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 jqxDataTable is used for reading and displaying the data from the HTML Table. This is also used to display data from various data sources like XML, JSON, Array, CSV, or TSV.
The sortBy() method is used to sort a specified column if sortable is set to true.
Syntax:
$("#dataTable").jqxDataTable('sortBy', 'dataField', 'sortOrder');Parameters: This method accepts two parameters which are illustrated below:
- dataField: This is the specified column name according to which sorting will be executed.
- sortOrder: This is the sorting order string. Its value is ‘asc’ (ascending), ‘desc’ (descending) or null.
