Angularjs ng focus directive-IGI

The ng-focus directive in AngularJS is used to bind a function to the focus event of an HTML element. This event is fired whenever the element receives focus, either through mouse click or keyboard navigation.

Here is an example of using ng-focus with an input element:

<input type="text" ng-model="text" ng-focus="onFocus()">

In this example, the ng-focus directive is bound to a function called onFocus, which is executed whenever the input element receives focus.

Here is an example of the onFocus function:

$scope.onFocus = function() {
  console.log('Input field is in focus');
};

In this example, the onFocus function logs a message to the console whenever the input field receives focus.

You can also use the $event object to access information about the focus event, such as the target element. Here is an example:

<input type="text" ng-model="text" ng-focus="onFocus($event)">

In this example, the onFocus function takes the $event object as an argument, which can be used to manipulate the target element or its attributes. For example, you could change the background color of the input field when it receives focus:

$scope.onFocus = function(event) {
  event.target.style.backgroundColor = 'yellow';
};

In this example, the onFocus function sets the backgroundColor style property of the target element to yellow, giving it a yellow background color when it receives focus.
