您無法訪問不在您域中的內(nèi)容，除非它是返回 XML 或 JSONP 的 Web 服務(wù)
this is what I am trying to do.
I have made a few .html pages with JavaScript code in it and hosted them on a Yahoo server.
Now when a client with a certain browser views these web pages, the JavaScript code uses XMLHTTPRequest to make a connection at h1ttp://localhost:8080/myservlet/servlet1 to read some data.
I know, I want to connect to the web server running on the client's computer if the client has one i.e. I am using localhost in my xmlHTTPRequest.
But this is not working even when a client has a web server running on port 8080. On the client's computer I can access http://localhost:8080/mysevlet/servlet1 and the servlet is running fine, but through the .html page hosted on Yahoo server it does not work.
Anything that I am doing wrong here?
