If you're on Windows create a localhost site in IIS[0], then test your queries against that. You may have to enable the IIS feature in the control panel first[1].

Alternatively, if you're using a decent IDE it will provide similar functionality.

Easy enough on a Mac which comes with the necessary software already
installed. Database is not relevant. You use your own machine as the
server.

That depends on what you mean by local.

If you meant to run it from local web server using http:// or https://, then
yes you can.

If you meant to run it directly from the file system using file://, then no.
Most web browsers don't allow the file: protool to be used with AJAX (at
least by default). I don't know about Node.js, though.

You can create json or xml documents and request them with ajax requests.
But you'll need a server, because ajax talks to a server.

What you don't need for ajax is a database.

While the x in Ajax stand for xml,
any file can be requested and streamed,
as long as browser security restrictions are not compromised.

var xmlhttp = new XMLHttpRequest();
xmlhttp.open('GET', 'justafile.txt', true);
xmlhttp.send();

Json and xml are just ways such files can be structured.

Indeed, also no swimming pools.

No you don't. What you are requesting is *data*, which can be in any
format as long as the two sides agree on what the format is.

Both correct. The server can be local.

Yes he can. OP can do other things as well, but OP _CAN_ do as I
suggested for the purposes of testing javascript / jquery ajax.

I didn't say that was the only thing he could do.

Technically you're just requesting a response, which may or may not
include a body, but unless you want to write your own parser to convert
the body you're sending from your server into data for your javascript to
use on the client, json and xml tend to be the two formats that javascript
can process natively.

Having said that, you can eg send a b64 encoded jpg image and:

document.getElementById(img_id).attr("src", "data:image/jpg;base64," +
data);

This may well work for other media types such as music files, but richard
should note well that I have no intention of helping him with any such
project!
