AngularJS – ng-blur Directive
The ng-blur Directive in AngularJS is fired when an element loses focus from that element. The blur event is executed synchronously along with the DOM manipulations (like removing from the focus point).
AngularJS also executes the expression using scope.$evalAsync if the event is fired during an $apply to ensure the consistent application state.
Syntax
<element ng-blur="expression">..Content..</element>
Example 1 − ng-blur Directive
Create a file "ngBlur.html" in your Angular project directory and copy-paste the following code snippet.
<!DOCTYPE html>
<html>
<head>
<title>ngBlur Directive</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
</head>
<body style="text-align: center;">
<h1 style="color: green;">
