I've got my code to post a javascript array in a form:
<form id="my_form" action="file:///C:/Users/John/Desktop/jquery/savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input开发者_如何学运维 type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
</form>
<script type="text/javascript">
function prepare();
{
document.getElementById('seatsArray').value = seatsArray.join();
return true;
}
</script>
Can anyone help me out with the savetext.aspx action file that I need, as my knowledge of ASP.NET is minimal (I'm used to PHP, but this one needs to be ASP.NET).
I guess I can have a crack at getting somewhere near:
<%@ Page Language="C#" %>
<script runat="server">
using System;
using System.IO;
class Test
{
public static void Main()
{
string path = "file:///C:/Users/John/Desktop/jquery/txtfiles/" + request.form("file_name");
if (!File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine(request.form("seatsArray"));
sw.WriteLine("");
}
}
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
}
}
</script>
Am I on the right track?
Many Thanks!
I think you should just use the form as intended, and just add the array data to a hidden element..
<form id="my_form" action="http://my_site/savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
</form>
<script type="text/javascript">
function prepare();
{
document.getElementById('seatsArray').value = seatsArray.join();
return true;
}
</script>
and on the server side use request.form("file_name")
and request.form("seatsArray")
you need use the Stream Class. This is a short code for write / create text files in ASP.NET using VB.NET.
Dim strStreamW As Stream
Dim strStreamWriter As StreamWriter
Try
Dim ds As New DataSet
Dim FilePath As String = "C:\nombreArchivo.txt"
'Open the file, if not exists create it
strStreamW = File.OpenWrite(FilePath)
strStreamWriter = New StreamWriter(strStreamW, _
System.Text.Encoding.UTF8)
'Using a conection with the db
ds = Negocios.TraerDatosArchivo()
Dim dr As DataRow
Dim Nombre as String = ""
Dim Apellido as String = ""
Dim Email as String = ""
For Each dr In ds.Tables(0).Rows
'Get the recordset
Nombre = CStr(dr("Nombre"))
Apellido = CStr(dr("Apellido"))
Email = CStr(dr("Email"))
'Write the line in the file or "stream"
strStreamWriter.WriteLine(Nombre & " " & Apellido & " - " & Email)
Next
strStreamWriter.Close()
Catch ex As Exception
strStreamWriter.Close()
MsgBox(ex.Message)
End Try
