我可以有另一种内一种形式标记在ASP.net MVC RC2 [英] Can i have One form tag inside Another in ASP.net MVC RC2

问题描述

我目前正在开发的应用程序MVC2
我曾经想用多发表单标签我的应用程序
在我看来
我创建了具有删除对此我通过邮政做选项个人删除，所以我必须为每个按钮创建表单标签表。
我也希望用户给选项删除多发的记录，所以我为他们提供checkboxes.This形式应该有复选框，所有的所有值。
这样的形式得到呈现像这样

I am currently Developing application in MVC2 I have want to used mutiple form tags in My application In My View I have Created a table which has Delete option which i am doing through Post for Individual Delete so i have Create form tag for each button. i also want user to give option to delete mutiple records so i am providing them with checkboxes.This form should have all the values of checkboxes and all. so form gets render Like this

对于每一个删除按钮

 <form action="/Home/MutipleDelete" method="post">   
<input class="button " name="Compare" type="submit" value="Mutipledelete" style="margin-right:132px;"  />

<input id="chk1" name="chk1" type="checkbox" value="true" />

<form action="/Home/Delete" method="post"> 

    <input type="submit"  class="submitLink"  value="member1" />

     <input type="hidden" name="hfmem1" id="hfmem1" value="1"  />  

                 </form>
<input id="chk2" name="chk2" type="checkbox" value="true" />

<form action="/Home/Delete" method="post"> 

    <input type="submit"  class="submitLink"  value="member2" />

     <input type="hidden" name="hfmem2" id="hfmem2" value="2"  />  

                 </form>


           </form>

以下是行不通的。但如果我写我的code的形式呈现在这样

The following is not working . but IF i write my code that form renders in this way

    <form action="/Home/MutipleDelete" method="post">   

<input class="button " name="Compare" type="submit" value="Mutipledelete" style="margin-right:132px;"  />
</form>
<input id="chk1" name="chk1" type="checkbox" value="true" />

<form action="/Home/Delete" method="post"> 

    <input type="submit"  class="submitLink"  value="member1" />

     <input type="hidden" name="hfmem1" id="hfmem1" value="1"  />  

                 </form>
<input id="chk2" name="chk2" type="checkbox" value="true" />

<form action="/Home/Delete" method="post"> 

    <input type="submit"  class="submitLink"  value="member2" />

     <input type="hidden" name="hfmem2" id="hfmem2" value="2"  />  

                 </form>

it is working in Mozilla but not in IE.I have debug and Checked values in formcollection In contoller.What to do.?

推荐答案

在XHTML中，表单中的一个形式是不允许的，它并没有真正意义。

In XHTML, a form in a form is not allowed and it doesn't really make sense.

要完成什么你正在尝试做的，你应该在你的表使用简单的链接/按钮。这些可能，例如，发送删除的请求到服务器，并请求成功的完成时，也删除使用jQuery UI中的条目。

To accomplish what you are trying to do, you should use simple links/buttons in your table. These could, for example, send a 'delete' request to your server and, upon succesful completion of the request, also remove the entry from the UI using jQuery.

例如：

    [Authorize]
    [HttpPost]
    public JsonResult Delete(Guid id)
    {
         // do stuff, delete the item
         return Json(succeeded ? Id.ToString() : "error");
    }

视图

<a href="#" onclick="$.post('/Stuff/Delete/' + id, function(data) { deleteCallback(data); }); return false;">delete</a>

function deleteCallback(data)
{
  if(data=="error"){
    /* error handler for UI */
  }
  else {
    /*remove the entry from the user interface*/
  }
};

如果你想要做多删除，你不应该转移ID的列表中删除使用URL（因为在IE 2K的限制，它看起来讨厌），而是使用以下语法：

If you want to do multi-delete, you should not transfer the list of IDs to delete using the URL (because there is a 2k limitation in IE and it looks nasty), but instead use the following syntax:

arrayVariable = new Array(); 
// fill array with ids associated to checked checkboxes' entries
$.post('/Stuff/Delete/' + id, {'IdsToDelete' : arrayVariable }, function(data) { deleteCallback(data); }); return false;">

这可以自动序列化到一个真正的.NET名单，所以你只需要遍历整数或GUID的，或任何你的PK样子！列表

This can be automatically serialized to a real .NET list, so you will just have to iterate list of integers or GUIDs, or whatever your PKs look like!

编辑：这仍然是一个有点简化。出于安全原因，你应该保护自己免受CSRF（跨站请求伪造）。达林提供一个伟大的答案如何做到这一点。

This is still a bit simplified. For security reasons, you should protect yourself from CSRF (Cross-Site Request Forgery). Darin provided a great answer how to do that.

这将添加 [ValidateAntiForgeryToken] 到控制器的方法和观点都需要包含类似

This will add the [ValidateAntiForgeryToken] to your controller's method and the view will need to contain something like

var token = $('input[name=__RequestVerificationToken]').val();
$.post("/YourUrl", { 'IdsToDelete' : arrayVar, '__RequestVerificationToken': token }, function(data) { deleteCallback(data); });
