这种弹出确认删除的对话框怎么做啊？
表格每行的第一列有一个复选框： <input type= 'checkbox ' name=cb>
表格的上面有一个删除按钮： <input type = "button " onclick = "delete() " value= "删除 ">
单击这个删除按钮会激发一个JS事件，来取到该行的ID：
<script language = "javascript ">
function delete()
{
for(i=0;i <document.f1.cb7.length;i++)
{
if(document.f1.cb7[i].checked == true)
{
var index = document.f1.cb7[i].parentElement.parentElement.parentElement.rows(i).cells(1).innerText;
}
}
} </script>

现在ID可以取到，我想在取到该行的ID后，弹出一个确认删除的对话框，如果选是，执行删除数据库的PHP或ASP代码，请问怎么实现啊？

[解决办法]
c#的if(MessageBox.show() == DialogResult.Yes){}就可以解决
[解决办法]
if(confirm( "确认要删除吗？ ")){
//执行删除
}
[解决办法]
function delete()
{
for(i=0;i <document.f1.cb7.length;i++)
{
if(document.f1.cb7[i].checked == true)
{
var index = document.f1.cb7[i].parentElement.parentElement.parentElement.rows(i).cells(1).innerText;
if(window.confirm( "are you sure to delete? "){
doDelete();
}
}
}

[解决办法]
if(confirm( "删除? ")){ //提交页面,或者链接到其他页.}
[解决办法]
private void del_Click(object sender, System.EventArgs e)
{
int index;
index=Session[ "module_authority "].ToString().IndexOf( "80 ");
if(index> 0)
{
string ID= " ",Selected_Date= " ";
foreach(RepeaterItem item in this.Repeater.Items)
{
CheckBox ck=(CheckBox)item.FindControl( "checkbox_del ");
if(ck.Checked)
{
HtmlInputHidden inputhidden = (HtmlInputHidden)item.FindControl( "SelectedID ");

ID +=inputhidden.Value.Trim()+ ", ";
HtmlInputHidden inputhidden2 = (HtmlInputHidden)item.FindControl( "Selected_Date ");
Selected_Date +=inputhidden2.Value.Trim()+ ", ";
}
}
if(ID.Length == 0)
this.Page.RegisterStartupScript( " ", " <script> alert( '没有选定删除项 ');window.location.href=window.location.href; </script> ");
else
{
ID = ID.Remove(ID.Length - 1,1);
Selected_Date = Selected_Date.Remove(Selected_Date.Length-1,1);
string sql_del = "delete from Files where ID in( "+ID+ ") ";
string [] Arr_Id = ID.Split( ', ');
for(int i=0;i <Arr_Id.Length;i++)
{
string strsql= "select FileName from Files where id = "+Arr_Id[i];
Con.Open();
SqlCommand cmd =new SqlCommand(strsql,Con);
SqlDataReader dr1 =cmd.ExecuteReader();
if(dr1.HasRows)
while(dr1.Read())
{
string File_Path = Server.MapPath( "../../Files/WeeklyReport/ "+dr1[ "FileName "].ToString().Trim());
if(File.Exists(File_Path))
File.Delete(File_Path);
}
Con.Close();
}

Conn.ExecuteNonQuery_Sql_alert_refurbish_self(this,sql_del, "删除成功!!! ");
}
}
else
{
this.Response.Write( " <script> alert( '您无权进行此操作,请与系统管理员联系!!! '); </script> ");
}
}

在page_load事件中加入
del.Attributes.Add( "onClick ", "return confirm( '确定删除记录吗？ '); ");
[解决办法]
clientclick= "javascript:return confirm( '您确定要删除吗？ '); "
[解决办法]
if(window.confirm( "您真的要删除吗? "){
调用删除方法
}
