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.
