方式一：
后台处理
[HttpPost]
public JsonResult SendEmail()
{
int success = 0;
int fail = 0;
int count = Convert.ToInt32(Request.Form["countnum"]);
for (int i = 0; i < count; i++)
{
if (i % 2 == 0)
success += 1;
else
fail += 1;
}
JsonResult jsonResult = new JsonResult
{
Data = new
{
successCount = success,
failCount = fail,
}
};
return Json(jsonResult);
}
前台输出
function OpenEmail1() {
$.ajax({
url: "/tblGroups/SendEmail",
type: 'post',
data: {
countnum: $("#hidCount").val()
},
beforeSend: function () {
$("#loading").show();
},
error: function () {
alert("出错了");
},
success: function (data) {
$("#lblSuccess").html(data.Data.successCount);
$("#lblFail").html(data.Data.failCount);
$("#loading").hide();
$("#emailDIV").show();
$("#fade").show();
}
});
}
方式二：
后台代码：
[HttpPost]
public JsonResult GetModel(FormCollection collection)
{
string Action = collection["action"].ToString();
string strid = Request.Form["id"].ToString();
Guid id = new Guid(strid);
return Json(GetGroupsModel(id));
}
/// <summary>
/// 返回一个实体
/// </summary>
/// <param name="gid">id</param>
/// <returns></returns>
private IEnumerable<tblGroups> GetGroupsModel(Guid gid)
{
var query = from g in db.tblGroups
where g.Id == gid
select new
{
Id = g.Id,
Name = g.Name,
Description = g.Description,
SumCount = (from m in db.tblMembers
where m.GroupId == g.Id
select m).Count()
};
return query.ToList().Select(C => new tblGroups
{
Id = C.Id,
Name = C.Name,
Description = C.Description,
CountNum = C.SumCount
});
}
前台代码：
function OpenWin(id) {
$("#light").show();
$("#fade").show();
$.ajax({
url: "/tblGroups/GetModel",
type: 'post',
data: {
action: "GetModel",
id: id
},
success: function (data) {
for (var i = 0; i < data.length; i++) {
$("#lblName").html(data[i].Name);
$("#lblCount").html(data[i].CountNum);
$("#hidCount").val(data[i].CountNum);
}
}
});
}
结果集是object类型循环输出
function sel() {
$.ajax({
url: "/Trace/select",
type: "post",
data: {
name: $("#selBatch").val()
},
success: function (data) {
var objs = data;
var str = "";
$("#tbd").html("");
for (var n in objs)
{
str += "<tr>";
str += "<td>" + objs[n].BatchID + "</td>";
str += "<td>" + objs[n].Path + "</td>";
str += "</tr>";
}
$("#tbd").html(str);
}
});
}
Ajax请求
function InitData(pageindx, ofile, otype) {
$.ajax({
url: '/Campaign/Ajax_Read', //请求地址
type: 'POST', //请求方法
dataType: 'json', //返回数据类型(json，xml，html)
data: { //传递参数
action: 'paging',
pagenum: pageindx,
orderFile: ofile,
orderType: otype
},
beforeSend: function () { //发送请求前
$("#loading").show();
},
error: function () { //出现错误时提示状态
alert("出错了");
},
complete: function() { //请求完成后
alert("请求完成后提示信息")
},
success: function(data) { //请求成功时返回数据
var objs = jQuery.parseJSON(data);
for (var i = 0; i < objs.length; i++) {
$("#lblSuccess").html(objs[i].successCount);
$("#lblFail").html(objs[i].failCount);
}
}
})
}
async设置异步同步并设置数组
function createRandomData() {
$.ajax({
url: '/Handler/JsonList.ashx',
type: 'POST',
async: false,
data: {
action: ''
},
success: function(responseText) {
var re = responseText.toJson();
var data123 = [];
$.each(re, function(i, n) {
data123.push({
Id: i + 1,
GroupName: n.gName,
Description: n.description,
Member: n.member,
Email: n.email
});
});
}
});
}
方式三
后台代码
DataSet ds = DbHelperSQL.Query(sql.ToString());
ArrayList tmp = new ArrayList();
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
tmp.Add("{Times:" + ds.Tables[0].Rows[i]["Times"] + "," +
"Totals:" + ds.Tables[0].Rows[i]["Totals"] + "," +
"Drinking:" + ds.Tables[0].Rows[i]["Drinking"] + "," +
"Surplus:" + ds.Tables[0].Rows[i]["Surplus"] + "}");
}
string jsonResult = "[" + string.Join(",", (string[])tmp.ToArray(typeof(string))) + "]";
return jsonResult;
前台代码
$.ajax({
async: false,
url: "@Url.Action("GetModel", "BarChart")",
type: 'post',
data: {
name: name,
area: area,
begin: begin,
end: end
},
success: function (data) {
var objs = eval(data);
for (var i = 0; i < objs.length; i++) {
dataTime.push(objs[i].Times);
dataDrinking.push(objs[i].Drinking);
dataSurplus.push(objs[i].Surplus);
}
}
});
后台object循环输出
ResultMessage<object> result = new ResultMessage<object>();
result = busi.GetListBatch();
string[] arr = result.Data as string[];
List<SelectListItem> select1 = new List<SelectListItem>();
select1.Add(new SelectListItem { Text = "请选择...", Value = "" });
for (int i = 0; i < arr.Length; i++)
{
select1.Add(new SelectListItem
{
Text = arr[i].ToString(),
Value = arr[i].ToString()
});
}
