jQuery Ajax 调用Aspx.Net WebService

我在这里将jQuery Ajax 调用Aspx.Net WebService 的几个常用的方法做了一个整理,提供给正在找这方面内容的博友,希望能给学习jQuery的朋友一点帮助,可以直接复制代码运行。

JQuery 中的Ajax调用WebServices 的总结 收藏
使用JQuery中javascript:;" onClick="javascript:tagshow(event, 'ajax');" target="_self">ajax方法访问web服务。

1.ajax方法需要填写:
 

JScript. code
$.ajax({type:"POST",//注明 返回JsoncontentType:"application/json;utf-8",//CollegeDepartWebServices.asmx web服务名 /GetCollegeDepart 方法名http://www.cnblogs.com/tangself/admin/%22CollegeDepartWebServices.asmx/GetCollegeDepart%22,//strDepartId 参数名称 collegeId 参数值data:"{strDepartId:"+collegeId+"}",dataType:"json",success:function(result){varjson=nulltry{if(result){//因为返回的是ArrayList 所以循环取出其中的值$.each(result,function(i, n){//ddlDepart 为下来菜单。循环的向下拉菜单中添加新的选项ddlDepart.options[ddlDepart.length]=newOption(n.CollegeDepartTitle,n.CollegeDepartId);});}}catch(e){alert("错误>>"+e.message);return;}},error:function(data){alert(data.status+">>>"+data.statusText);}});

----
CollegeDepartWebServices.asmx.cs web服务类

C# code
[WebService(Namespace="http://tempuri.org/%22)][WebServiceBinding(ConformsTo=WsiProfiles.BasicProfile1_1)][ScriptService]publicclassCollegeDepartWebServices : System.Web.Services.WebService{publicCollegeDepartWebServices(){//如果使用设计的组件,请取消注释以下行//InitializeComponent();}[WebMethod][System.Xml.Serialization.XmlInclude(typeof(CollegeDepartInfo))]publicArrayList  GetCollegeDepart(stringstrDepartId){CollegeDepartBL.FlushCollegeDepartCache();if(string.IsNullOrEmpty(strDepartId))returnnull;ArrayList myList=CollegeDepartBL.GetCollegeDepartListByCollegeID(int.Parse(strDepartId));returnmyList;}}

说明:
ArrayList 中 存为对象CollegeDepartInfo
其属性为:stirng CollegeDepartTitle 和 int CollegeDepartId
在javascript中
ddlDepart.options[ddlDepart.length]=new Option(n.CollegeDepartTitle,n.CollegeDepartId);

Option的参数就是依据他们的。

最后重要的是:
类上方添加的
[ScriptService]
必须添加,否则ajax无法调用WebService

$.ajax(properties)
使用HTTP请求(XMLHttpRequest)载入一个远程页面。 这是jQuery的低级AJAX实现。要查看高级抽象,见$.set、$.post等。 $.ajax()返回创建好的XMLHttpRequest对象。多数情况下并不需要直接操纵这个对象,但是如果需要手动中止请求,它也是可用的。 注意:要确保服务器返回正确的MIME类型(例如:XML是“text/xml”)。如果返回了错误的MIME类型就会导致jQuery无法处理的严重问题。

支持的数据类型包括(见dataType选项):

 "xml": 返回一个可以由jQuery对象处理的XML文档。

"html": 返回纯文本格式的HTML,包括求值后的脚本标记。

"script": 将响应作为Javascript语句求值,并返回纯文本。

"json": 将响应作为JSON求值,并返回一个Javascript对象。

$.ajax()带有一个参数--“名/值对”形式的一个对象,用于初始化和处理请求。

以下就是可用的所有“名/值对”:

(String) url - 要将请求发送到的URL地址。

(String) type - 请求的类型 ("POST" 或 "GET"), 默认是 "GET"。

(String) dataType - 期望从服务器端返回的数据类型。无默认值:如果服务器返回XML,就将responseXML传递到回调函数,否则将resposeText传递到回调函数。

 (Boolean) ifModified - 只有响应自上次请求后被修改过才承认是成功的请求。是通过检查头部的Last-Modified值实现的。默认值为false,即忽略

对部分的检查 (Number) timeout - 覆盖全局延迟的局部延迟,例如,在其他所有延迟经过1秒钟后,启动一个较长延迟的单独请求。有关全局延迟,见$.ajaxTimeout()。

 (Boolean) global - 是否为当前的请求触发全局AJAX事件处理函数,默认值为true。设置为false可以防止触发像ajaxStart或ajaxStop这样的全局事件处理函数。

 (Function) error - 当请求失败时调用的函数。这个函数会得到三个参数:XMLHttpRequest对象、一个描述所发生的错误类型的字符串和一个可选异常对象(如果有)。

