    How to create dynamic checkbox by using VBscript?

    Hello, I am a beginner of writing vbscript and I am now facing a question, my coding as follow
    [code=asp]<%
    dim ID(5)
    dim value(5)
    dim count = 5
    dim i = 0
    while i<count
    response.write( "<form>")
    response.write( "<input type = checkbox ID = "+ID(i)+" value = "+value(i)+ ">")
    response.write( </form>
    end while
    %>[/code]The output only displays checkboxs with no value and the checkbox can not be accessed even I check it , is there anything wrong with my coding? And is there any solution (or other method) can satisfy the same situation?

      I stop using response.write when I have a long section of HTML code, especially if there are a lot of quote marks. I would write it more like this:
      [code=asp]<%
      dim ID(5)
      dim value(5)
      dim count = 5
      dim i
      for i = 0 to count %>
      <form>
      <input type="checkbox" ID="<%=ID(i)%> " value="<%=value (i)%>">
      </form>
      <%
      next %>[/code]Let me know if this helps.

              Code:
              <%@ Page Language="VB" AutoEventWireup="True" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server" language=vbscript>


    Sub Test(ByVal sender As Object, ByVal e As EventArgs)
        Dim i
        For i = 0 To 4
            Dim name = "ID" + i.ToString
            If name.Checked Then
                Response.Write(name.Value)
            End If
        Next
    End Sub
</script>

<html >

<head id="Head1" runat="server">
    <title> CheckBoxList Example </title>
   
</head>

<body>
<form runat="server" action="">
<%
           Dim ID() = {"John", "Peter", "Tom", "Herman", "Mary"}
           Dim value() = {1, 2, 3, 4, 5}
           Dim count = 5
           Dim i
           For i = 0 To count - 1%>
   
<!--      ＊ --><input type="checkbox" id= "<%="ID"+i.tostring%>" value="<%=ID(i).toString%>" runat="server"/> <%=ID(i).ToString()%>
      
   
<%
next %>
       <input type ="button" value ="Send" runat ="server" onserverclick="Test" />
</form>
</body>

</html>

                  Well this code doesn't assign a value to the value() array. what values do you want in the value() array?

                      This looks like a combination of ASP and ASP.NET, the two are not compatible. Are you trying to write ASP (.asp file extension with VBScript) or ASP.NET (.aspx file extension with VB)?

                          YUP....I am trying to write asp.net however I am not good at using the interal tools provided, so I try do use vbscript to create the interface. But it seems hard to create the dynamic checkbox.

                              the value is dynamic too, as I would like to extract the data from the XML file, such as the title of books in xml document. for example, if there are 2 titles found , there will be a variable called "count" to hold it then using the array to store the values

                              E.g

                              count = xmlDoc.SelectNo des("/Books/Book/Title").count<-----I forget whether it is correct

                              dim values(count)
                              dim i
                              for i = 0 to count
                              'further coding
                              next

                                  Before we go any further you will need to decide which you are going to use. You can not write ASP.NET with VBScript, you will need to use VB.NET in ASP.NET or VBScript in "classic" ASP. The languages are similar, but not identical. Also, the methods for creating dynamic checkboxes are very different. in ASP.NET you can bind a list of checkboxes to the XML data, but in "classic" ASP you would loop through the XML data and create a new checkbox for each row. Does this make sense?
