html method=get 不将值传递给下一个 aspx 页面

我有一个简单的 html 页面，有 3 个文本框。

<form id="form1" method=get action="http://mysite.com/default.aspx" runat="server">
    <div>
        <input id="name" type="text" value="Amy" />
        <input id="email" type="text"  value="[email protected]"/>
        <input id="phone" type="text" value="2125552512" />
    </div>
    <input id="Submit1" type="submit" value="submit" />
</form>

现在，当它加载 default.aspx 时，我在 page_load 的 vb 后端中有此代码。

Dim tbName As TextBox = Page.FindControl("Name")
Dim tbPhone As TextBox = Page.FindControl("Phone")
Dim tbEmail As TextBox = Page.FindControl("Email")
If page.request("name") & "" <> "" AndAlso tbname IsNot Nothing Then
    tbname.text = page.request("name") 
End If
If page.request("email") & "" <> "" AndAlso tbEmail IsNot Nothing Then
    tbEmail.text = page.request("email") & ""
end If
If page.request("phone") & "" <> "" AndAlso tbphone IsNot Nothing Then
    tbPhone.text = page.request("phone") & ""
End If

页面已加载，但这些文本框为空。我做错了什么？

i have simple html page with 3 textboxes.

<form id="form1" method=get action="http://mysite.com/default.aspx" runat="server">
    <div>
        <input id="name" type="text" value="Amy" />
        <input id="email" type="text"  value="[email protected]"/>
        <input id="phone" type="text" value="2125552512" />
    </div>
    <input id="Submit1" type="submit" value="submit" />
</form>

Now when it loads default.aspx i have this code in the vb backend on page_load.

Dim tbName As TextBox = Page.FindControl("Name")
Dim tbPhone As TextBox = Page.FindControl("Phone")
Dim tbEmail As TextBox = Page.FindControl("Email")
If page.request("name") & "" <> "" AndAlso tbname IsNot Nothing Then
    tbname.text = page.request("name") 
End If
If page.request("email") & "" <> "" AndAlso tbEmail IsNot Nothing Then
    tbEmail.text = page.request("email") & ""
end If
If page.request("phone") & "" <> "" AndAlso tbphone IsNot Nothing Then
    tbPhone.text = page.request("phone") & ""
End If

The page loads but is these textboxes are empty. what am i doing wrong?

如果您希望能够在服务器端访问这些控件，则需要向每个控件添加 runat="server" 属性。

另外，您引用的 TextBox 类型是您没有使用的 ASP.NET 控件。添加 runat="server" 标记后，您将使用的是 HtmlInputText。

您可以通过使用 TextBox ASP.NET 控件而不是元素来使用 TextBox 类型：

<asp:TextBox ID="name" runat="server" Value="Amy" />

如果您的 ASP.NET 页面所做的只是处理请求从表单中，则无需引用任何文本框或输入控件 - 这是不可能的，因为它们不作为 ASP.NET 控件存在。您所需要做的就是从 Request.QueryString 读取值。

如果目的是让输入在 ASP.NET 页面上可见和/或可编辑，我建议将 HTML 表单移至 ASP.NET 页面中。

If you want to be able to access those controls serverside, you'll need to add the runat="server" attribute to each of them.

Also, the TextBox type you're referencing is the ASP.NET control, which you aren't using. What you'd be using, once you add the runat="server" tags is HtmlInputText.

You can use the TextBox type by using the TextBox ASP.NET control instead of the <input> elements:

<asp:TextBox ID="name" runat="server" Value="Amy" />

If all your ASP.NET page is doing is processing the request from the form, then there's no need to reference any textbox or input controls - it won't be possible since they don't exist as ASP.NET controls. All you need to do is read the values from Request.QueryString.

If the intent is for the inputs to be visible and/or editable once they're on the ASP.NET page, I'd recommend moving the HTML form into your ASP.NET page.
