如何动态构建FORM表单提交到另一个页面

另外还有一个问题,就是同步登录,网上说只要新建一个虚拟目录,配置相同的<machineKey validationKey="BA49E68353EDEC9AE746E4BC3829801B8CDBFE936A6471F232992728B15535F5610579C6BA854916535816BDF4957B6EC65F9CF9B707A4007DA0EA1F1B710DAD"
decryptionKey="2657F2850213E0C0CEDA92C954700C4C266A756EC426A359" validation="SHA1" />
和 <forms name=".ASPXAUTH" loginUrl="/web/UserLogin/Index.aspx"/>
就可以了,为什么我不行啊

你可以考虑用xmlhttpRequest post 一个form 过去我下班了~ 明天来了再帮你看吧

<form id='tempForm' name='tempForm' action='http://192.168.22.251:907/Mc/default.aspx?act=login' method='post' target='_blank' >
<input type='hidden' name='UserName' value='admin'>
<input type='hidden' name='Password' value='1234567'>
<input type='hidden' name='Chknum' value=''> </form>
<script>document.getElementById('tempForm').submit();
alert("aaa");
</script>
这是我HTML代码,每次一打开页面不执行,一定要刷新一次才执行
有没有办法第一次加载时也执行

你把这段代码放page load里就可以了

    protected void Page_Load(object sender, EventArgs e)
    {
         //放在if里是第一次加载执行
         if (!IsPostBack)
         {
            rp.DataSource = getDateTable();
            rp.DataBind();
         }
         else  //else 是回发的时候执行
         {         }
         // 这里是每次都执行
    }

.....这个我知道
不过我在HTML页面里做的试验

protected void Page_Load(object sender, EventArgs e)
    {
         //放在if里是第一次加载执行
         if (!IsPostBack)
         {
           StringBuilder sb = new StringBuilder();
           sb.Append("<form id='tempForm' name='tempForm' action='http://192.168.22.251:907/Mc/default.aspx?act=login'  method='post' target='_blank' >");
           sb.Append("<input type='hidden' name='userName' value='admin'>");
           sb.Append("<input type='hidden' name='userPwd' value='1234567'>");
           sb.Append("<input type='hidden' name='Chknum' value=''></form><script>document.getElementById('tempForm').submit();</script>");           formStr = sb.ToString();         }

    }

不过不可能放在PAGE_LOAD中啊,因为只有用户点击登录之后我才取得到用户名和密码放到表单中啊

...我之前写在button 的click 中就是相当于点了登陆啊

    这个表单我写在最外面
StringBuilder sb = new StringBuilder();

                    sb.Append("<form id='tempForm' name='tempForm'  action='http://192.168.22.251:907/Mc/default.aspx?act=login' method='post' target='_blank' >");
                    sb.Append("<input type='hidden' name='UserName' value='" + userid.Text.Trim() + "'>");
                    sb.Append("<input type='hidden' name='Password' value='" + userpwd.Text + "'>");
                    sb.Append("<input type='hidden' name='Chknum' value=''>");
                    sb.Append("</form><script>document.getElementById('tempForm').submit();</script>");                    formStr = sb.ToString();

.aspx 页呢我这是直接就弹新页的

会不会是formstr默认值为空,而我点击按纽登陆以后跳转到了别的页面,formstr 的表单就不提交了

哦,确实是我刚才说的问题,formStr默认是string.Empty
<body>
<%=formStr %>
    <form id="form1" runat="server">
<div id="container">
          帐  号：<cc1:rtextbox id="userid" runat="server" fielderrormessage="请输入帐号" nulltype="notNull"
              validationgroup="a" width="120px" ValidationExpression="\w{4,20}" Zu="a" ExpressionErrorMessage="格式错误"></cc1:rtextbox></p>
      <p class="tips">请输入用户名</p>
      <p class="input">
          密  码：<cc1:rtextbox id="userpwd" runat="server" fielderrormessage="请输入密码" nulltype="notNull"
              textmode="Password" width="120px" zu="a"></cc1:rtextbox></p>
      <p class="tips">密码区分大小写
      </p>
</body>然后就是在imgclick事件里执行
   StringBuilder sb = new StringBuilder();

