How to get a comma separated list from a JSON response?

Hello I have a javascript question whereby I am getting a JSON result:

{"0":"San Diego acls","1":"San Diego pals","2":" San Diego CPR","3":" Temecula acls","4":" Temecula pals"}

which is stored in a variable called data.

I want to parse this data variable and make a list like:

San Diego acls, San Diego pals, San Diego CPR, Temecula acls, Temecula pals

Any elegant ways?

Thanks

What you need is this:

var res = [];
for (var x  in obj)
    if (obj.hasOwnProperty(x))
        res.push(obj[x]);
console.log(res.join(","));

And there's one more way of 'elegantly' doing it (taken from Alex's answer),

res = [];
Object.keys(obj).forEach(function(key) {
    res.push(obj[key]);
});
console.log(res.join(","));

In case you need the result in that specific order, sorting the keys (that come from Object.keys(obj)) before invoking forEach on the array will help. Something like this:

Object.keys(obj).sort().forEach(function(key) {

This one also works.

$(document).ready(function(){
    var data = {"0":"San Diego acls","1":"San Diego pals","2":" San Diego CPR","3":" Temecula acls","4":" Temecula pals"};
    var csv = $.map(data,function(data){ return data;});
    alert(csv);
});

This is very simple in Javascript. You can access the variable data like this:

alert(data[0]);

which should alert "San Diego acls". Do the same for all of them using a loop. You can concatenate strings easily with the + operator.

var result = "";
for (var dString in data) { 
    result += dString + ", ";
}

This will create a string called result and add the elements of the strings in the array to it. It will also add ", " between each element as you described in the question.
