CodeIgniter では、PHP でドロップダウンのネストされたような要素を作成するために、次の<select>関数を使用しています。
function list_categories(&$result, $cats, $sub = ''){ // <- THIS
foreach($cats as $cat){
//$cat['category']->id = $sub.$cat['category']->title;
$result[$cat['category']->id] = $sub.$cat['category']->title; // <- THIS
if( sizeof($cat['children']) > 0 ){
$sub2 = str_replace('—→ ', '–', $sub);
$sub2.= '–→ ';
list_categories($result, $cat['children'], $sub2); // <- THIS
}
}
}
// Make an array available outside the function
$categoryData = array(0 => '-- '.lang('FORM_SELECT_CATTOP').' --');
// Launch the function to fill out the array with nested sets
list_categories($categoryData, $categories);
HTML<select>リストを生成します：
jQueryで取得したJSONから同じことをしたいのですが、このjQuery関数を使用してJSONオブジェクトの最初のレベルよりも深くするための答えが見つかりません:
$.getJSON('../raw_get_categories/'+com_id_selected+'/0', function(data){
var items = [];
$.each(data, function(key, value, sub){
items.push('<option id="'+ key[0] + '">' + value[0] + '</option>');
});
console.log(items);
});
これは、PHP コードのように、同じ値を管理して取得したい JSON です。

誰かがforeachjQuery plsで同じステートメントを達成する適切な方法を提案できますか?
