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 scrollOffset() method is used to scroll the specified DataTable to a particular position.
Syntax:
$("#dataTable").jqxDataTable('scrollOffset', top, left);Parameters: This method accepts two parameters that are illustrated below.
- top: This is the specified top position up to which scrolling will be done.
- left: This is the specified left position up to which scrolling will be done.
