-only because myCondition is true. If you change the value of myCondition to false, the input field will become editable.

Note that the ng-readonly directive should only be used to conditionally set the readonly attribute of an element. In most cases, you should use the ng-model directive to bind form inputs to variables, and use JavaScript to set the readonly attribute dynamically if needed. Also, keep in mind that setting an input field to read-only does not prevent the user from submitting data via other means (such as using the browser's developer tools or modifying the HTML source). To prevent unwanted modifications to data, you should also perform server-side validation and sanitization of user
