With this code I want to parse this JSON: 
使用此代码，我想解析此JSON：
asd'cp'pd'pcd'sp'sdp'dc asd'cp'pd'pcd'sp'sdp'dc
The browser console give me this error (I don't understand what it means): 浏览器控制台给我这个错误（我不明白这意味着什么）：
XMLHttpRequest cannot load http://sath3g.altervista.org/index.php?get_param=value. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
What is wrong? 怎么了？

I think your are trying to do a cross domain ajax request.Browser will block the request because of Access-Control-Allow-Origin . 我认为您正在尝试执行跨域ajax请求。由于Access-Control-Allow-Origin将阻止请求。
If you need to access the data from another domain i'll suggest you to use jsonp . 如果您需要访问其他域中的数据，我建议您使用jsonp 。 But for that, the required server should bind the return data with a client side function. 但为此，所需的服务器应该将返回数据与客户端功能绑定。
Also you can try enabling cors in the ajax request. 您也可以尝试在ajax请求中启用cors 。
