jQuery loop through json?

Question

I have some json (var data)that looks like this:

{"success":"true","keywords":["firstkeyword","secondkeyword"]}

And im trying to loop through the keywords using this code:

            data.keywords.each(function(e){
                $('#campaign_keywords').append("<p>"+e+"</p>");
            });

But i get the error

Uncaught TypeError: Object firstkeyword,secondkeyword has no method 'each' 

Answer 1

You need to loop through it like this:

$.each(data.keywords, function (i, v) {
    $('#campaign_keywords').append("<p>"+data.keywords[i]+"</p>");
});

jQuery.each()

Answer 2

Its a javascript array, not jQuery object. just apply $ over it to make it jquery object like

    $(data.keywords).each(function(e){
        $('#campaign_keywords').append("<p>"+e+"</p>");
    });

Answer 3

That's because it's an array and it needs to be a jquery wrapped object in order to use jquery functions. Try:

$.each(data.keywords, function(index, value){...});
