私は明確に定義されたAJAXフィルターを2つの部分で、1つは[もっと読み込む]ボタン用、もう1つはドロップダウンフィルターの選択用です。両方とも、フロントエンドのプロパティのリストをリロードします。 AJAXと連携して動作します(たとえば、ドロップダウンで最小価格、最大価格、ベッド数を選択すると、リストが更新され、[もっと読み込む]ボタンが正常に機能します)。
同じフィルターがURLパラメーターでも機能します。たとえば、URLが次の場合は、
mydomain.com/?min_price=100000&max_price=5000000&beds=3&page=3
これらのパラメーターでフィルターします。 3ページ分のプロパティも表示されます。これは、初期ロードを含め、うまく機能します。ただし、URLが直接読み込まれる場合、ページネーションでは機能しません。上記のURLをブラウザーに直接入力してロードすると、最初の結果は正しいですが、[さらに読み込む]ボタンをクリックすると、page = 3がpage = 4(正しい)に変わりますが、フィルターされていない完了したプロパティの2ページ目が追加されます、そしてそうし続けます-フィルタリングされたページネーションを続けるのではなく。
何が悪いのですか?
これが私のコードです(申し訳ありませんがたくさんあります!)

結局、自分で解決しました。私が行った方法は、loadmore AJAXが実行される前に、これらの行に沿って何かをURLパラメータを変数に渡すことでした
var url_string = window.location;
var price_min = (new URL(url_string)).searchParams.get("price_min");
var price_max = (new URL(url_string)).searchParams.get("price_max");
var bedrooms = (new URL(url_string)).searchParams.get("beds");
var property_type = (new URL(url_string)).searchParams.get("type");
var sort_by = (new URL(url_string)).searchParams.get("sort_by");
var the_page = (new URL(url_string)).searchParams.get("page");
次に、[もっと読み込む]ボタンをクリックすると、ajax呼び出しでREQUESTが機能するようになりました。
[〜#〜] post [〜#〜]をAJAXで送信but PHPで$ _ GET [ 'ページ']
if (!empty($_GET['page'])) {
$the_page = $_GET['page'];
}
$ _ REQUESTを使用できます
