访问.net问题，能查询，不能保存

XMLHttpRequest cannot load http://localhost:2080/baas/PigManager/Pig_action/saveJxDw. No 'Access-Control-Allow-Origin' header is present on the requested resource.

http://localhost:8080/x5/UI2/v_/PigManager/mainActivity.w?device=m
动态配置访问baas的路径：justep.Baas.BASE_URL = "http://localhost:2080/baas";

能查询出数据，但不能保存，麻烦明白的再给指点指点，考虑了半天，解决不了！！！！！

是跨域问题！BaasServer的端口和 访问.w页面的端口不一致 就会参数跨域
请设置BaasServer 支持跨域请求

response.setHeader(“Access-Control-Allow-Origin”, “*”);

跨域的解决方法请参考：
