通过字典控制器asp.net的MVC [英] pass dictionary to controller asp.net mvc

问题描述

我想通过类型的字典＆LT; INT，INT＆GT; 来通过Ajax后我控制器。 这里主要的原因是后可能有键值对1-3之间的位置（这些值都不被称为在编译时），并在将来有可能上升到5。

另外，在文章中，我要通过一些其他的数据，如ID和名称，这一切工作正常。

我将如何构建该辞典中的JavaScript，然后通过JQuery的帖子发送，并最终接受它的控制器来处理？

编辑2： 我已经决定只解决这个问题有一个职位的每个值，而不是试图通过一本字典。

编辑： 下面是我的源功能，所以你可以看到什么，我想：

 函数BindAddMenuItem（）{
        $（AddMenuItem）。点击（函数（五）{
            即preventDefault（）;

            //获取头标识的链接通过this.id删除addmenuitem
            VAR currentId = $（本）.attr（ID）取代（AddMenuItem，）。

            //获取itemnumber，了itemname，从文本框具有相同的标题ID itemdetails
            VAR restaurantId = jQuery.trim（$（＃RestaurantId）VAL（））;
            变种itemNumber = jQuery.trim（$（＃ItemNumber+ currentId）.VAL（））;
            变种了itemname = jQuery.trim（$（＃了itemname+ currentId）.VAL（））;
            变种itemDetails = jQuery.trim（$（＃ItemDetails+ currentId）.VAL（））;

            VAR成本=新的对象（）;
            //选取所有文本框带班头+ currentId
            $（头+ currentId）。每个（函数（一）{
                。VAR optionId = $（本）.attr（ID）取代（选项，）;
                费用[optionId] = $（本）.VAL（）;
            }）;


            $阿贾克斯（
            {
                键入：POST，
                网址：/菜单/ AddMenuItem
                数据：reastaurantId =+ restaurantId +与＆amp; menuHeaderId =+ currentId +与＆amp; itemNumber =+ itemNumber +与＆amp;了itemname =+了itemname +与＆amp; itemDetails =+ itemDetails +与＆amp;成本= +成本，
                数据类型：HTML，
                成功：函数（结果）{
                    VAR domElement = $（结果）;
                    $（＃MenuContainer中）replaceWith（domElement）。
                    VAR newNum = parseInt函数（itemNumber）+ 1;
                    $（＃ItemNumber+ currentId）.VAL（newNum）;
                    BindAllBehaviours（）;
                }
            }）;
        }）;

    }
 

解决方案

喜欢的东西（JavaScript的）

 字典=新的对象（）;
字典['12'] = 5;
字典['13'] = 6;
快译通['1000'] = 21;
快译通['9'] = 13;
字典['13'] = 48;

.post的$（'/ client.mvc / mypostaction /'，{myDictionary：字典}）;
 

INT，INT＆GT; 的属性类型

您就可以使用词典＆LT发布字典对象到控制器

 的ActionResult MyPostAction（词典＆LT;字符串，INT＆GT; myDictionary）

这是笔者的code第二次编辑：

我下面的工作，有当词典＆LT;字符串，INT＆GT; kvPairs 。 ＆LT; INT，INT＆GT; 不会毕竟​​上班

请您的文章，如：

  VAR字典=新的对象（）;
字典['13'] = 9;
字典['14'] = 10;
字典['2'] = 5;

.post的$（'controller.mvc /测试'，{'kvPairs：快译通}，功能（OBJ）{$（'＃输出）HTML（obj.Count）;}）;
 

I am wanting to pass a dictionary of type <int,int> to my controller via an Ajax post. The main reason here is the post may have between 1-3 key value pairs here (none of these values are known at compile time) and in the future it may go up to 5.

Also in the post I have to pass in some other data, such as Id and name, which all works as normal.

How would I construct this dictionay in the javascript then send it via the JQuery post and finally receive it on the controller to process?

Edit 2: I have decided to just solve this with a post for each value instead of trying to pass a dictionary.

EDIT: Here is my source for the function so you can see what I am trying:

function BindAddMenuItem() {
        $(".AddMenuItem").click(function (e) {
            e.preventDefault();

            //get header id from link by removing addmenuitem from this.id
            var currentId = $(this).attr("id").replace("AddMenuItem", "");

            //get itemnumber, itemname, itemdetails from textboxes with same header id
            var restaurantId = jQuery.trim($("#RestaurantId").val());
            var itemNumber = jQuery.trim($("#ItemNumber" + currentId).val());
            var itemName = jQuery.trim($("#ItemName" + currentId).val());
            var itemDetails = jQuery.trim($("#ItemDetails" + currentId).val());

            var costs = new Object();
            //select all textboxes with class "Header" + currentId
            $(".Header" + currentId).each(function (i) {
                var optionId = $(this).attr("id").replace("Option", "");
                costs[optionId] = $(this).val();
            });


            $.ajax(
            {
                type: "POST",
                url: "/Menu/AddMenuItem",
                data: "reastaurantId=" + restaurantId + "&menuHeaderId=" + currentId + "&itemNumber=" + itemNumber + "&itemName=" + itemName + "&itemDetails=" + itemDetails + "&costs=" + costs,
                dataType: "html",
                success: function (result) {
                    var domElement = $(result);
                    $("#MenuContainer").replaceWith(domElement);
                    var newNum = parseInt(itemNumber) + 1;
                    $("#ItemNumber" + currentId).val(newNum);
                    BindAllBehaviours();
                }
            });
        });

    }

解决方案

Something like (javascript)

dict = new Object();
dict['12'] = 5;
dict['13'] = 6;
dict['1000'] = 21;
dict['9'] = 13;
dict['13'] = 48;

$.post('/client.mvc/mypostaction/', { myDictionary: dict });

You can then post the dict object to your controller using a Dictionary<int, int> as property type.

ActionResult MyPostAction(Dictionary<string, int> myDictionary)

---

edit from author's code second time:

The following works for me, when having a Dictionary<string, int> kvPairs. <int, int> isn't going to work after all.

Make your post like:

var dict = new Object();
dict['13'] = 9;
dict['14'] = 10;
dict['2'] = 5;

$.post('controller.mvc/Test', { 'kvPairs': dict }, function(obj) { $('#output').html(obj.Count); });
