jQWidgets jqxTreeMap selectionEnabled属性用法及代码示例

jQWidgets是一个 JavaScript 框架，用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大、优化、独立于平台且得到广泛支持的框架。这jqxTreeMap用于显示嵌套矩形的分层数据集。这里，树的每个分支都表示为一个矩形，然后用代表子分支的较小矩形进行平铺。这里，叶节点的矩形的面积与数据上的指定维度成比例。

选择启用属性用于设置或获取指定的jqxTreeMap的某个扇区被点击时是否显示轮廓。

用法:

用于设置选择启用属性：

$('#jqxTreeMap').jqxTreeMap({ selectionEnabled: true });

为了得到选择启用属性：

var selectionEnabled = 
    $('#jqxTreeMap').jqxTreeMap('selectionEnabled');
