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
