.getJSON（'https://172.16.25.47/JsonPTestApp/clurcService.asmx/getRCjson?SPA=8353/1000/0140' ，function（data）
{
alert（came inseide）
var test = data;
alert（test）;
}）;

.getJSON('https://172.16.25.47/JsonPTestApp/clurcService.asmx/getRCjson?SPA=8353/1000/0140', function (data) { alert("came inseide") var test = data; alert(test); });

当源与目标地址/主机名不匹配且服务器未指定允许此行为时，会导致CORS（跨源资源共享）问题。对此的简单解决方案是使服务器（这种情况下为asmx服务）返回允许您的原点的标头。如果您有一个域名，您可以指定此域名，否则您只需指定*通配符即可允许所有来源。



我还没有写asmx之前我认为解决方案可能如下：

CORS (Cross Origin Resource Sharing) issues are caused when the origin does not match the destination address / host name and the server has not specified that this behavior is allowed. The simple solution to this is to make the server (this case a asmx service) return the header that allows your origin. If you have a domain you are running this from you can specify this domain, otherwise you need only specify the * wildcard to allow all origins.

I haven't written asmx before however i think a solution could look like :

Response.AddHeader("Access-Control-Allow-Origin","*")
