AJAX的調(diào)用方式實(shí)例

本篇內(nèi)容主要講解“AJAX的調(diào)用方式實(shí)例”，感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷，實(shí)用性強(qiáng)。下面就讓小編來(lái)帶大家學(xué)習(xí)“AJAX的調(diào)用方式實(shí)例”吧!

實(shí)例一：省份-城市的聯(lián)級(jí)下拉框 

利用AJAX來(lái)獲取數(shù)據(jù)實(shí)現(xiàn)聯(lián)級(jí)下拉框，當(dāng)省份下拉框的選項(xiàng)發(fā)生變化時(shí)，城市的選項(xiàng)對(duì)應(yīng)變化，效果如圖：

我們首先來(lái)實(shí)現(xiàn)后臺(tái)，先將數(shù)據(jù)準(zhǔn)備好了在實(shí)現(xiàn)前臺(tái)獲取數(shù)據(jù)，【考慮：當(dāng)我們頁(yè)面登錄的時(shí)候，我們需要獲取的數(shù)據(jù)】： 1).省份框中的省份; 2).因?yàn)榈卿洉r(shí)省份框的第一項(xiàng)選中，所以還需要第一個(gè)省份所對(duì)應(yīng)的城市名，好了，需求知道了，代碼就好寫(xiě)了，直接貼上后臺(tái)代碼：

protected void Page_Load(object sender, EventArgs e)          {              if (Request.QueryString["provid"] != null)              {                  //首先獲取傳遞過(guò)來(lái)的參數(shù)值                  string provId = Request.QueryString["provid"].ToString();                   //查詢(xún)所有城市                  string sqlprov = "select * from Provice";                  SqlDataReader reader = DbHelperSQL.ExecuteReader(sqlprov);                  string resultProv = "";                  while (reader.Read())                  {                      string id = reader[0].ToString();                      string provName = reader[1].ToString();                       //字符串拼接，為了前臺(tái)獲取時(shí)可以切分獲取對(duì)應(yīng)數(shù)據(jù)，用 '|' 來(lái)隔離 各個(gè)省份                      resultProv += "|" + string.Format("{0},{1}", id, provName);                  }                  reader.Close();                   //根據(jù)省份框的ID來(lái)獲取對(duì)應(yīng)的城市名                  string sqlcity =string.Format("select * from City where Proid='{0}'",provId);                  SqlDataReader readercity = DbHelperSQL.ExecuteReader(sqlcity);                  string resultCity = "";                  while (readercity.Read())                  {                      string cityId = readercity[1].ToString();                      string cityName = readercity[2].ToString();                       //同樣用字符串拼接 用 '|' 來(lái)隔離 同一省份 的各個(gè)城市                      resultCity += "|" + string.Format("{0},{1}", cityId, cityName);                  }                   //去除第一個(gè) '|' ,并且在最后拼接上 '&' 來(lái)區(qū)分省份和城市                  resultProv = resultProv.Substring(1) + "&";                   //最后的結(jié)果形式為【id,省份名|id2,省份名2|....&id,城市名|id2,城市名2|.....】                  string result = resultProv + resultCity.Substring(1);                   Response.Write(result);                  Response.End();              }          }

后臺(tái)代碼其實(shí)很簡(jiǎn)單，就是根據(jù)傳過(guò)來(lái)的參數(shù)從數(shù)據(jù)庫(kù)獲取對(duì)應(yīng)的數(shù)據(jù)，但是這里我們把獲取到得數(shù)據(jù)最后都用字符串拼接起來(lái)了，而且是有規(guī)律的拼接，這是為什么呢？其實(shí)在注釋上已經(jīng)講明了，就是為了方便前臺(tái)獲取對(duì)應(yīng)的數(shù)據(jù)了，因?yàn)槲覀兪鞘褂煤笈_(tái)返回文本形式的數(shù)據(jù)，這就是為什么我們拼接字符串了。。

接下來(lái)我們來(lái)實(shí)現(xiàn)前臺(tái)，前臺(tái)主要的任務(wù)就是獲取后臺(tái)返回的數(shù)據(jù)，并實(shí)現(xiàn)綁定......也是分塊貼上代碼

//實(shí)例化XmlHttpRequest對(duì)象   var xhr = null;          function CreateXhr() {              if (window.ActiveXObject)               {                  try                 {                      xhr = new ActiveXObject("Microsoft.XMLHTTP");                  }                  catch (e)                   {                      try                     {                          xhr = new ActiveXObject("Msxml2.XMLHTTP");                      }                      catch (e)                       {                          xhr = null;                      }                  }              }              if (window.XMLHttpRequest) {                  xhr = new XMLHttpRequest();              }               return xhr;          }

