1.ViewBag对象是动态解析对象
@{ ViewBag.Title = "Insert"; } 不仅可以把单个的对象绑定到 ViewBag上,还可以直接绑定List
ViewBag.Category = db.Category.ToList(); 下面直接生成一个select
2.画面实体类对象传递
@model BlogMVC.Models.DataInfo
使用方式 @Model.Title,其中 Title 是 DataInfo类的字段
3.画面直接输出html源代码
@(new HtmlString(Server.UrlDecode(Model.Content)))
4.jquery的使用 之 单个值传递
string json = "{\"b\": \"" + result + "\"}"; return json; 画面上调用:
$.ajax({ type: "POST", url: "/AjaxAction/InsertBlog", data: { title: title, tag: tag, category: category, mcontent: mcontent }, dataType: "text", async: true, beforeSend: function () { //alert("beforeSend"); }, success: function (d) { // alert("succeed"); var jsons = eval("(" + d + ")"); if (jsons.b > 0) { alert("提交成功"); } else { alert("提交失败"); } } });
5.jquery的使用 之 datatable 数据集画面展示
public string SearchAction(string keywords,int pageIndex=1) { string json = ""; SqlParameter[]parms = new SqlParameter[]{ new SqlParameter("@keywords",keywords), new SqlParameter("@pageIndex",pageIndex), new SqlParameter("@pageSize",10) }; DataTable dt = SqlHelper.GetTable("usp_getDataManager", parms); Dictionary dict = new Dictionary (); if (dt!=null&&dt.Rows.Count > 0) { int count = (int)SqlHelper.ExecuteScalar("usp_getDataCountManager", new SqlParameter[] { new SqlParameter("@keywords", keywords) }); string jsonData = JsonConvert.SerializeObject(dt); dict.Add("jsonData", jsonData); dict.Add("dataCount", count); json = JsonConvert.SerializeObject(dict); } else { string jsonData = JsonConvert.SerializeObject(dt); dict.Add("jsonData", ""); dict.Add("dataCount", -1); json = JsonConvert.SerializeObject(dict); } return json; }
画面上的调用:
function ajaxQueryFunc(keywords, pageindex) { $.ajax({ type: "post", data: { keywords: keywords, pageindex: pageindex, type: "sc" }, url: "/AjaxAction/Search", dataType: "text", beforeSend: function () { //从tr 第2行到末尾的都要删除 var headr = $("#tab_data tr").first(); $("#tab_data").children().remove(); $("#tab_data").append(headr); }, success: function (d) { var jsons = eval("(" + d + ")"); var dataCount = jsons["dataCount"]; if (dataCount > 0) { showPagingDiv(dataCount, pageindex); var jsonData = jsons["jsonData"]; var data = eval(jsonData); var strTr = ""; for (cc in data) { if (typeof (data[cc]) == 'object') { strTr = strTr + " "; strTr = strTr + ""; strTr = strTr + ""; strTr = strTr + "" + data[cc]['DataId'] + ""; strTr = strTr + "" + data[cc]['Title'] + ""; strTr = strTr + "" + data[cc]['Click'] + ""; strTr = strTr + "" + data[cc]['Author'] + ""; strTr = strTr + "" + "2014-03-15 21:11:01" + ""; strTr = strTr + "" + data[cc]['Tags'] + ""; strTr = strTr + "修改排名 删除 "; strTr = strTr + " "; } } $("#tab_data").append(strTr); } else { alert("没有检索导数据"); } } }); }
