Page.RegisterStartupScript的使用方法

用于后台输出Javascript执行段

打开一个新窗口：

Page.RegisterStartupScript("starup", "<script language = 'javascript'>window.open('" + url + "','','toolbar=no,resizable=yes,scrollbars=yes')</script>")

警告窗口
/// <summary>
/// 服务器端弹出alert对话框
/// </summary>
/// <param name="str_Message">提示信息,例子："不能为空!"</param>
/// <param name="page">Page类</param>
public void Alert(string str_Message,Page page)
{
page.RegisterStartupScript("","<script>alert('"+str_Message+"');</script>");
}

重载此警告窗口,使某控件获得焦点

/// <summary>
/// 服务器端弹出alert对话框，并使控件获得焦点
/// </summary>
/// <param name="str_Ctl_Name">获得焦点控件Id值,比如：txt_Name</param>
/// <param name="str_Message">提示信息,例子："请输入您姓名!"</param>
/// <param name="page">Page类</param>
public void Alert(string str_Ctl_Name,string str_Message,Page page)
{
page.RegisterStartupScript("","<script>alert('"+str_Message+"');document.forms(0)."+str_Ctl_Name+".focus(); document.forms(0)."+str_Ctl_Name+".select();</script>");
}

确认对话框

/// <summary>
/// 服务器端弹出confirm对话框
/// </summary>
/// <param name="str_Message">提示信息,例子："您是否确认删除!"</param>
/// <param name="btn">隐藏Botton按钮Id值,比如：btn_Flow</param>
/// <param name="page">Page类</param>
public void Confirm(string str_Message,string btn,Page page)
{
page.RegisterStartupScript("","<script> if (confirm('"+str_Message+"')==true){document.forms(0)."+btn+".click();}</script>");
}

重载确认对话框，点击确定触发一个隐藏按钮事件，点击取消触发一个隐藏按钮事件

/// <summary>
/// 服务器端弹出confirm对话框,询问用户准备转向那些操作，包括“确定”和“取消”时的操作
/// </summary>
/// <param name="str_Message">提示信息，比如："成功增加数据,单击""确定""按钮填写流程,单击""取消""修改数据"</param>
/// <param name="btn_Redirect_Flow">"确定"按钮id值</param>
/// <param name="btn_Redirect_Self">"取消"按钮id值</param>
/// <param name="page">Page类</param>
public void Confirm(string str_Message,string btn_Redirect_Flow,string btn_Redirect_Self,Page page)
{
page.RegisterStartupScript("","<script> if (confirm('"+str_Message+"')==true){document.forms(0)."+btn_Redirect_Flow+".click();}else{document.forms(0)."+btn_Redirect_Self+".click();}</script>");
}

获得焦点

/// <summary>
/// 使控件获得焦点
/// </summary>
/// <param name="str_Ctl_Name">获得焦点控件Id值,比如：txt_Name</param>
/// <param name="page">Page类</param>
public void GetFocus(string str_Ctl_Name,Page page)
{
page.RegisterStartupScript("","<script>document.forms(0)."+str_Ctl_Name+".focus(); document.forms(0)."+str_Ctl_Name+".select();</script>");
}

子窗体返回主窗体

///<summary>
///名称：redirect
///功能：子窗体返回主窗体
///参数：url
///返回值：空
///</summary>
public void redirect(string url,Page page)
{
if ( Session["IfDefault"]!=(object)"Default")
{
page.RegisterStartupScript("","<script>window.top.document.location.href='"+url+"';</script>");
}
}
