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= </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> |
