我從我的 PHP 代碼和查詢中得到了我需要的東西；除了我真的很難將數(shù)據(jù)帶到前端以填充 HTML 下拉列表。這是我在 PHP 方面的內(nèi)容；一切正常$app->get('/dlteopt', function ($request, $response, $args) {               $which = $_GET['id'];    if ($which) {        if ($which == 'table_1'){            $sql = "SELECT item1 FROM daya.blahblah";        } else if ($which == 'table_2'){            $sql = "SELECT item2 FROM daya.blahblah2";        } else if ($which == 'table_3'){            $sql = "SELECT item3 FROM daya.blahblah3";         }        $stid = oci_parse($this->db, $sql);                $list = array();        while ($list = oci_fetch_array($stid, OCI_ASSOC)) {            $list[] = $list;            var_dump($list); // this outputs the correct array I need, but cant bring it to front correctly into dropdown        }        if (!@oci_execute($stid)) {            $error = oci_error($stid);            throw new Exception($error['message']);        }         oci_execute($stid);    }這是 jQuery；控制臺(tái)response日志只是which我隨get請(qǐng)求發(fā)送的標(biāo)志 ( ) 變量，它確定通過用戶場景查詢哪個(gè)表。我需要的數(shù)組被省略了...... let which = $(frm).attr("id");    $.get('dlteopt', {id: which }, function (response) {        console.log(response); // this just consoles as the $which var no array       $.each(response, function(index, value) {         // started logic to append values in option; but no array or obj found/brought in to iterate through, can handle this part if can get array       });    });html下拉；只是帶有占位符的標(biāo)準(zhǔn) HTML 選擇，直到填充：<select name='agent' id='agent'><option>Loading...</option></select>我在這里做錯(cuò)了什么？或丟失/遺忘？
