PS：一些测试页面偶尔会加载本地的json文件，没有开web server一般不能访问…不一定每次都要开nginx或apache解决, chrome可以加启动参数“allow-file-access-from-files”
Using –disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using –allow-file-access-from-files switch?
Before using these commands be sure to end all running instances of Chrome.
On Windows:
chrome.exe –allow-file-access-from-files
On Mac:
open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files