 (Function) success - 当请求成功时调用的函数。这个函数会得到一个参数:从服务器返回的数据(根据“dataType”进行了格式化)。 (Function) complete - 当请求完成时调用的函数。这个函数会得到两个参数:XMLHttpRequest对象和一个描述请求成功的类型的字符串。

 (Object|String) data - 要发送到服务器的数据。如果还不是一个字符串,就自动轮换为一个查询字符串。即附加到GET请求的url后面的字符串。要防止自动处理见processData选项。

 (String) contentType - 设置发送请求的content=type。默认值是 "application/x-www-form-urlencoded", 这个值能满足多数情况。

 (Boolean) processData - 在默认的情况下,如果data选项传进的数据是一个对象而不是字符串,将会自动地被处理和转换成一个查询字符串,以适应默认的content-type--"application/x-www-form-urlencoded"。如果想发送DOMDocuments,就要把这个选项设置为false。

 (Boolean) async - 在默认的情况下,所有请求都是以异步的方式发送的(值为true)。如果要使用同步方式,需要将此项设置为false。 (Function) beforeSend - 用于设置自定义头部等信息的预调用函数,接收一个唯一的参数--XMLHttpRequest对象。

Load a remote page using an HTTP request. This is jQuery's low-level AJAX implementation. See $.get, $.post etc. for higher-level abstractions. $.ajax() returns the XMLHttpRequest that it creates. In most cases you won't need that object to manipulate directly, but it is available if you need to abort the request manually. Note: Make sure the server sends the right mimetype (eg. xml as "text/xml"). Sending the wrong mimetype will get you into serious trouble that jQuery can't solve. Supported datatypes are (see dataType option): "xml": Returns a XML document that can be processed via jQuery. "html": Returns HTML as plain text, included script tags are evaluated. "script": Evaluates the response as Javascript and returns it as plain text. "json": Evaluates the response as JSON and returns a Javascript Object $.ajax() takes one argument, an object of key/value pairs, that are used to initalize and handle the request. These are all the key/values that can be used: (String) url - The URL to request. (String) type - The type of request to make ("POST" or "GET"), default is "GET". (String) dataType - The type of data that you're expecting back from the server. No default: If the server sends xml, the responseXML, otherwise the responseText is passed to the success callback. (Boolean) ifModified - Allow the request to be successful only if the response has changed since the last request. This is done by checking the Last-Modified header. Default value is false, ignoring the header. (Number) timeout - Local timeout to override global timeout, eg. to give a single request a longer timeout while all others timeout after 1 second. See $.ajaxTimeout() for global timeouts. (Boolean) global - Whether to trigger global AJAX event handlers for this request, default is true. Set to false to prevent that global handlers like ajaxStart or ajaxStop are triggered. (Function) error - A function to be called if the request fails. The function gets passed tree arguments: The XMLHttpRequest object, a string describing the type of error that occurred and an optional exception object, if one occured. (Function) success - A function to be called if the request succeeds. The function gets passed one argument: The data returned from the server, formatted according to the 'dataType' parameter. (Function) complete - A function to be called when the request finishes. The function gets passed two arguments: The XMLHttpRequest object and a string describing the type of success of the request. (Object|String) data - Data to be sent to the server. Converted to a query string, if not already a string. Is appended to the url for GET-requests. See processData option to prevent this automatic processing. (String) contentType - When sending data to the server, use this content-type. Default is "application/x-www-form-urlencoded", which is fine for most cases. (Boolean) processData - By default, data passed in to the data option as an object other as string will be processed and transformed into a query string, fitting to the default content-type "application/x-www-form-urlencoded". If you want to send DOMDocuments, set this option to false. (Boolean) async - By default, all requests are send asynchronous (set to true). If you need synchronous requests, set this option to false. (Function) beforeSend - A pre-callback to set custom headers etc., the XMLHttpRequest is passed as the only argument.

返回值
XMLHttpRequest

参数
properties (Map): Key/value pairs to initialize the request with.
示例
说明:
载入并执行一个JavaScript文件。

jQuery 代码:
$.ajax({ type: "GET", url: "test.js", dataType: "script" })
 
--------------------------------------------------------------------------------

说明:
将数据保存到服务器,并在保存完成后通报用户。

jQuery 代码:
$.ajax({ type: "POST", url: "some.php", data: "name=John&location=Boston", success: function(msg){ alert( "Data Saved: " + msg ); } });
 
--------------------------------------------------------------------------------

说明:
同步载入数据。当请求处于活动期间阻塞浏览器。如果必须同步载入数据,最好是通过其他手段来阻止用户的交互,而不是阻塞整个浏览器。

jQuery 代码:
var html = $.ajax({ url: "some.php", async: false }).responseText;
 
--------------------------------------------------------------------------------

说明:
将一个XML文档作为数据发送到服务器。通过将processData选项设置为false,可以避免把自动把数据转换为字符串。

jQuery 代码:
var xmlDocument = [create xml document]; $.ajax({ url: "page.php", processData: false, data: xmlDocument, success: handleResponse });
