Save Json in Javascript variable

Question

I'm studying javascript these days and I have question. I have variable that contain an url. I would like to save the content of the url pointed by my variable in another variable...

The first variable is something like:

var Link = "http://mysite.com/json/public/search?q=variabile&k=&e=1";

If I open the link I see something like:

{

"count": 1,
"e": 1,
"k": null,
"privateresult": 0,
"q": "gabriel",
"start": 0,
"cards": [
    {
        "__guid__": "cdf8ee96538c3811a6a118c72365a9ec",
        "company": false,
        "__title__": "Gabriel Butoeru",
        "__class__": "entity",
        "services": false,
        "__own__": false,
        "vanity_urls": [
            "gabriel-butoeru"
        ]
    }
]
}

How can I save the json content in another javascript variable?

Answer 1

You would need a simple AJAX request to get the contents into a variable.

var xhReq = new XMLHttpRequest();
xhReq.open("GET", yourUrl, false);
xhReq.send(null);
var jsonObject = JSON.parse(xhReq.responseText);

Please note that AJAX is bound by same-origin-policy, in case that URL is different this will fail.
