jQWidgets jqxDateTimeInput allowNullDate Property

  • Last Updated : 15 Sep, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxDateTimeInput widget is a jQuery datetimeinput that is used for selecting the date or time using a displayed calendar or by using the keyboard.

The allowNullDate property is used to set or return whether the null value is allowed as an input value or not. It accepts Boolean type value and its default value is true.

Syntax:

Set the allowNullDate property.

$('selector').jqxDateTimeInput({ allowNullDate: Boolean });

 



Return the allowNullDate property.

var allowNullDate = $('selector').jqxDateTimeInput('allowNullDate');
