Jquery访问Webservice Chrome异常

Jquery访问Webservice Chrome浏览器报
（ XMLHttpRequest cannot load "XXX". No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin "XXX" is therefore not allowed access. ）
异常解决方案，Webservice增加system.webserver配置节
web.config 配置如下：
<configuration>
  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>
</configuration>
