【转载】asp.net 后台弹出提示框

感觉这种最好用：

public void showMessage(string str_Message)
        {
            ClientScript.RegisterStartupScript(this.GetType(), "结果", "alert('" + str_Message + "');", true);
            // Define the name and type of the client scripts on the page.


            String csname1 = "PopupScript";
            String csname2 = "ButtonClickScript";
            Type cstype = this.GetType();
            ClientScriptManager cs = Page.ClientScript;
            if (!cs.IsStartupScriptRegistered(cstype, csname1))
            {
                String cstext1 = "alert('Hello World');";
                cs.RegisterStartupScript(cstype, csname1, cstext1, true);
            }
            if (!cs.IsClientScriptBlockRegistered(cstype, csname2))
            {
                System.Text.StringBuilder cstext2 = new System.Text.StringBuilder();
                cstext2.Append("<script type="text/javascript"> function DoClick() {");
                cstext2.Append("Form1.Message.value='Text from client script.'} </");
                cstext2.Append("script>");
                cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false);
            }


            //ClientScript.RegisterClientScriptBlock(this.GetType(), "tishi", "<script type='text/javascript'>alert('你所查询的数据不存在！');</script>");

            //Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "tishi","<script type='text/javascript'>alert('你所查询的数据不存在！');</script>");
            //ClientScriptManager scriptManager =((System.Web.UI.Page)System.Web.HttpContext.Current.Handler).ClientScript;
            //scriptManager.RegisterStartupScript(typeof(string), "", "alert('str_Message');", true);
            //scriptManager.RegisterStartupScript(typeof(string), "", "alert('str_Message');self.location='redirect'", true);
        }

1.后台弹出提示信息方法

Response.Write("<scripttype="text/javascript">alert('你所查询的数据不存在！');</script>");

//弹出提示信息，但页面空白 Page.RegisterClientScriptBlock("tishi", "<scripttype="text/javascript">alert('你所查询的数据不存在');</script>");

//弹出提示信息，但页面空白 Page.RegisterStartupScript("tishi", "<scripttype="text/javascript">alert('你所查询的数据不存在');</script>");//已过期，

//弹出提示信息，页面不空白 ClientScript.RegisterClientScriptBlock(this.GetType(), "tishi","<script type="text/javascript">alert('你所查询的数据不存在！');</script>");

//弹出提示信息，但页面空白 ClientScript.RegisterStartupScript(this.GetType(), "tishi","<script type="text/javascript">alert('你所查询的数据不存在！');

</script>");

//弹出提示信息，页面不空白
//在vs2005中 需要引入System.Web.Extensions.dll ScriptManager.RegisterClientScriptBlock(this.btnTiShi, typeof(Button),"tishi", "alert('你所查询的数据不存在！');", true);

//弹出提示信息，但页面空白 ScriptManager.RegisterClientScriptBlock(this, this.GetType(),"tishi", "alert('你所查询的数据不存在！');", true);

//弹出提示信息，但页面空白,this表示page ScriptManager.RegisterStartupScript(this.btnTiShi, typeof(Button),"tishi", "alert('你所查询的数据不存在！');", true);

//弹出提示信息，页面不空白 ScriptManager.RegisterStartupScript(Page,typeof(Page), "tishi","alert('你所查询的数据不存在！');", true);

//弹出提示信息，页面不空白 ScriptManager.RegisterStartupScript(this, typeof(_Default), "tishi",script, true);

//弹出提示信息，页面不空白,this表示page

//后台获得confirm返回值，并有选择的执行语句块 C#端： protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { this.btnTiShi.Attributes.Add("onclick","tishi()"); } }

protected voidbtnTiShi_Click(object sender, EventArgs e) { if (this.hidevalue.Value == "1") { Response.Write("success"); } else { Response.Write("failue"); } }

JS端： <script type="text/javascript"> function tishi() { if(confirm('你确定要删除吗？')) { document.getElementByIdx_x('hidevalue').value='1'; //window.location.href=window.location.href; } else { document.getElementByIdx_x('hidevalue').value='0'; } } </script>
