jQWidgets jqxTreeMap hoverEnabled屬性用法及代碼示例

jQWidgets 是一個 JavaScript 框架，用於為 PC 和移動設備製作基於 Web 的應用程序。它是一個非常強大、優化、獨立於平台且得到廣泛支持的框架。 jqxTreeMap 用於顯示嵌套矩形的分層數據集。這裏，樹的每個分支都表示為一個矩形，然後用代表子分支的較小矩形進行平鋪。這裏，葉節點的矩形的麵積與數據上的指定維度成比例。

懸停啟用屬性用於設置或獲取當鼠標光標位於指定的jqxTreeMap的某個扇區上時是否會顯示該扇區的輪廓。該屬性接受布爾值。

用法:

用於設置懸停啟用屬性：

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

為了得到懸停啟用屬性：

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