http://blog.csdn.net/lonestar555/article/details/10192595/

 

 

// 方式一
var _list = {};

for (var i = 0; i < checkedRow.length; i++) {
    _list["selectedIDs[" + i + "]"] = checkedRow[i].ID;
}

$.ajax({
    url: '@Url.Action("SetCallBackStatus")',
    //data: { "selectedIDs": _list },
    data: _list,
    dataType: "json",
    type: "POST",
    //traditional: true,
    success: function (responseJSON) {
        // your logic
        alert('Ok');
    }
});

在action中的参数以数组方式接收数据

 一、表单方式

1、提交Form

<form action="../../test/test" method="post">

<select name="list_Number" id="list_Number" size="10"  multiple="multiple">
<option value="4">04</option>
<option value="2">02</option>
<option value="3">03</option>
</select>

</form>

 

[HttpPost]
        public ActionResult Test(string[] listNumber){

return View();
}

提交前必须选择所有列表：

$("#list_LotteryNumber > option").attr("selected", true);

 2、ajax提交

在ajax的data参数中加上：

 

$("form").serialize()

 

data: $("form").serialize(),

 

二、ajax提交数组参数

 

 

 

     var parm = {
                capital: "capital",
                arr: [  "c1","c2", "c3"],
                data: Math.random()
            };
            var p2 = $.param(parm, true);
//   或         var parm3 = "arr=c1&arr=c2&arr=c3&data=" + Math.random();

//            debugger
            $.ajax({
                type: "post",
                url: '/Home/AjaxArray',
                async: false,
                data: p2,
                success: function (data, txtStatus) {
                    alert(" 成功!");
                }
            });

 

 

    [HttpPost]          public ActionResult AjaxArray(string data , List<string> arr)          {              ViewBag.Message = "提交数组参数。";                return Json("");          }
[HttpPost]
        public ActionResult AjaxArray(string data , List<string> arr)
        {
            ViewBag.Message = "提交数组参数。";

            return Json("");
        }