當(dāng)頁(yè)面載入時(shí)，實(shí)現(xiàn)省份框以及第一個(gè)省份對(duì)應(yīng)的城市框的綁定，代碼：

//載入綁定省份          function getLoadProv() {             CreateXhr();             xhr.onreadystatechange = WatchState;             xhr.open("get", "getProvCity.aspx?provid=1&time=" + new Date());             xhr.send(null);         }          //監(jiān)聽(tīng)載入綁定時(shí)狀態(tài)         function WatchState() {             if (xhr.readyState == 4 && xhr.status == 200) {                 //1,**|2,**&1,##|2,##                 var result = xhr.responseText;                 var provs = result.split('&')[0].split('|');                 var citys = result.split('&')[1].split('|');                  //省份下拉框清空                 document.forms[0].prov.length = 0;                  //綁定省份框                 for (var i = 0; i < provs.length; i++) {                     var prov = provs[i].split(',');                     //實(shí)例化一個(gè)選項(xiàng)                     var op = new Option();                     op.value = prov[0];                     op.text = prov[1];                     document.forms[0].prov.options.add(op);                 }                  //城市下拉框清空                 document.forms[0].city.length = 0;                  //綁定城市框                 for (var j = 0; j < citys.length; j++) {                     var city = citys[j].split(',');                     var op = new Option();                     op.value = city[0];                     op.text = city[1];                     document.forms[0].city.options.add(op);                 }                             }         }

當(dāng)省份框的選項(xiàng)發(fā)生變化時(shí)實(shí)現(xiàn)聯(lián)級(jí)變化，代碼：

//獲取城市  function GetCity() {           //獲取省份框選中的值      var provId = document.forms[0].prov.value;       CreateXhr();      xhr.onreadystatechange = UpdateCity;      xhr.open("get", "getProvCity.aspx?provid=" + provId + "&time=" + new Date());      xhr.send(null);  }   //修改城市下拉框內(nèi)容  function UpdateCity() {      if (xhr.readyState == 4 && xhr.status == 200) {          var result = xhr.responseText;          var citys = result.split('&')[1].split('|');          //城市下拉框清空          document.forms[0].city.length = 0;           //綁定城市框          for (var j = 0; j < citys.length; j++) {              var city = citys[j].split(',');              var op = new Option();              op.value = city[0];              op.text = city[1];              document.forms[0].city.options.add(op);          }                      }

前臺(tái)html代碼：

html   <body>      <form id="form1" runat="server">      <div>          <select id="prov" onchange="GetCity();">          </select>          <select id="city">          </select>      </div>      </form>  </body>

實(shí)例二：利用$.get，$.post方法獲取當(dāng)前時(shí)間

$.get():

由于實(shí)例相當(dāng)簡(jiǎn)單，直接上所有代碼：

protected void Page_Load(object sender, EventArgs e)         {             string time = "";             //Get             if (Request.QueryString["time"]!=null)             {                 time = "Get:"+ Request.QueryString["time"].ToString();             }             //Post             if (Request.Form["time"] != null)             {                 time = "Post:" + Request.Form["time"].ToString();             }              Response.Write(time + "  現(xiàn)在：" + DateTime.Now.ToString());             Response.End();         }

前臺(tái)獲取時(shí)間

<script src="../Scripts/jquery-1.8.0.js" type="text/javascript"></script>   <script type="text/javascript">       $(function () {           //參數(shù)：直接在頁(yè)面之后加？拼加           $("#btnGet").click(function () {               $.get("data.aspx?time=" + new Date(), Succeed);           });            //參數(shù)：使用鍵值來(lái)表示需要傳遞的參數(shù)           $("#btnPost").click(function () {               $.post("data.aspx", { time: new Date() }, Succeed);           });       });        function Succeed(result) {           $("#tbShow").val(result);       }   </script>

<body>     <form id="form1" runat="server">         <div>           <input type="text" id="tbShow"/>           <input type="button" id="btnGet" value="get方法" />           <input type="button" id="btnPost" value="post方法" />           <input type="button" id="btnAjax" value="ajax方法" />         </div>     </form> </body>

實(shí)例三：使用$.ajax實(shí)現(xiàn)獲取后臺(tái)數(shù)據(jù)，后臺(tái)返回?cái)?shù)據(jù)格式為text，json，xml三種類(lèi)型

