AngularJS ng-blur Directive
Last Updated :
08 Aug, 2022
The ng-blur Directive in AngularJS is fired when an HTML element loses their focus. It doesn’t override with element’s original onblur event i.e. both the ng-blur expression and original onblur event will execute.
Syntax:
<element ng-blur="expression">
Contents...
</element>
Parameter:
- expression: It 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 hides it when the input focus loses.
