如何使用ajax.actionlink获取formcollection [英] How to get formcollection using ajax.actionlink

问题描述

我有一个带有以下代码的控制器:

I have a controller with the codes like this:

[AcceptVerbs("POST")]
public ActionResult Create(FormCollection collection)
{
    //why is that the collection is null?
}

我正在使用ajax.actionlink调用此操作.

I am calling this action using the ajax.actionlink.

我的问题是集合为null，这与我是否使用commit(input)按钮不同 表单集合具有值.

my problem is the collection is null, unlike if i use the submit(input) button the formcollection has values.

推荐答案

FormCollection has a default binder associated with it which always initializes the collection and you should never get null. It is more likely that you have an empty collection when using Ajax.ActionLink in contrast to when using a form submit button. This is because the ActionLink method doesn't POST any form values when it performs the AJAX request.
