AngularJS | ng-blur Directive

The ng-blur Directive in AngularJS is fired when an HTML element loses their focus. It doesn’t override with element original onblur event i.e. both the ng-blur expression and original onblur event will execute.

Syntax:

<element ng-blur="expression"> Contents... </element>

Where expression refers to the variable or the expression to be evaluated.

Note: The ng-blur directive is supported by <input>, <a>, <select> and <textarea>.

Example 1: This example displays the text message “Enter your text here” when the input is focused and hide it when the input focus loses.

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>ng-blur 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">GeeksforGeeks</h1> 
    <div ng-app="app"> 
        <div ng-controller="gfg"> 
            <h3>ng-blur Directive</h3> 
            <h5 ng-show="msg">Enter your text here</h5> 
            <input type="text" ng-focus="msg=true" ng-blur="msg=false" /> 
        </div> 
    </div> 
    <script> 
        var app = angular.module("app", []); 
        app.controller('gfg', ['$scope', function ($fun, $timeout) { 
                $fun.msg = false; 
        }]); 
    </script> 
</body> 
  
</html> 

Output:
When input is focused:
ng-blur
When input is not focused:
ng-blur

Example 2: This example counts the number of times focus removed from the textarea.

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>ng-blur Directive</title> 
  
    <script src= 
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> 
    </script> 
</head> 
  
<body ng-app="" style="text-align:center"> 
      
    <h2 style="color:green">ng-blur Directive</h2> 
    <textarea ng-blur="count = count + 1" ng-init="count=0"> 
    </textarea> 
      
    <h3>Number of times focus losed: {{count}}</h3> 
</body> 
  
</html> 

Output:
ng-blur
