AJAX Get from file on the Computer

Question

I'm using JQuery: $.getJSON() to load a json data file on my computer.

I get the error:

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

How do I get around this problem.

Are you trying to load a file from your own computer? If so, JavaScript is not allowed to access your computer's file system for security reasons. — SparoHawk

it is from my own computer! so does this mean there is absolutely no way it can happen? — Callum Linington

@No1_Melman: The only way for JavaScript to read a file from your computer is if you use an <input type="file" /> and you select the file. There is no other way. Also, just FYI: AJAX only works with a web server. You can't AJAX to/from your local computer (file:///) — gen_Eric

Are you using 'file://'? If so, that isn't going to work since javascript can't just access a file on your computer. — Nick

I suggest you set up a WAMP server on your machine. Without a webserver, you cannot make AJAX calls. — gen_Eric

There is no way at the moment to get around this without using a web server.

Due to a security protocol.
