jQWidgets jqxGrid scrollmode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。 jqxGrid 用於演示以表格形式顯示數據的 jQuery 小部件。此外，它還全麵支持數據連接、分頁、分組、排序、過濾和編輯。

scrollmode屬性用於設置或獲取顯示的jqxGrid的滾動模式。它是字符串類型，默認值為default。

可能的滾動模式如下：

default:這是規定的默認滾動模式。
logical:這是邏輯模式，其中滾動條拇指的運動是通過行而不是像素進行的。
deferred:這是所謂的延遲模式，隻要用戶拉動滾動條，內容就會保持靜止。

用法:

設置滾動模式屬性。

$('#Selector').jqxGrid({ scrollmode: 'logical'});

返回滾動模式屬性。

var scrollmode = $('#Selector').jqxGrid('scrollmode');
