Last Updated : 23 Sep, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. The jqxFormattedInput is a jQuery input widget that is used for taking input of numbers in the binary, octal, decimal or hexadecimal format. The input number can be incremented/decremented through the spin buttons which is optional and the numeral system can be changed through a pop-up menu which is also optional.

The selectFirst() method is used to add caret at the beginning of the number in the input field. It does not accept any parameter and does not return any value.

Syntax:

$('Selector').jqxFormattedInput('selectFirst');
