jquery 反序列化问题

var saveClick = function(){
    if($("#Name").val() == ''){
                    //alert('分类名称不能为空！');
                    //return;
    }
    //var arry = new Array();
    //arry.push({FDLabelName:""+$('#Name').val()+"",FDLableDescript:""+$('#Remark').val()+""});
    var str = '';
    str = '{\"p1\":[{FDLabelName:"'+$('#Name').val()+'"",FDLableDescript:"'+$('#Remark').val()+'"}],"p2":[';
    $.each($("input:[type=checkbox]"),function(){
        if(this.checked){
            //arry.push({"FDFirstMenuID":this.name,"FDSecondMenuID":this.id});
            str += '{FDFirstMenuID:'+this.name+',FDSecondMenuID:'+this.id+'},';
        }
    });
    str = str.substring(0,str.length-1) + ']}';
    //var data = {'p1':[{FDLabelName:""+$('#Name').val()+"",FDLableDescript:""+$('#Remark').val()//+""}],'p2'[arry.toString()]};
    var datas ={"p1":[{FDLabelName:"阿萨德",FDLableDescript:"对方"}],"p2":[{FDFirstMenuID:90,FDSecondMenuID:26},{FDFirstMenuID:90,FDSecondMenuID:27}]}
    $.ajax({
        type:'POST',
        contentType:'application/json',
        url:'../WebsiteEmbeddingLabelService.asmx/SaveWebsiteEmbeddingLabel',
        dataType:'json',
        data:JSON.stringify(str)//JSON.stringify(arry.toString())//为什么不能跳到服务里执行服务方法，而如果用datas替代str却可以,但都是json 格式    });
}

后台web服务代码:

[WebMethod]
    public void SaveWebsiteEmbeddingLabel(List<WebsiteEmbeddingLabelData> p1, List<WebsiteEmbeddingLabelIncludeSysMenusData> p2)
    {
        object p = p1;
        object pp = p2;
    }

我前台拼接字符串成json格式为什么不能到服务方法里,而如果我用红色字体部分却可以,请教高手,谢谢

FDLabelName FDLableDescript 对应WebsiteEmbeddingLabelData实体字段
FDFirstMenuID FDSecondMenuID 对应WebsiteEmbeddingLabelIncludeSysMenusData实体字段
另外请教是否有替代字符串 拼接的方法 谢谢

两个json字符串 用变量拼接都就不行 ？
