Javascript asp.net提交表单后如何获取post数据,javascript,c#,jquery,asp.net,forms,Javascript,C#,Jquery,Asp.net,Forms,我的asp.net中有以下表单： <html> <head> <script type="text/javascript"> function GetSampleModel() { try { var wldscan = new ActiveXObject("WebLogonDemoClient.WLDScan");

我的asp.net中有以下表单：

    <html>
<head>
    <script type="text/javascript">

            function GetSampleModel() {
                try {
                    var wldscan = new ActiveXObject("WebLogonDemoClient.WLDScan");

                    var Sl_No = wldscan.GetSl();
                    var sampleModel = wldscan.GetVerifyTemplate();
                    if (sampleModel.length == 0) {
                        alert("Something is Error!!!", "Error");
                    }
                    else { 
                        document.getElementById("scan").Sl.Value = Sl_No;
                        document.getElementById("scan").SampleModel.Value = sampleModel;
                        document.getElementById("scan").submit();
                    }
                }
                catch (err) {
                    alert("To verify with a fingerprint device, you should install the WebLogonDemoClient software first.", "Software Not Install Error");
                }
            }
        </script>


        <title>Logon</title>
    </head>
    <body onload="GetSampleModel()">
        <form name="scan" id="scan" method="Post" action="" runat="server">
            <input type="Hidden" name="SampleModel" value="">
            <input type="Hidden" name="Sl" value="">
        </form>
    </body>
    </html>

提交表单后，我尝试通过以下代码在另一个页面中获取提交的数据：

sl = Request.Form["Sl"];
 String SampleModel = Request.Form["SampleModel"];

但这两个变量中没有数据。我在哪里犯错？请帮帮我

NameValueCollection nvclc = Request.Form;

调试后，我看到变量的值如下所示：

http://localhost/finger/famverifyTX.aspx?name=18&appuser='RANA001'&ailogid='1'&depamount=50&sessid='28902343093145'&custno='18'

{__VIEWSTATE=%2fwEPDwUKLTE4MDU5MzAwNg9kFgICAw8WAh4GYWN0aW9uBUNmYW12ZXJpZnlUWC5hc3B4P25hbWU9JmFwcHVzZXI9JmFpbG9naWQ9JmRlcGFtb3VudD0mc2Vzc2lkPSZjdXN0bm89ZGRLaLIbf6gMRB5SeuUkSj7FHaf%2fRZQuSXp1AE1b4qHvCw%3d%3d&SampleModel=&Sl=&__VIEWSTATEGENERATOR=9EF55AFD}

我有以下代码：

 string[] keys = Request.Form.AllKeys;
        var value = "";
        for (int i = 0; i < keys.Length; i++)
        {
            // here you get the name eg test[0].quantity
            // keys[i];
            // to get the value you use
            value = Request.Form[keys[i]];
            Response.Write("Keys is " + keys[i] + " and value is " + value+"<br>");

        }

因此，SampleModel和Sl的值为零。如何从fmaVerifyTX.aspx页面获取此值？请帮帮我

以下代码适用于我：

NameValueCollection nvclc = Request.Form;

document.getElementById("Sl").setAttribute('value', Sl_No);
document.getElementById("SampleModel").setAttribute('value', sampleModel);
