如何找到挂断我的AJAX电话的内容并进行修复？
几天前，一个工作正常的AJAX电话突然挂在我的网站上。我不知道如何再追踪这个问题了。因为这个网站是在WordPress上，我想也许4.2.2更新搞砸了。但我又回到了旧版本，但没有修复它。
XHR：
发生了什么？当我单击一个菜单项时，它会对admin-ajax.php进行AJAX调用，然后在没有客户端活动的情况下挂起大约30秒，直到其他请求完成。我想，挂机发生在服务器上，但我不确定如何证明这一点。
这里是我的AJAX调用函数：
function loadAjax(id, pageOrder) {
ajaxCalled = true;
jQuery('.side-menu').fadeIn(200, function () {
jQuery(this).find('li.current-menu-item').removeClass('current-menu-item');
jQuery(this).find('li').eq(parseInt(pageOrder)).addClass('current-menu-item');
});
jQuery.post(
ajaxurl, // link to wp-ajax.php usually generated within a theme, if not, create manually
{
action: 'get_subpages', // Action in functions.php ajax function
id: id // parameter sent
},
function (response) {
//////console.log('response received');
if (response !== "0") {
setTimeout(function () {
jQuery('.ajax-loader').removeClass('loading');
jQuery('.ajax-loader').addClass('loaded');
}, 1500);
jQuery(".ajax-content").html(response);
defaultPageSetFigureHeight(windowHeight);
featureSidebar();
pullSubpages();
var title = jQuery('.ajax-content .content').attr('data-title');
jQuery('.logo .page').html(title);
}
});
jQuery(window).unbind('touchend touchstart wheel DOMMouseScroll mousewheel keyup').unbind(handlers);
}
function updateURL(urlPath) {
history.pushState('data', '', urlPath);
}
function detectEndScroll() {
jQuery(window).scroll(jQuery.debounce(200, function () {
scrollDetected = parseInt(scrollTop / windowHeight); // This needed to balance on scrolling
//alert(scrollTop);
if (scrollAction === 'scroll') {
var isiPad = navigator.userAgent.match(/iPad/i) != null;
if (!isiPad) {
postionPages(); // Do not remove. Bug fix
}
}
}));
}
function postionPages() {
if (!isMobile()) {
scrollAction === 'disable';
scrollTopBeforeScrolling = scrollDetected * windowHeight;
//console.log("CURRENT: " + scrollTop + " BEFORE: " + scrollTopBeforeScrolling);
if (scrollTop > scrollTopBeforeScrolling) {
direction = 'down';
} else {
direction = 'up';
}
var module = scrollTop % windowHeight;
var diff = module / windowHeight;
if (diff > 0.15 && direction === 'down') {
scrollDetected++;
}
if (diff > 0.75 && direction === 'up') {
scrollDetected--;
}
//console.log("MODULE " + module + " scrollTop: " + scrollTop + " windowHeight: " + windowHeight + " Scroll: " + scrollDetected + ' DIRECTION: ' + direction);
if (scrollTop % windowHeight !== 0) {
if (!ajaxCalled) {
var skip = scrollDetected * parseInt(windowHeight);
animateFastScrolling(skip);
}
}
}
}
以下是get_subpages中调用的functions.php操作：
add_action("wp_ajax_get_subpages", "get_subpages");
add_action("wp_ajax_nopriv_get_subpages", "get_subpages");
function get_subpages() {
$id = $_POST['id'];
$post = get_post($id);
$pageContent = $post->post_content;
$pageTitle = $post->post_title;
$subpageOpen = get_post_meta($id, "mbe_subpage_open", 1);
?>

array_push($subpageArray, $subpageIDstring);
}
$parameters = implode(',', $subpageArray);
global $wpdb;
$subpagesResults = $wpdb->get_results("SELECT * FROM `wp_posts` WHERE `ID` IN (" . $parameters . ") AND `post_type` LIKE 'page' ORDER BY `wp_posts`.`menu_order` DESC");
createMapPopups();
foreach ($subpagesResults as $subpage) {
$subpageID = $subpage->ID;
$isHero = get_post_meta($subpageID, 'mbe_hero', 1);
$isMap = get_post_meta($subpageID, 'mbe_map', 1);
$blueMapType = get_post_meta($subpageID, 'mbe_map_blue_type', 0);
$slug = $subpage->post_name;

这可能是由内存泄漏造成的吗？如果是这样，我很难跟踪它。或者这是在PHP的某个地方发生的？
这可能是显而易见的，但我承认，我不太清楚自己在做什么。我最初自己并没有编写所有这些代码，但我现在负责该网站。让我知道，如果有更多信息，我可以为您提供所有信息。感谢。
UPDATE 6/12/15：我们发现当我们将WordPress版本还原为4.1.5时，AJAX过程正常工作 - 这必定意味着最近的一个WordPress更新打破了它，是吗？
