JSON数据无法与web服务签名匹配

我似乎还是不能把这个弄到手工作。爱尝试了字符串数组对象数组字典。我可能格式化我的JSON不正确,但我使用的是labs\u JSON插件。如果我删除数据并测试它正确调用的webservice。我的代码如下所示:

HTML格式:

<div style="display: block; float: left;">
        <asp:Repeater ID="rptMenuRecipeCategories" runat="server">
            <HeaderTemplate>
                <div class="recipeChecklistHeader">Menu Recipe Categories</div>
                <ul id="menuRecipeCategories" class="connectedSortable">
            </HeaderTemplate>
            <ItemTemplate>
                <li id="item_<%# Container.ItemIndex + 1 %>" recipeCategoryId='<%# Eval("RecipeCategoryID") %>' >
                    <%# Eval("RecipeCategory") %>
                </li>
            </ItemTemplate>
            <FooterTemplate>
                </ul>
            </FooterTemplate>
        </asp:Repeater>
</div>
<div style="display: block; float: left">
        <asp:Repeater ID="rptAvailableMenuRecipeCategories" runat="server">
            <HeaderTemplate>
                <div class="recipeChecklistHeader">Available Menu Recipes</div>
                <ul id="availabeMenuRecipeCategories" class="connectedSortable">
            </HeaderTemplate>
            <ItemTemplate>
                <li id="item_<%# Container.ItemIndex + 1 %>" recipeCategoryId='<%# Eval("RecipeCategoryID") %>'>
                    <%# Eval("RecipeCategory") %>
                </li>
            </ItemTemplate>
            <FooterTemplate>
                </ul>
            </FooterTemplate>
        </asp:Repeater>
</div>

    $(function () {
        $("#menuRecipeCategories, #availabeMenuRecipeCategories").sortable({
            connectWith: '.connectedSortable',
            update: function (ev, ui) {
                //var result = $('#menuRecipeCategories').sortable('toArray');
                //updateSequenceNumber(result);
            }
        }).disableSelection();
    });

函数persistRecipeCategorisToJSON(){ var items=$('#menuRecipeCategories').sortable('toArray'); var字典数据=“”; var itemArray=新数组();

        for (i = 0; i <= items.length - 1; i++) {
            if (items[i].length == 0)
                continue;

            var item = $('#' + items[i])[0];
            var recipeCategoryId = item.attributes["recipeCategoryId"].nodeValue;
            itemArray[i] = recipeCategoryId;
        }

        persistPositionUsingAjax($.json.encode(itemArray));
    }

    $(document).ready(function () {
        $.ajaxSetup({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            dataType: "json"
        });
    });

    function persistPositionUsingAjax(jsonData) {
        var webServiceURL = '<%=ResolveUrl("~/UserControls/MenuRecipeChecklistService.asmx")%>' + '/UpdateMenuRecipeChecklist';
        $.ajax({
            // This is page.name/MethodName     
            url: webServiceURL,

            // This is the data (method arguments)
            data: jsonData,

            // This is the handler for success.     
            success: function (msg) {
                alert('success');
            }
        });
    }  

JSON码:

["1","2"]

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string UpdateMenuRecipeChecklist(*INPUT TYPE TO GO HERE*)
        {
            return "";
       }

****好的,伙计们。我已经解决了这个问题。JSON实验室插件的JSON格式似乎不正确。 我在PersistRecipeCategorisToJSON函数中添加了以下行:**

var args = { jsonData: itemArray };
persistPositionUsingAjax($.json.encode(args));

然后通过为对象指定一个名称来正确格式化JSON。 然后,我将webservice的方法签名更新为:

public string UpdateMenuRecipeChecklist(string[] jsonData)
