如何将 TextBox 的值作为 ActionLink 的参数发送？

我需要使用 Html.TextBoxFor

<%= Html.TextBoxFor(m => m.SomeField)%>
<%= Ajax.ActionLink("Link Text", "MyAction", "MyController", new { foo = "I need here the content of the textBox, I mean the 'SomeField' value"}, new AjaxOptions{ UpdateTargetId = "updateTargetId"} )%>

控制器/操作如下所示：

public class MyController{
   public ActionResult MyAction(string foo)
   {      
      /* return your content */   
   }
}

使用 MVC 2.0

How can I send the value of the TextBox as a parameter of the ActionLink?

I need to use the Html.TextBoxFor

The Contoller/Actions looks like this:

public class MyController{
   public ActionResult MyAction(string foo)
   {      
      /* return your content */   
   }
}

如何将 TextBox 的值作为 ActionLink 的参数发送？

将输入字段值（例如文本框）发送到服务器的语义上正确的方法是使用 html

而不是链接：

<% using (Ajax.BeginForm("MyAction", "MyController", new AjaxOptions { UpdateTargetId = "updateTargetId" })) { %>
    <%= Html.TextBoxFor(m => m.SomeField) %>
    <input type="submit" value="Link Text" />
<% } %>

现在，在控制器操作中，您将自动获取用户输入的 SomeField 输入：

public class MyController: Controller
{
    public ActionResult MyAction(string someField)
    {      
       /* return your content */   
    }
}

当然，您可以通过坚持使用 ActionLink 来尝试违反标记语义和 HTML 的工作方式，即使它是错误的。在这种情况下，您可以执行以下操作：

<%= Html.TextBoxFor(m => m.SomeField) %>
<%= Html.ActionLink("Link Text", "MyAction", "MyController", null, new { id = "myLink" }) %>

然后在单独的 javascript 文件中使用 jQuery 以不显眼的方式 AJAX 化此链接：

$(function() {
    $('#myLink').click(function() {
        var value = $('#SomeField').val();
        $('#updateTargetId').load(this.href, { someField: value });
        return false;
    });
});

How can I send the value of the TextBox as a parameter of the ActionLink?

The semantically correct way of sending input fields values (such as textboxes) to a server is by using an html <form> and not links:

<% using (Ajax.BeginForm("MyAction", "MyController", new AjaxOptions { UpdateTargetId = "updateTargetId" })) { %>
    <%= Html.TextBoxFor(m => m.SomeField) %>
    <input type="submit" value="Link Text" />
<% } %>

Now in your controller action you will automatically get the value of the SomeField input entered by the user:

public class MyController: Controller
{
    public ActionResult MyAction(string someField)
    {      
       /* return your content */   
    }
}

You could of course try to violate the markup semantics and the way HTML is supposed to work by insisting on using an ActionLink even if it is wrong. In this case here's what you could do:

<%= Html.TextBoxFor(m => m.SomeField) %>
<%= Html.ActionLink("Link Text", "MyAction", "MyController", null, new { id = "myLink" }) %>

and then in a separate javascript file unobtrusively AJAXify this link using jQuery:

$(function() {
    $('#myLink').click(function() {
        var value = $('#SomeField').val();
        $('#updateTargetId').load(this.href, { someField: value });
        return false;
    });
});
