Question

I have this function which helps me retrieve my friends ids, but i can’t seem to make it work for retrieving one friend’s id. I need to make a loop to get all friend ids.

Can you help me with this code?

function(response) {
    console.log(response);
    var testdiv = document.getElementById("test");
    testdiv.innerHTML = (
        response[0].uid2
    );
}

Answer 1

Just iterate over response :

for (i=0; i<=response.length; i++) {
   var uid2 = response[i].uid2;
   // do what you need to with uid2
}

And to demonstrate how you would use it

function(response) {
    console.log(response);
    var testdiv = document.getElementById("test");
    var newhtml = "";
    for (i=0; i<=response.length; i++) {
       newhtml += response[i].uid2;
    }
    testdiv.innerHTML = newhtml;
}
