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 jqxGrid is used to illustrate a jQuery widget that shows data in tabular form. Moreover, it renders full support for connecting with data, as well as paging, grouping, sorting, filtering, and editing.
The updaterow() method is used to update a row or numerous rows. It does not return anything.

- rowIds: It is the stated rowIds that can be returned from getrowid() method. It can be of String type or Number type or an Array type.
