Question

PHP

Here is the code

<ul class="sj-flat-menu flyout-menu vertical fm-active" id="sj_flat_menu_17356473091448285129"><!--<![endif]-->
            <li class="fm-active  fm-first"><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/mezhdunarodnye-perevozki">Международные перевозки</a></div></div></li><li><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/strakhovanie">Страхование</a></div></div></li><li><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/temperaturnyj-rezhim-ot-20-s-do-20-s">Температурный режим от + 20 С  до -20 С</a></div></div></li><li><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/sertifitsirovannyj-registrator-rtr">Сертифицированный регистратор. Регистрация температурного режима</a></div></div></li><li><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/prodazha-diztopliva-so-skidkoj">Продажа дизтоплива со скидкой</a></div></div></li><li><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/sanitarnaya-obrabotka-avtomobilej">Санитарная обработка автомобилей</a></div></div></li><li class="fm-last"><div class="fm-item "><div class="fm-button"></div><div class="fm-link"><a href="/svoj-transport-foto">Свой транспорт (фото)</a></div></div>    </li>
</ul>

It is necessary that, for example, when you are on the "Insurance" page. The insurance menu item became inactive, that is, it could not be clicked on and would not follow the link, of course, to this very page.
Thanks for your help, in advance.!

Answer 1

$( document ).ready(function() {
    $('.fm-active a').attr('href', 'javascript:void()');
});

Answer 2

According to the idea above, the correct answer is written! But if we take into account that the parent Ul also has the .fm-active class, then it remains just to access it through li!

$('li.fm-active a').attr('href', 'javascript:void()');
