Question

关于我创建的表单的回发有一个奇怪的问题。答案可能很简单，但我似乎无法看到它。

我有一个表单，如果视频打开的页面无法正常工作，用户可以填写该表单。它根据所选的当前视频预先填充字段，并允许用户填写其他字段，并将电子邮件发送给我以获得支持。

问题这些字段已正确预填充，但其中一个字段'Page'虽然预先填充正确，但未将值传递给按钮提交方法。

客户端代码 （包括一些mootools javascript，这有效）

<asp:Panel ID="pnlVideoProblem" runat="server" Visible="false">
        <h2>Report a video/learning tool issue</h2>
        <div class="keyline"></div>
        <fieldset class="emailform">
            <ul>
                <li><label>Name <span class="error">*</span></label><asp:TextBox ID="txtVideoName" runat="server" MaxLength="60"></asp:TextBox>
                <asp:RequiredFieldValidator ID="RequiredFieldValidator33" runat="server" CssClass="error" ControlToValidate="txtVideoName" ErrorMessage="Required"></asp:RequiredFieldValidator></li>

            </ul>
            <asp:Button ID="btnSubmitVideoIssue" runat="server" CssClass="subbutton" Text="Submit report" OnClick="btnSubmitVideoIssue_Click" />
        </fieldset>
        <script type="text/javascript">
            window.addEvent('domready', function () {
                document.id('<%= txtVideoBrowser.ClientID %>').set('value', Browser.Platform.name + ", " + Browser.name + " " + Browser.version);
                document.id('<%= txtFlashVersion.ClientID %>').set('value', Browser.Plugins.Flash.version + "." + Browser.Plugins.Flash.build);
            });
        </script>
    </asp:Panel>

按钮的后退代码 （回发时没有重置值）

{
    if (CheckEmptyCaptcha() == false)
    {
        //this field is hidden in css and empty. if it has been filled in, then an automated way of entering has been used.
        //ignore and send no email.
    }
    else

        emailForm.From = new MailAddress(txtVideoEmail.Text.Trim(), txtVideoName.Text.Trim());
        emailForm.Subject = "[ERROR] - [VIDEO ISSUE] from " + txtVideoName.Text.Trim();
        emailForm.Body = sbMessage.ToString();

        emailForm.IsBodyHtml = true;
        bool sendSuccess = false;

        try

表单值

Name : User
Email : User@test.com
Other Field : aab123
Video Learning ID : 5546
Browser version : win, firefox 9
Flash version : 11.102
Page : https://www.awebsite.com/library/video/5546
Visible error messages : ewrwerwe

生成的电子邮件

Name : User
Email : user@test.com
Other Field : aab123
Video ID : 5546
Browser : win, firefox 9
Flash Version : 11.102
Url referrer : 
Visible error messages : ewrwerwe

视频ID和Page / Url推荐人填充（！IsPostBack）

（适用！的IsPostBack）

pnlVideoProblem.Visible = true;
if (!String.IsNullOrEmpty(Request.QueryString["vid"]))
{
    txtVideoID.Text = Request.QueryString["vid"];
}

if (!String.IsNullOrEmpty(Request.QueryString["other"]))
{
    txtOtherField.Text = Request.QueryString["other"];
    txtOtherField.ReadOnly = true;
}
txtVideoPage.Text = HttpUtility.UrlDecode(Request.QueryString["ref"]);
txtVideoPage.ReadOnly = true;

任何想法？我有一个砖墙，我可以根据答案的简单程度来反击。

Answer 1

如果TextBox的ReadOnly属性为“true”，则不会回发数据   例如，它实际上意味着TextBox是只读的   服务器端的立场（客户端更改将被忽略）。

如果您希望TB以“旧方式”只读：

TextBox1.Attributes.Add（“readonly”，“readonly”）

因为这不会影响服务器端功能。

Answer 2

解决了：）

经过一丝微弱的阳光，我记得我有这个

RewriteRule ^/pop/(.*[^/])/report-issue/([a-fA-F0-9]{32})-([0-9]+)$ /pop.aspx?tp=$1&pg=report-issue&vid=$2&other=$3&ref=%{HTTP_REFERER} [L]

作为重写规则，然后让我仔细看看表单字段是否实际上包含在回发中。瞧不起，他们不是。

我在querystring变量读取部分周围包装了一个！回发，它可以工作！

砖墙需要很厚。

感谢那些试图提供帮助的人！
