}
timer_click触发器和更新面板.并且警报消息不会显示在timer_tick事件上
当您使用更新面板时,您不能像上面那样调用javascript.你必须使用ScriptManager.RegisterStartupScript
所以改变你的
Page.ClientScript.RegisterStartupScript(this.GetType(), "myKey", javaScript);
至
ScriptManager.RegisterStartupScript(updatePanelId,updatePanelId.GetType()
, "alert", javaScript, true);
