使用 GridWeb 的 OnAjaxCallFinishedClientFunction

可能的使用场景

OnAjaxCallFinishedClientFunction 是一个客户端函数,当用户将某些数据复制到 GridWeb 工作表时调用。当大量单元格更新并且您希望在客户端(即在 FireFox、Google Chrome 等网络浏览器中)跟踪这些更新的单元格时,此功能非常有用。

使用 GridWeb 的 OnAjaxCallFinishedClientFunction

以下示例代码说明了如何使用 OnAjaxCallFinishedClientFunction 客户端函数。屏幕截图显示了执行代码时 Google Chrome 和 FireFox 中的控制台输出。执行代码后,请复制/粘贴 GridWeb 工作表内多个单元格的一些数据,然后检查 Web 浏览器控制台,如屏幕截图所示。
