How to include a variable in a function - Javascript

Question

Ok, so I have a variable that contains some information that needs to go in a function. For example, if I have;

var apikey="123456789";

function foo() {
    $.getJSON('http://api.websiteexample.com/ + apikey');
}

I'm looking to add some information that is stored in a variable to the end of a website address when requestion JSON data.

Is there way I've done in the example correct?

Thanks!

Try like below,

//Note the quotes moved -----------------v
$.getJSON('http://api.websiteexample.com/' + apikey);

When you have it inside quotes.. It would be considered as a string. You need to put it outside quotes for it to know it is an variable.

Is it possible to add another string after? So after apikey, I could continue the URL?

@user1658756 Yes, just append with + operator

Okay so it'd be $.getJSON('http://api.websiteexample.com/' + apikey + 'foo');. That'll appear as api.websiteexample.com/123456789foo, right?

Try it this way

var apikey="123456789";

function foo(key) {
    $.getJSON('http://api.websiteexample.com/ ' + key);
}

foo(apikey);

So you can pass the apikey as a parameter to the function. It can be called anything you want. It allows your function to be resuable because it will work the same way if your api key changes.
