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 getstate() method is used to return the state of the displayed jqxGrid. It has no parameters. It returns an object. Moreover, this method is able to get various information like sort order, sort column, page number, page size, filter row values as well as applied filters, visibility as well as column widths, cells as well as rows selection, and groups.
The value returned here is a JSON object which has the following fields:
- width: It is the stated Grid’s width.
- height: It is the stated Grid’s height.
- pagenum: It is the stated Grid’s page number.
- pagesize: It is the stated Grid’s page size.
