How to restructure object to array of objects?

Question

I have this object

var data = {
         _id : 131233442543,
         SocialMedia_0__Name_: "facebook",
         SocialMedia_0__URL_: "http://facebook.com/test",
         SocialMedia_1__Name_: "twitter",
         SocialMedia_1__URL_: "http://twitter.com/test",
         SocialMedia_1398083781749__Name_: "linkedin",
         SocialMedia_1398083781749__URL_: "http://linkedin.com/test"
        };

And I need to restructure the object to be like this:

justSites = [
{
name : "facebook",
url : "http://facebook.com/test"
},
{
name : "twitter",
url : "http://twitter.com/test"
},
{
name : "linkedin",
url : "http://linkedin.com/test"
}
];

This indexes in names (0, 1, 1398083781749) are serial, with no holes? — Tommi

You need to parse it, loop, then push into a new object and encode it to json, what language are you using? — Yazan Malkawi

Does the array need to be in the same order as the property "indices"? — Bergi

Please note that this has nothing to do with JSON, at all. What you have is a JavaScript object and you seem to want to restructure it into an array of objects. — Felix Kling

This should do it:

var justSites = [], m;
for (var p in data)
    if (m = p.match(/SocialMedia_(\d+)__Name_/))
        justSites.push({
            name: data[p],
            url: data["SocialMedia_"+m[1]+"__URL_"]
        });