3).jqXHR:包含XmlHttpRequest對(duì)象

dataType：服務(wù)器響應(yīng)的數(shù)據(jù)類(lèi)型，默認(rèn)將智能判斷

其余參數(shù)詳情參見(jiàn)：http://www.w3school.com.cn/jquery/ajax_ajax.asp

1>.test格式 --獲取時(shí)間的時(shí)，分，秒

后臺(tái)代碼：

public partial class textData : System.Web.UI.Page     {         protected void Page_Load(object sender, EventArgs e)         {             string hour = DateTime.Now.Hour.ToString();             string minute = DateTime.Now.Minute.ToString();             string second = DateTime.Now.Second.ToString();              string textStr = hour + "/" + minute + "/" + second;              Response.Write(textStr);              Response.End();         }     }

前臺(tái)獲取代碼：

<script src="../Scripts/jquery-1.8.0.js" type="text/javascript"></script>  <script type="text/javascript">      $(function () {          $("#btnText").click(function () {              $.ajax({                  url: "textData.aspx",                  type: "get",                  dataType: "text",                  success: textSucceed,                  error: Error              });          });       });       //成功      function textSucceed(result) {          $("#tbShow").val(result);      }       //錯(cuò)誤函數(shù)      function Error() {          alert("Error!!!");      }  </script>

2>.Json格式 --獲取時(shí)間的時(shí)，分，秒

我們需要在后臺(tái)返回Json格式的數(shù)據(jù)，添加一個(gè)dll鏈接庫(kù)，類(lèi)似.Net中處理Json數(shù)據(jù)的API ，如圖：

Json格式后臺(tái)代碼：

Json后臺(tái)   //添加引用   using Newtonsoft.Json;   namespace AJAX.Json   {       public partial class jsonData : System.Web.UI.Page       {           protected void Page_Load(object sender, EventArgs e)           {               string hour = DateTime.Now.Hour.ToString();               string minute = DateTime.Now.Minute.ToString();               string second = DateTime.Now.Second.ToString();                  //匿名類(lèi)型               var time = new { h = hour, m = minute, s = second };                  //轉(zhuǎn)Json格式               var jsonStr = JsonConvert.SerializeObject(new[] { time });                  Response.Write(jsonStr);                  Response.End();           }       }   }

Json格式前臺(tái)代碼：

<script src="../Scripts/jquery-1.8.0.js" type="text/javascript"></script>      <script type="text/javascript">          $("#btnJson").click(function () {              $.ajax({                  url: "jsonData.aspx",                  type: "get",                  dataType: "json",                  success: jsonSuccess,                  error: Error              });          });           //成功          function jsonSuccess(result) {              //[{h:10,m:20,s:30}]              //key:數(shù)組元素下標(biāo)-此時(shí)為0              //value:{ h:10,m:20,s:30 }              $.each(result, function (key, value) {                  var h = value.h;                  var m = value.m;                  var s = value.s;                  $("#tbShow").val(h + ":" + m + ":" + s);              });          }                   //錯(cuò)誤函數(shù)          function Error() {              alert("Error!!!");          }      </script>

3>.xml格式--獲取用戶(hù)名，出生年月

Xml格式后臺(tái)代碼：

//添加引用  using System.Xml;   namespace AJAX.Ajax_Xml  {      public partial class XmlData : System.Web.UI.Page      {          protected void Page_Load(object sender, EventArgs e)          {              string name = "zld";              string birth = "1990-1-8";               //第一種：直接字符串拼接              string xmlStr = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><root><Name>" + name + "</Name><Birth>" + birth + "</Birth></root>";               //第二種：XmlDocument創(chuàng)建               //創(chuàng)建文檔              XmlDocument xmlDocument = new XmlDocument();              //文檔頭聲明              XmlDeclaration xd = xmlDocument.CreateXmlDeclaration("1.0","utf-8",null);              xmlDocument.AppendChild(xd);               //添加根節(jié)點(diǎn)              XmlElement root = xmlDocument.CreateElement("root");              xmlDocument.AppendChild(root);               //給根節(jié)點(diǎn)添加子節(jié)點(diǎn)              XmlElement node1 = xmlDocument.CreateElement("Name");              node1.InnerText = name;              root.AppendChild(node1);               XmlElement node2 = xmlDocument.CreateElement("Birth");              node2.InnerText = birth;              root.AppendChild(node2);               //獲取節(jié)點(diǎn)元素              string xmlStr2 = xmlDocument.OuterXml;               Response.Write(xmlStr2);              Response.End();           }      }  }

