發(fā)現(xiàn)了有3種辦法可以解決這個(gè)問題，
1. 設(shè)置瀏覽器的options, enable access data sources across domains.
2. JSONP via jQuery. "JSON with padding" (JSONP)?
3. CORS: Http cross-origin resource sharing. ?set Access-Control-Allow-Origin to *
this is an extension to the standard XMLHttpRequest.
Internet Explorer 8 and 9 expose CORS via the XDomainRequest object, but have a full implementation in IE 10.? While Firefox 3.5 introduced support for cross-site XMLHttpRequests and Web Fonts, certain requests were limited until later versions. Specifically, Firefox 7 introduced the ability for cross-site HTTP requests for WebGL Textures, and Firefox 9 added support for Images drawn on a canvas using drawImage.
