Send php array to jquery ajax and create each loop from this array

Question

Hi, I actually read a lot of topics about array and jquery, and they all show an example using jquery inside the hmtl script tag, but I'm trying to learn how to read the array sent by php throught ajax inside the js file

here is my php example

$record = array('jazz','rock', 'punk', 'soft', 'metal');
echo json_encode($record);

then here is my ajax

$.ajax({
    url: "system/music_list.php",
    dataType: 'json',
    cache: false,
    success: function(response){
        // here i want to read the array and make a loop for each element 
    },
});

thanks if you can help me

Answer 1

try the baseline for a loop counting using length . This ... this should help.

 function ajax_test()
 {
    $.ajax({
        url: "system/music_list.php",
        dataType: 'json',
        cache: false,
        success: function(response)
        {
             for (var i = 0; i < response.length; i++)
             {
                 alert(response[i]);
             }
        }
    });
 }
