首先下载这个 JavaScript 代码，JSON2.js，它将帮助我们将对象序列化为字符串。
在我的示例中，我通过 Ajax 发布 jqGrid 的行：
var commissions = new Array();
// Do several row data and do some push. In this example is just one push.
var rowData = $(GRID_AGENTS).getRowData(ids[i]);
commissions.push(rowData);
$.ajax({
type: "POST",
traditional: true,
url: '<%= Url.Content("~/") %>' + AREA + CONTROLLER + 'SubmitCommissions',
async: true,
data: JSON.stringify(commissions),
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function (data) {
if (data.Result) {
jQuery(GRID_AGENTS).trigger('reloadGrid');
}
else {
jAlert("A problem ocurred during updating", "Commissions Report");
}
}
});
现在在控制器上：
[HttpPost]
[JsonFilter(Param = "commissions", JsonDataType = typeof(List<CommissionsJs>))]
public ActionResult SubmitCommissions(List<CommissionsJs> commissions)
{
var result = dosomething(commissions);
var jsonData = new
{
Result = true,
Message = "Success"
};
if (result < 1)
{
jsonData = new
{
Result = false,
Message = "Problem"
};
}
return Json(jsonData);
}
创建一个 JsonFilter 类（感谢 JSC 参考）。
public class JsonFilter : ActionFilterAttribute
{
public string Param { get; set; }
public Type JsonDataType { get; set; }
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
{
string inputContent;
using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
{
inputContent = sr.ReadToEnd();
}
var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
filterContext.ActionParameters[Param] = result;
}
}
}
创建另一个类，以便过滤器可以将 JSON 字符串解析为实际的可操作对象：这个类 comissionsJS 是我的 jqGrid 的所有行。
public class CommissionsJs
{
public string Amount { get; set; }
public string CheckNumber { get; set; }
public string Contract { get; set; }
public string DatePayed { get; set; }
public string DealerName { get; set; }
public string ID { get; set; }
public string IdAgentPayment { get; set; }
public string Notes { get; set; }
public string PaymentMethodName { get; set; }
public string RowNumber { get; set; }
public string AgentId { get; set; }
}
我希望这个例子有助于说明如何发布一个复杂的对象。
