Ajax无法使用带有2D数组参数的C＃控制器操作

Question

My Ajax is not hitting my controller action. What could be the reason?

My Controller Action

 public ActionResult Save_Data(string [][] rosterArray, int Pricelist_Id, int Group_Id)

My Ajax

$.ajax({
    url: '@Url.Action("Save_Data", "PriceListMaster")',
    type: 'Post',
    async: false,
    contentType: 'application/json',
    dataType: "json",
    data: {  "rosterArray": rosterArray, "Pricelist_Id": "2", "Group_Id": $("#Group_Id").val() },
    //data: JSON.stringify({ "Item_Code": Item_Code, "IPD_Price": IPD_Price, "OPD_Price": OPD_Price, "EMS_Price": EMS_Price }),
    success: function (data) {
        debugger
        if (data.success)
        {
            alert('Data Saved Successfully.');
            location.reload();
        } else {
            alert(data.error_msg);
        }
    }
}

Answer 1

If you are using type: 'Post' in AJAX, that means you need to add a Request type in Controller.

Try using this in controller,

[HttpPost]
public ActionResult Save_Data(string [][] rosterArray, int Pricelist_Id, int Group_Id)

Use httpPost in the Method for define type of response.

at client side

$.ajax({
    url: '@Url.Action("Save_Data", "PriceListMaster")',
    type: 'Post',
    async: false,
    contentType: 'application/json',
    dataType: "json",
    data: {  "rosterArray": JSON.stringify(rosterArray), "Pricelist_Id": "2", "Group_Id": $("#Group_Id").val() },
    //data: JSON.stringify({ "Item_Code": Item_Code, "IPD_Price": IPD_Price, "OPD_Price": OPD_Price, "EMS_Price": EMS_Price }),
    success: function (data) {
        debugger
        if (data.success)
        {
            alert('Data Saved Successfully.');
            location.reload();
        } else {
            alert(data.error_msg);
        }
    }
}

and your controller code can be like this:

[HttpPost]
public ActionResult Save_Data(string rosterArray, int Pricelist_Id, int Group_Id)
{
    string [][] convertedArray = JsonConvert.DeserializeObject<string [][]>(rosterArray);
}

Hope this works Note: But you need to incude using Newtonsoft.Json;
