js跨域调用wcf服务：
1.在Service.cs里添加：
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[JavascriptCallbackBehavior(UrlParameterName="jsoncallback")]
public class Service
{
[OperationContract]
[WebGet(RequestFormat = WebMessageFormat.Json)]
public string getChapter(string symbol,string chapter)
{
symbol="A";
chapter="BBBB";
string result=symbol+chapter;
}
}
2.在配置文件里：
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="webBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="navMetadataBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true" >
<baseAddressPrefixFilters>
<add prefix="string"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<services>
<service name="ReaderService" behaviorConfiguration="navMetadataBehavior">
<endpoint address="" behaviorConfiguration="webBehavior"
binding="webHttpBinding" contract="ReaderService" bindingConfiguration="webBinding" />
<!--<endpoint address="" binding="basicHttpBinding" contract="ReaderService" />-->
</service>
</services>
<bindings>
<webHttpBinding>
<binding name="webBinding" crossDomainScriptAccessEnabled="true"></binding> //跨域
</webHttpBinding>
</bindings>
</system.serviceModel>
3.在页面：
在文本框输入：两个文本框分别输入：A 和BBBB；
<script type="text/javascript">
function GetServerHelloWorldByJsop() {
var symbol = document.getElementById("symbol").value;
var chapter = document.getElementById("chapter").value;
$.getJSON("http://192.168.80.20:90/ReaderService.svc/getChapter?jsoncallback=?",
{ symbol: symbol, chapter: chapter },
function (data) {
alert(data);
});
}
</script>
<body>
<h2>修改订单</h2>
Code: <input type="text" id="symbol" />
Chapter: <input id="chapter" type="text" />
<input type="button" id="btnExcute" name="btnExcute" value="查询" onclick="GetServerHelloWorldByJsop();"/>
</body>