                    sb.Append("<form id='tempForm' name='tempForm'  action='http://192.168.22.251:907/Mc/default.aspx?act=login' method='post' target='_blank' >");
                    sb.Append("<input type='hidden' name='UserName' value='" + userid.Text.Trim() + "'>");
                    sb.Append("<input type='hidden' name='Password' value='" + userpwd.Text + "'>");
                    sb.Append("<input type='hidden' name='Chknum' value=''>");
                    sb.Append("</form><script>document.getElementById('tempForm').submit();</script>");                    formStr = sb.ToString();

你imgclick 的click 事件里都进行什么操作了

  if (userpwd.IsOk && userid.IsOk)
        {
            TBL_company_user tcu = new TBL_company_user();
            tcu.user_id = userid.Text.Trim();
            tcu.pwd = userpwd.Text.Trim();
            StringBuilder sb = new StringBuilder();            sb.Append("<form id='tempForm' name='tempForm'  action='http://192.168.22.251:907/Mc/default.aspx?act=login' method='post' target='_blank' >");
            sb.Append("<input type='hidden' name='UserName' value='" + userid.Text.Trim() + "'>");
            sb.Append("<input type='hidden' name='Password' value='" + userpwd.Text + "'>");
            sb.Append("<input type='hidden' name='Chknum' value=''>");
            sb.Append("</form><script>document.getElementById('tempForm').submit();</script>");            formStr = sb.ToString();
            DataTable dt = tcu.Select("comp_id,comp_name,user_level,state_email,is_guests,status, comp_id,user_id,pwd,country,contact_mail,website,city,province,comp_address,contact_mobile,contact_sex,contact_fax,contact_tel,contact_name,area ", "user_id=@user_id and pwd=@pwd  ");

            if (dt.Rows.Count > 0)
            {
                if (dt.Rows[0]["state_email"].ToString() != "1")
                {
                    MessageBox("您尚未通过邮件激活账号！"); return;
                }
                else  if (dt.Rows[0]["status"].ToString() == "0")
                {
                    MessageBox("此帐号正在审核中！"); return;
                }
                else if (dt.Rows[0]["status"].ToString() == "5")
                {
                    MessageBox("您的账号已经冻结，请联系我们的销售人员！"); return;
                }

                else
                {
                                      tcu.user_id = dt.Rows[0]["user_id"].ToString();
                    tcu.pwd = dt.Rows[0]["pwd"].ToString();
                    tcu.comp_id = int.Parse(dt.Rows[0]["comp_id"].ToString());
                    tcu.user_level = int.Parse(dt.Rows[0]["user_level"].ToString());
                    tcu.is_guests = dt.Rows[0]["is_guests"].ToString();
                    tcu.comp_name = dt.Rows[0]["comp_name"].ToString();
                    tcu.country = dt.Rows[0]["country"].ToString();


                 }
            else
            {
                MessageBox("帐号或密码不正确！");
            }
        }

你新建个页，按我写的代码写一次。你看看是什么效果应该是你click 事件中做什么操作了

Page.RegisterStartupScript("aaa","javascript:window.location.href(../usermgr/userConfig.asp)");
不跳

StringBuilder sb = new StringBuilder();
           sb.Append("<form id='tempForm' name='tempForm' action='http://192.168.22.251:907/Mc/default.aspx?act=login'  method='post' target='_blank' >");
           sb.Append("<input type='hidden' name='userName' value='admin'>");
           sb.Append("<input type='hidden' name='userPwd' value='1234567'>");
           sb.Append("<input type='hidden' name='Chknum' value=''></form><script>document.getElementById('tempForm').submit();</script>");
           //用js来实现页面跳转
            sb.Append("<script>window.location='xxx.aspx';</script>");
           formStr = sb.ToString();
xxx.aspx为你要跳转的页当然你也可以把window.location='xxx.aspx' 这句代码放到表单提交的js 中
