以下代码使用 jqxgrid 插件。我将循环值更改为 400，以生成 400 页，每页 10 页。
运行时，我只看到 0-26 个链接（270 页），而不是 0-39 个链接。请问我该如何解决这个问题？
在另一种情况下，在我的应用程序中，我只看到 380 页而不是 900 页的分页链接。如果有人可以修复，以下我将能够在我的应用程序中应用相同的解决方案。非常感谢！
较早的代码已被修改，以使用以下示例：
http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/virtualdata.htm?classic
为什么不显示记录？请解释。需要改变什么。非常感谢。
