这是我的代码,当使用“清空”按钮去调用ClearSelectionStatus方法没有问题,想要的功能也可以实现,可我后台调用该方法提示此对象不包含此属性或此方法(方法为ClearSelection),spread.ClearSelection();js错误,通话清空按钮去调用就没有问题。
并且通过var spread = document.getElementById('<%=FpSpread1.ClientID %>');获取到的spread对象不是null,是pread对象。
我后台是这样调用的ScriptManager.RegisterStartupScript(this, this.GetType(), "ClearSelectionStatus", "ClearSelectionStatus();", true);
