尝试从url中获取JSON / JSONP数据并将结果显示在html网页上

When I enter the url for instance, "www.example.com" I get the return:

{
    shh: {
        id: 3730672,
        name: "Shh",
        profileIconId: 23,
        summonerLevel: 2,
        revisionDate: 1421646418000
    }
}

I am trying to get all this data and displaying it on my website that is HTML. I tried researching and even tried the following code,

$.getJSON('www.example.com', function(data){
    alert(data);
});

But it just displays nothing. Please help!
