如何在readonly的文本框中获取值

I have a textbox.In its onclick iam calling a javascript fn to call calendar.Texbox is readonly. Clicking on textbox calendar is coming and value is showing in textbox. But on clicking submit button where I have written code to save, there i am not getting value in textbox. What may be the reason for that?

我有一个文本框。在其onclick iam中调用javascript fn来调用calendar.Texbox是readonly。单击文本框日历即将到来,值将显示在文本框中。但是点击提交按钮,我已经编写了代码保存,我没有在文本框中获得价值。可能是什么原因?

5 个解决方案

I suspect that your text box has the disabled attribute instead of readonly which prevents it from posting its value to the server.

我怀疑您的文本框具有disabled属性而不是readonly,这会阻止它将其值发布到服务器。

I had this problem too, there is a really simple workaround

我也有这个问题,有一个非常简单的解决方法

Instead of making the textbox ReadOnly using properties option. Do it thru the code behind adding this code:

而不是使用属性选项使文本框ReadOnly。通过添加此代码后面的代码来执行此操作:

YourTextBox.Attributes.Add("readonly", "readonly");

#3

You can get the value by using

您可以使用获取值

Request.Form[YourTextBox.UniqueID]

I'm guessing the textbox is disabled so that people have to use the calendar control to enter a date? The textbox is just for showing the selected date?

我猜测文本框已禁用,以便人们必须使用日历控件输入日期?文本框仅用于显示所选日期?

If you want the textbox to stay readonly (i.e. disabled client-side), have a hidden input that has the value you want to handle on the server is the way to go probably. So add an additional input for to the page. Use

如果您希望文本框保持只读(即禁用客户端),则可能有一个隐藏的输入具有您要在服务器上处理的值。因此,为页面添加其他输入。使用

<asp:HiddenField ... runat="server" />

So the client-side code that updates your readonly textbox will also update your hidden input.

因此,更新您的只读文本框的客户端代码也将更新您的隐藏输入。

if readonly property is true, its not break your .cs call. you can use this as always:

如果readonly属性为true,则不会破坏.cs调用。你可以像往常一样使用它:

here are your inputs:

这是你的输入:

<asp:TextBox ID="txtBraid" runat="server" Text="Im sooo readonly" ReadOnly="True"></asp:TextBox>
<asp:Label ID="lblBraid" runat="server" Text="Im gonna change, i promise"></asp:Label>

on .cs page put these to onClick function or something:

在.cs页面上将这些放到onClick函数或其他东西:

lblBraid.Text = txtBraid.Text;
