File in Javascript

Question

I have a problem to get json. If I use: $.getJSON("file:///E:/WebProject/json/"+name+".json",resolve) It works!

But if I use: $.getJSON("/json/"+name+".json",resolve) It does not work. Why?

@Vohuman He's using Firefox, not Chrome, so that's fine, local Ajax requests are allowed. — blex

Look at the actual request sent to the server. Does the resource path correctly match what is expected/hosted? What is the response? — user2864740

@blex How do you know OP is using Firefox? The point wasn't Same-origin Policy. — Ram

@Vohuman Ok. Well, as you figured, Chrome and IE would block these requests, but not FF. And since his first call is working, I figured he was probably using FF, and that not having a server was not the issue. It's just the wrong path. — blex

Try Changing

 $.getJSON("/json/"+name+".json",resolve)

to

 $.getJSON("json/"+name+".json",resolve)

/json looks for the file in the root but I think json folder is in your web folder, not in the root.

When the first character is /, the browser fetch the file from the root of the site address

e.g.

file:///E:/WebProject + /json/name.json = file:///E:/json/name.json (maybe even without the E letter)

otherwise, the addition is relative:

file:///E:/WebProject + json/name.json = file:///E:/WebProject/json/name.json

as @Alp suggested, omit the first / and you should be fine
consider using a small local development server - if using python, cd to that folder and type python -m SimpleHTTPServer
