如何从所选选项中获取值

asp-classic javascript

Jenny Tran · 技术社区 · 6 年前

我有一个users表,它有用户id、firstname、lastname和role。我喜欢创建一个经典的asp页面,在选择选项时显示值。每当我从下拉框中选择用户名时,它就会在下面显示其值。我试过了,但是当我在下拉列表中选择一个用户名时,它没有做任何事情。

Here is my code:
User_id   Firstname   Lastname   Role

1         Jenny       Rogers     A

2         Jenny2      Rogers2    A
3         Jenny3      Rogers3    C

ASP代码:

<form action="" method="post" id="newMenu" name="frmReport" onSubmit="return validateForm(this)">
  <table>
    <thead>
      <tr>
        <td>
          <strong>New User: </strong>
          <select name="UserID">
            <option value="">All Users</option>
            <% sSQL = "SELECT DISTINCT User_id, Lastname, Firstname FROM User "
                    objRS.Open sSQL, objConn
                    Do Until objRS.EOF
                        Response.Write("<option value='" & objRS("User_id") & "'>" & objRS("Lastname") & ", " & objRS("Firstname") & "</option>")
                    objRS.MoveNext
                    Loop
                    objRS.Close
                %>
          </select>
          <% 
            If Len("UserID") > 0 Then
                                    sSQL = "SELECT User_id, Role FROM Users WHERE User_id = '" & request.Form("UserID") & "' ; "
                                    objRS.Open sSQL, objConn
                    Do Until objRS.EOF
                %>
            <input type="text" name="Role" value="<%= objRS(" Role ") %>">
            <%  objRS.MoveNext
                    Loop
                    objRS.Close
    End If
                %>
              <input type="hidden" name="FormSource" value="SubmitForm">
              <input type="submit" value="Submit Form">
              </th>
      </tr>
  </table>
</form>
