AJAX后多数据来ASP.Net MVC [英] AJAX Post Multiple Data to ASP.Net MVC

问题描述

我现在面临的问题，同时张贴通过AJAX的jQuery多个对象MVC 4控制器。它一直星期，但我似乎无法找到解决的办法。
我试了几种方法，有时filterModel对象为null，有时字符串参数为空（不事我就算字符串化，如果我指定的contentType与否）

我想要什么？
我想通过三个对象：1。filterModel 2.testparamA 3.testparamB
我应该怎么做才能通过全部三个物体MVC控制器？我需要什么数据写：所以我得到所有3个对象的值

？

最简单的控制器

  [HttpPost]
公共JsonResult测试（字符串testparamA，串testparamB，FilterModel过滤器）
{
    使用（RBSystemEntities库=新RBSystemEntities（））
    {
        返回JSON（新{
            DataList控件= repository.Items.Select（X =＆gt;新建{x.PKID，x.ItemName}）了ToList（）
            结果=OK
        }）;
    }
}
 

最简单的查看

  VAR filterModel = @ Html.Raw（Json.En code（新FilterModel（ITEMNAME，辣香肠比萨饼）））
// filterModel = JSON.stringify（filterModel）;功能TESTME（）{
    //发布JavaScript变量回控制器
    $阿贾克斯（{
        网址：'/菜单/测试，
        输入：POST，
        //的contentType：应用/ JSON的;字符集= UTF-8，
        数据：{
            过滤：filterModel，
            testparamA：'值'，
            testparamB：B值
        } //使用这个方法，我得到filterModel空控制器然而testparamA和testparamB具有价值
        数据：filterModel，//使用这个方法，我得到filterModel值，但我无法通过testparamA和testparamB
        成功：函数（结果）{
            // TODO：做的事结果
            警报（成功）;
        }
    }）;
}
TESTME（）;
 

最简单的FilterModel类

 公共类FilterModel
{
    公共FilterModel（）{}
    公共FilterModel（字符串filtercolumn，串filtervalue）
    {
        this.FilterColumn = filtercolumn;
        this.FilterValue = filtervalue;
        this.FilterColumnCriteria ==;
    }
    公共字符串FilterColumn {搞定;组; }
    公共字符串FilterValue {搞定;组; }
    公共字符串FilterColumnCriteria {搞定;组; }
}
 

解决方案

希望你不介意我张贴我的评论（这是有帮助的）作为一个答案......

如果您使用字符串化如下它应该工作...

  JSON.stringify（{FM：filterModel，TA：testparamA，TB：testparamA}）
 

I am facing problem while posting multiple objects via ajax jquery to MVC 4 controller. It has been weeks but I can't seem to find a solution. I tried several approaches, sometimes the filterModel object is null and sometimes string parameters are null (doesn't matter even if I stringify of if I specify contentType or not)

What I want? I want to pass three objects: 1. filterModel 2.testparamA 3.testparamB What should I do to pass all three objects to MVC controller? What do I need to write in data: so I get all 3 object values?

The simplest Controller

[HttpPost]
public JsonResult Test(string testparamA, string testparamB, FilterModel filter)
{
    using (RBSystemEntities repository = new RBSystemEntities())
    {
        return Json(new {
            DataList = repository.Items.Select(x => new {x.PKID, x.ItemName}).ToList(),
            Result = "OK"
        });
    }
}

The simplest View

var filterModel = @Html.Raw(Json.Encode(new FilterModel("ItemName", "Pepperoni Pizza")))
//filterModel = JSON.stringify(filterModel);

function testme() {
    // post the javascript variable back to the controller 
    $.ajax({
        url: '/Menu/Test',
        type: 'POST',
        //contentType: 'application/json; charset=utf-8',
        data: {
            filter: filterModel,
            testparamA: 'A value',
            testparamB: 'B value'
        }, // with this approach I get filterModel null in the controller however testparamA and testparamB has values
        data: filterModel, // with this approach I get values for filterModel but I can't pass testparamA and testparamB
        success: function (result) {
            // TODO: do something with the results
            alert('success');
        }
    });
}
testme();

The simplest FilterModel class

public class FilterModel
{
    public FilterModel() { }
    public FilterModel(string filtercolumn, string filtervalue)
    {
        this.FilterColumn = filtercolumn;
        this.FilterValue = filtervalue;
        this.FilterColumnCriteria = "=";
    }
    public string FilterColumn { get; set; }
    public string FilterValue { get; set; }
    public string FilterColumnCriteria { get; set; }
}

解决方案

Hope you don't mind me posting my comment (which was helpful) as an answer...

If you use stringify as follows it should work...

JSON.stringify({ fm: filterModel, ta: testparamA, tb: testparamA })