Xml格式前臺(tái)代碼：

<script src="../Scripts/jquery-1.8.0.js" type="text/javascript"></script>      <script type="text/javascript">          $(function () {              $("#btnXml").click(function () {                  $.ajax({                      url: "XmlData.aspx",                      type: "get",                      dataType: "xml",                      success: Success,                      error: function (result) {                          alert("相應(yīng)內(nèi)容非xml格式！");                      }                  });              });          });           function Success(xmlResult) {              //獲取返回結(jié)果              var result = xmlResult;              //找尋根節(jié)點(diǎn)并循環(huán)遍歷              $(result).find('root').each(function (key) {                  //獲取子節(jié)點(diǎn)名為Name的值                  var name = $(this).children("Name").text();                  //獲取子節(jié)點(diǎn)名為Birth的值                  var birth = $(this).children("Birth").text();                  $("#tbShow").val(name + ":" + birth);              });          }      </scri

實(shí)例四：ajax調(diào)用wcf獲取數(shù)據(jù)

首先貼上模塊圖：

首先定義好數(shù)據(jù)契約和操作契約，貼上StudentService.svc代碼：

StudentService.svc   namespace ajaxwcf   {       [ServiceContract(Namespace = "")]       [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]       public class StudentService       {           // 要使用 HTTP GET，請(qǐng)?zhí)砑?nbsp;[WebGet] 特性。(默認(rèn) ResponseFormat 為 WebMessageFormat.Json)           // 要?jiǎng)?chuàng)建返回 XML 的操作，           //     請(qǐng)?zhí)砑?nbsp;[WebGet(ResponseFormat=WebMessageFormat.Xml)]，           //     并在操作正文中包括以下行:           //         WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";           [OperationContract]           //獲取學(xué)生數(shù)據(jù)           public List<Student> GetStudents()           {               string sqlConn = ConfigurationManager.ConnectionStrings["SqlConn"].ConnectionString;               SqlConnection conn = new SqlConnection(sqlConn);               SqlDataAdapter da = new SqlDataAdapter("select * from AJAX_Tab", conn);               DataSet ds = new DataSet();               da.Fill(ds);               List<Student> Stulis = new List<Student>();               DataTable dt = ds.Tables[0];               Student student = null;               foreach (DataRow row in dt.Rows)               {                   student = new Student();                   student.Sname = row["sname"].ToString();                   student.Sage = row["sage"].ToString();                   student.Sadd = row["sadd"].ToString();                      Stulis.Add(student);               }                  return Stulis;           }       }          //數(shù)據(jù)契約       [DataContract]       public class Student       {           private string sname;              [DataMember]           public string Sname           {               get { return sname; }               set { sname = value; }           }           private string sage;              [DataMember]           public string Sage           {               get { return sage; }               set { sage = value; }           }           private string sadd;              [DataMember]           public string Sadd           {               get { return sadd; }               set { sadd = value; }           }       }   }

在web.config中進(jìn)行配置，上代碼：

好了，這樣wcf就配置好了，接下去就是頁(yè)面端的調(diào)用了，貼上ajax_wcf.aspx前臺(tái)頁(yè)面代碼：

<script type="text/javascript">         //載入WCF         function loadWCF() {            var student = new StudentService();              arr = student.GetStudents(succeededCallback, filedCallback);                  }         //成功         function succeededCallback(result, userContext, methodName) {             var arr = new Array();             arr = result;             //動(dòng)態(tài)創(chuàng)建表格信息 并賦值             var table = document.getElementById("ajaxTab");             for (var i = 0; i < arr.length; i++) {                 var tr = document.createElement("tr");                 var td1 = document.createElement("td");                 td1.innerHTML = arr[i].Sname;                  var td2 = document.createElement("td");                 td2.innerHTML = arr[i].Sage;                  var td3 = document.createElement("td");                 td3.innerHTML = arr[i].Sadd;                   tr.appendChild(td1);                 tr.appendChild(td2);                 tr.appendChild(td3);                  table.appendChild(tr);             }         }          //失敗         function filedCallback(error,userContext,methodName) {             alert("Error!");          }

這樣整個(gè)項(xiàng)目就完成了，接下去貼效果：

實(shí)例五[補(bǔ)充內(nèi)容]：Json格式數(shù)據(jù)的打包和解包方式

在打包和解包中，我們?nèi)耘f用到了上面提及的Json數(shù)據(jù)API，同樣要先添加引用，由于代碼都有了對(duì)應(yīng)的注釋?zhuān)辉俣嘧鑫淖值馁樖觯苯淤N上代碼和效果吧：
