有没有办法测试jqGrid是否有数据？ [英] Is there a way to test if jqGrid has data or not?

问题描述

我正在尝试在jqgrid上启用和禁用自定义按钮，但只有在网格为空时才启用该按钮，然后在没有时禁用。

I'm trying to enable and disable custom buttons on a jqgrid, but would enable that button only if the grid is empty and then disable when its not.

有没有办法测试网格是否有数据？

Is there a way to test of the grid has data or not?

谢谢。

推荐答案

您可以测试以查看网格中有多少条记录。如果没有行则网格为空：

You can test to see how many records are in the grid. If there are no rows then the grid is empty:

jQuery('#grid').jqGrid('getGridParam', 'reccount');

请参阅 reccount ：

Readonly属性。确定网格中的确切行数。

Readonly property. Determines the exactly number of rows in the grid.

此外，由于默认值为 0 您需要确保在加载数据后调用此函数，例如在 loadComplete 事件中。

Also, since the default value is 0 you need to make sure you call this function after data has loaded, such as in the loadComplete event.
