Question

I need to load a simple .CSV file from JS (That’s not the problem here), but the “script” need to be portable (i will use it as the screen on a competition), and score data will be inserted in the CSV, and JS will be updating it’s data based on the CSV.

But my problem here is: I need to run it without apache or a server, because i cant make shure the people who will use it, will have apache and also Internet… It need to be opened from a folder (Just a HTML with JS, and a file in the same folder with the .CSV)

When i try to access files from jQuery ($.get(..., ..., "jsonp"), and $.get()), Chrome output this error:

XMLHttpRequest cannot load file:PATHTOTHEFILE Origin null is not allowed by Access-Control-Allow-Origin.

This happens because the browser blocks it’s content (for security reasons).

How can i “deal” with this problem, or do you know a better solution, to save some simple data and read it from JS without secury problems?

Thanks

Answer 1

you need to add –allow-file-access-from-files to the chrome startup command line

make a BAT file and get you users to click that to start your app

%LOCALAPPDATA%\Google\Chrome\Application\chrome.exe ^
--allow-file-access-from-files ^

swap out the http:// for you file url.
