为什么在使用jquery读写表单输入时必须对字符串进行编码?

I am programatically reading data from a text input using standard Jquery like this:

我正在编程地使用标准Jquery从文本输入中读取数据，如下所示:

  var listName = $('#list').val();

and then I am adding a hidden input field into a form before submitting like this:

然后在提交之前，我在表单中添加了一个隐藏的输入字段:

var myForm = $("#myForm);
myForm.append('<input type="hidden" name="List" value="' + listName + '" />');

In one example, the value in the field is:

例如，字段中的值为:

Key Date & Times

so on the UI it looks like this

UI是这样的

<input type="hidden" name="MyList" value="Key Date & Times" />

when I submit the form using:

当我以下列方式递交表格:

var myForm = $("#myForm);
myForm.submit();

and check it on the asp.net-mvc server side i only see:

在asp.net-mvc服务器端，我只看到:

Key Date

being sent over. After some research, it was suggested to write some javascript to run the value through:

发送结束。在一些研究之后，建议编写一些javascript来运行该值:

encodeURIComponent()

After doing that and taking a look at the server side, I now see:

这样做并查看服务器端之后，我现在看到:

Key%20Date%20%26%20Times

How can I convert that back to

我如何将它转换回

Key Date & Times

on the C# asp.net-mvc server side? Or Seperately, if I am doing something wrong on the client side, please let me if you have any suggestions.

在c# asp.net-mvc服务器端?另外，如果我在客户方面做错了什么，如果您有什么建议，请告诉我。

My main question is why do i have to worry about encoding the value of a hidden input box in a form. I would have thought this would be taken care of for you.

我的主要问题是，为什么我要担心在表单中编码隐藏输入框的值。我本以为你会处理好这件事的。
