WebService项目配置文件
<system.web>
<!--提供Web服务访问方式-->
<webServices>
<protocols>
<add name="HttpSoap"/>
<add name="HttpPost"/>
<add name="HttpGet"/>
<add name="Documentation"/>
</protocols>
</webServices>
</system.web>
由于使用jquery.getJson的方式调用Web服务后，传递中文时会造成中文乱码问题:
所以在配置文件中应配置如下内容：
<system.web>
<!-- 设定传参乱码问题 -->
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8"/>
</system.web>
调用截图如下：
最后附上源码：JqCrossDomain.zip
