jQWidgets jqxTreeMap destroy Method

Last Updated : 11 Nov, 2021

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 jqxTreeMap is used for showing the hierarchical data set of nested rectangles. Here each and every branch of the tree is represented as a rectangle, which is then tiled with smaller rectangles that represent sub-branches. Here the rectangle of the leaf node has an area proportional to a specified dimension on the data.

The destroy method is used for destroying the specified jqxTreeMap widget. This method removes the jqxTreeMap widget from the web page.

$('#jqxTreeMap').jqxTreeMap('destroy');
