Cross-origin request for local file

问题

I need to open a local html file in the browser. The javascript works fine but ajax stops working and XMLHttpRequest gives a cross origin error. Is there a way to run ajax from local directory. It is necessary for me that it is run from local file only.

Thanks

For anyone who wants to know, I had to run a server in the app to serve the js files. Seems like it's not possible to do it without running a server. If anyone knows of another way, do tell.

If you are using chrome, try this extension

CORS allows web applications on one domain to make cross domain AJAX requests to another domain. It's dead simple to enable, only requiring a single response header to be sent by the server.

What this extension does is add to response header rule - Access-Control-Allow-Origin: *

You can do that manually also by sending a response header.

For simple CORS requests, the server only needs to add the following header to its response: Access-Control-Allow-Origin: *
