javascript - 如何在 jQuery Ajax Success 返回的数组中循环？

Question

我试图循环从 PHP 返回的数组。但是还是不明白。例子是~

PHP:

$items = array();
$items["country"] = "North Korea",
$items["fruits"] = array(
                      "apple"=>1.0,
                      "banana"=>1.2,
                      "cranberry"=>2.0,
                    );
echo json_encode( $fruits );

jQuery:

$.ajax({
    url: "items.php",
    async: false,
    type: "POST",
    dataType: "JSON",
    data: { "command" : "getItems" }
}).success(function( response ) {

    alert( response.fruits.apple ); //OK
    // <------ here, how do i loop the response.fruits ? -----

});

请问我怎样才能循环知道我得到了哪些水果？

你可以这样做:

$.each(response.fruits,function(key,value){

console.log(key+":"+value);

});
