为什么这段js在本地正常，发布都服务器上就出错了呢！求解
代码 如下：
<script language="javascript"> var getFromParent = window.dialogArguments; function CheckSelect() { var aaaa = ""; for (var i = 0; i < window.document.formfoo.elements.length; i++) { var e = this.formfoo.elements[i]; if (e.checked) { if (aaaa == "") { aaaa = e.value; } else { aaaa = aaaa + "," + e.value; } } } return aaaa; } function sendFromChild() { window.returnValue = CheckSelect(); window.close(); } function CCC() { window.returnValue = ""; window.close(); } </script><html><head> <title>选择条件</title> <meta http-equiv="Content-Language" content="zh-cn"> <link href="../Style/Style.css" type="text/css" rel="STYLESHEET"> <meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1"> <meta name="CODE_LANGUAGE" content="C#"> <meta name="vs_defaultClientScript" content="JavaScript"> <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"> <base target="_self" /> <script language="javascript"> var getFromParent = window.dialogArguments; function CheckSelect() { var aaaa = ""; for (var i = 0; i < window.document.formfoo.elements.length; i++) { var e = this.formfoo.elements[i]; if (e.checked) { if (aaaa == "") { aaaa = e.value; } else { aaaa = aaaa + "," + e.value; } } } return aaaa; } function sendFromChild() { window.returnValue = CheckSelect(); window.close(); } function CCC() { window.returnValue = ""; window.close(); } </script></head><body scroll="no"> <form id="formfoo" method="post" runat="server"> <table border="0" width="100%" cellspacing="0" cellpadding="0" height="100%" bordercolorlight="#c0c0c0" bordercolordark="#ffffff"> <tr> <td height="22" background="../images/show_02.gif" align="left" style="font-size: 12px; font-family: 宋体"> 请选择您需要的项，然后点“确定”！ </td> </tr> <tr> <td valign="top" style="text-align: center"> 查询：<asp:TextBox ID="TextBox1" runat="server" Height="20px" Width="100px"></asp:TextBox><asp:ImageButton ID="ImageButton4" runat="server" ImageAlign="AbsMiddle" ImageUrl="../images/Button/BtnSerch.jpg" OnClick="ImageButton4_Click" /><br /> <table border="0" cellspacing="0" cellpadding="0" style="width: 318px; height: 49px"> <tr> <td colspan="2" style="height: 31px; text-align: center;"> <asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" BorderWidth="1px" Width="100%" ShowHeader="False" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" PageSize="10"> <PagerSettings FirstPageText="首页" LastPageText="最后一页" NextPageText="下一页" PreviousPageText="上一页" /> <FooterStyle BackColor="#F2F5FA" /> <Columns> <asp:TemplateField> <ItemTemplate> <input id="Checkbox1" value='<%#DataBinder.Eval(Container.DataItem, "SelectContent")%>' type="checkbox" runat="server" /> </ItemTemplate> <ItemStyle Width="30px" /> </asp:TemplateField> <asp:TemplateField> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "SelectContent")%>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> <RowStyle Height="20px" HorizontalAlign="Center" /> <EmptyDataTemplate> 你所查看的选项无可用信息！ </EmptyDataTemplate> <PagerStyle BackColor="White" /> <HeaderStyle Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Size="12px" Font-Strikeout="False" Font-Underline="False" ForeColor="HotTrack" Height="30px" /> </asp:GridView> </td> </tr> <tr> <td colspan="2" style="height: 31px; text-align: center;"> <asp:TextBox ID="TextBox4" runat="server" Enabled="False" Width="0px" Height="0px"></asp:TextBox> <input type="button" value="确定" onclick="sendFromChild();" style="width: 70px" class="BottonCss"> </td> </tr> </table> </td> </tr> <tr> <td height="22" background="../images/show_02.gif"> </td> </tr> </table> </form></body></html>求解 ，谢谢
<form id="formfoo" name="formfoo" method="post" runat="server">少个name 属性 name="formfoo"
[解决办法]
按照标准写法试试。
function CheckSelect() { var tmp = [], form = document.getElementById("formfoo"), items = form.getElementsByTagName("input"); for(var i = 0,len = items.length;i < len;i++){ var input = items[i]; if(input.checked) tmp.push(input.value); } return tmp.join(",");}
