几天以来，我试图为我的问题找到解决方案：在@Oliver 的帮助下，我得到了 AJAX 工作。这是我获取数据并返回 JSON 的 PHP 代码：
if (isset($_GET['nexans'])) {
$nexans = json_decode($_GET['nexans'], true);
$tab_req = array();
foreach($nexans as $key => $value) {
$req_jsonmultipdf = $maPdoFonction - > PDF_Multi($key, $value, $_SESSION['ssetablissement_id'], '4', 'NEXANS');
$tab_req[] = $req_jsonmultipdf - > fetchAll(PDO::FETCH_ASSOC);
}
$retour = array(
"success" => true,
"data" => $tab_req
);
header('Content-Type: application/json; charset=utf-8');
echo json_encode($tab_req);
}
在这里，没问题。我需要使用 jsPDF 来生成 PDF 文件。我也需要 autoTable（如果您不知道，请使用 jsPDF 插件）。在这个 PDF 文件中，我必须在带有 autoTable 的表中插入 JSON 数据。
编辑：这是我生成PDF 文件的 JS ：
$.ajax({
type: "GET",
url: "../modules/ajax/A.php",
data: {
'A': _json
},
dataType: 'json',
success: function(json) {
var len = json.length;
if (len > 0) {
// Default export is a4 paper, portrait, using milimeters for units
var pdf = new jsPDF();
pdf.page = 1;

所以，从我的 AJAX 请求中，我得到一个数组，在这个数组中，每一行都是一个数组。我搜索一个解析我的 JSON 的解决方案，并填充 autoTable 以创建一个表，所以请。如果你有帮助我的想法，请。感谢您的回答。
