使用动作链接将文本框的值从视图传递到控制器 [英] pass value of a textbox from view to controller using actionlink

问题描述

在我的表单中，我有一个如下所示的文本框

In my form I have a textbox as below

@Html.TextBox("first_name")

我需要通过操作链接将此文本框的值传递给控制器​​.

I need to pass the value of this textbox to controller through a actionlink.

我尝试了以下

@Html.ActionLink("View", "view_Details", new { name = first_name})

但这给出了错误

名字"在当前上下文中不存在

"first_name" does not exist in the current context

是否可以使用Actionlink?

Is this possible using a Actionlink?

我的控制器签名是

public ActionResult view_Details(string name)
     {
            return View();
     }

已编辑

 @Html.ActionLink("View", "view_Details", new { name = getname()})

 <script type="text/javascript">
      function getname() {
           return $("#first_name").val();
       }
</script>

我尝试了上面的代码.它也给错误

I tried above code. Its also giving error

getname()在当前上下文中不存在

getname() does not exist in the current context

推荐答案

您需要javascript/jquery来获取文本框的值，然后更新要重定向到的URL

You need javascript/jquery to get the value of the textbox and then update the url you want to redirect to

HTML

@Html.ActionLink("View", "view_Details", new { id = "myLink" }) // add id attribute

脚本

$('#myLink').click(function() {
  var firstname = $('#first_name').val(); // get the textbox value
  var url = $(this).attr('href') + '?name=' + firstname; // build new url
  location.href = url; // redirect
  return false; // cancel default redirect
});

旁注:进一步编辑后，收到该错误的原因是剃刀代码(@Html.ActionLink()在发送到视图之前已在服务器上解析，但是getname()是不存在的客户端方法在那时-即在当前上下文中不存在

Side note: further to you edit, the reason you receive that error is that razor code (the @Html.ActionLink() is parsed on the server before its sent to the view but getname() is a client side method which does not exist at that point - i.e it does not exist in the current context
