if know if target preceding sibling can use .prev().
description: preceding sibling of each element in set of matched elements. if selector provided, retrieves previous sibling if matches selector.
the .siblings() function work same way.
<div> <input name="codearticle" type="hidden" value="@code" class="codearticle" /> <input name="quantite" type="text" value="" class="quantite" /> </div> $(".quantite").on("change", function(e) { ... var selector = ".codearticle"; var codearticle = $(this).prev(selector).val(); }); since you've given input class can use filter selector.
