可能的使用场景
OnAjaxCallFinishedClientFunction 是一个客户端函数，当用户将一些数据复制到 GridWeb 工作表时调用它。当大量单元格更新并且您希望在客户端跟踪这些更新的单元格时（即在 FireFox、Google Chrome 等网络浏览器中），此功能很有用。
使用 GridWeb 的 OnAjaxCallFinishedClientFunction
以下示例代码解释了如何使用 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，请在 GridWeb 工作表中复制/粘贴一些跨越多个单元格的数据，然后检查 Web 浏览器控制台，如屏幕截图所示。
