In other words, say I have an index.html file.

In that index.html file, I have a <script> section that does stuff.

In the same directory as index.html, I have someStuff.json (which is a JSON file).

In that script section, I want to do something like this:

<script>

...
var newVariable = someStuff.json;
...

</script>

and now that newVariable contains unparsed JSON, where I can there on do stuff like

var otherNewVariable = JSON.parse(newVariable);

Does that make sense?

You can do something like this:

Code

function readJSON(file) {
var request = new XMLHttpRequest();
request.open('GET', file, false);
request.send(null);
if (request.status == 200)
return request.responseText;
};

var myObject = JSON.parse(readJSON('/local/path/to/json'));

Oh, that looks viable.

so if my file's name was employees.json, then it would be:

JSON.parse(readJSON('employees.json'));?

I'm trying it out and it's being weird.

EDIT: got it, was missing a bracket in my json file.

THANKS!

if it is in the same directory, yes just 'employees.json'

No problem, glad I could help!

ajax equivalent which is nice for async calls:

Code

$.ajax({
url: '/employees.json',
type: "GET",
dataType: "json",
success: function (data) {
alert(data.responseText);
}
});
