How to parse data from link that is using php json_encode

Question

I would like to parse data from a link, then put them into variables. I have tried

window.onload = function() {
    autoRefreshRadio();
};

function autoRefreshRadio(){
    var disabled = "Unavailable";
    var link = '{"url":"http://itspower.net/fullAPI.php"}';
    var obj = JSON.parse(link);
    alert(obj);
}

but it does not seem to alert anything. I'm quite new to Javascript so any help would be appreciated.

Answer 1

obj is a JS object. If you want the link string, you need to reference the property it's stored it, url :

function autoRefreshRadio(){
    var disabled = "Unavailable";
    var link = '{"url":"http://itspower.net/fullAPI.php"}';
    var obj = JSON.parse(link);
    alert(obj.url);
}

Although you're doing a lot of unnecessary legwork here. Just store the object in obj :

function autoRefreshRadio(){
    var disabled = "Unavailable";
    var obj = {"url":"http://itspower.net/fullAPI.php"}
    alert(obj.url);
}
