Question

该变量应该在单击提交按钮时插入，但不起作用。我认为这可能是我如何调用ajax代码的问题。请帮帮我

<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.3.0-beta.1/jquery.mobile-1.3.0-beta.1.min.js"></script>

        <div id="additem" data-role="page" data-theme="b">
              <div data-role="header">
                <h1>Add Item</h1>
              </div>
          <div data-role="content">
            <form name="form1" method="post" action="">
              <table width="195" border="0" cellpadding="3" cellspacing="3">
                <tr>
                  <td><p> <strong>Item Name</strong></td>
                </tr>
                <tr>
                  <td><input name="item_name" type="text" id="item_name" onFocus="if(this.value=='Item Name')this.value=''" onBlur="if(this.value=='')this.value='Item Name'" value="Item Name"></td>
                </tr>
                <tr>
                  <td><p> <strong>Quantity</strong></p></td>
                </tr>
                <tr>
                  <td><input name="quantity" type="text" id="quantity" size="5"></td>
                </tr>
                <tr>
                  <td><strong>Price</strong></td>
                </tr>
                <tr>
                  <td><p>
                      <input name="price" type="text" id="price" size="5">
                  </p></td>
                </tr>
                <tr>
                  <td>&nbsp;
                  <input type="submit" value="Submit"></td>
                </tr>
              </table>
            </form>

          </div>
          <div data-role="footer">
                <h4>Footer</h4>
          </div>
            </div>
       <script>
    $(document).ready(function(){
        $("form").on('submit',function(event){
        event.preventDefault();

            data = $(this).serialize();

            $.ajax({
            type: "POST",
            url: "item_add.asp",
            data: data
            }).done(function( msg ) {
            alert( "Data Saved: " + msg );
            });
        });
    });
    </script>

插入脚本：

<!--#include file="Connections/shop_app.asp" -->

<%
Dim MM_editAction
MM_editAction = CStr(Request.ServerVariables("SCRIPT_NAME"))
If (Request.QueryString <> "") Then
  MM_editAction = MM_editAction & "?" & Server.HTMLEncode(Request.QueryString)
End If

' boolean to abort record edit
Dim MM_abortEdit
MM_abortEdit = false
%>
<%
' IIf implementation
Function MM_IIf(condition, ifTrue, ifFalse)
  If condition = "" Then
    MM_IIf = ifFalse
  Else
    MM_IIf = ifTrue
  End If
End Function
%>
<%
If (CStr(Request("MM_insert")) = "form1") Then
  If (Not MM_abortEdit) Then
    ' execute the insert
    Dim MM_editCmd

    Set MM_editCmd = Server.CreateObject ("ADODB.Command")
    MM_editCmd.ActiveConnection = MM_shop_app_STRING
    MM_editCmd.CommandText = "INSERT INTO Item_Table (Q_Item, Quantity, Selling_Price) VALUES (?, ?, ?)" 
    MM_editCmd.Prepared = true
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param1", 202, 1, 200, Request.Form("item_name")) ' adVarWChar
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param2", 5, 1, -1, MM_IIF(Request.Form("quantity"), Request.Form("quantity"), null)) ' adDouble
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param3", 5, 1, -1, MM_IIF(Request.Form("price"), Request.Form("price"), null)) ' adDouble
    MM_editCmd.Execute
    MM_editCmd.ActiveConnection.Close
  End If
End If
%>

当我点击提交按钮时，会出现错误，说明错误加载页面

使用ajax调用插入脚本无法正常工作
