Codul jQuery este distribuit sub licen\u021ba MIT.       <\/p>\n<p> Lansarea jQuery 4.0 con\u021bine modific\u0103ri ce afecteaz\u0103 compatibilitatea invers\u0103, dar, conform dezvoltatorilor, majoritatea utilizatorilor vor putea trece f\u0103r\u0103 probleme la noua versiune cu modific\u0103ri minime \u00een codul lor. Pentru a simplifica migrarea, se poate utiliza un plugin special. Problemele de compatibilitate invers\u0103 sunt legate de eliminarea codului \u00eenvechit, de \u0219tergerea unor parametri interni nedocumenta\u021bi, de \u00eencetarea suportului pentru unele comportamente excesiv de complicate \u0219i de eliminarea suportului pentru API-urile declarate ca fiind \u00eenvechite. Eliminarea API-urilor \u0219i browserelor \u00eenvechite a permis reducerea dimensiunii arhivei gzip cu biblioteca cu 3 KB (versiunea slim ocup\u0103 acum 19.5 KB, iar cea complet\u0103 \u2014 27.5 KB).       <\/p>\n<p>Printre modific\u0103ri:  <\/p>\n<ul>\n<li class=\"l\"> Suportul pentru browserul IE 10 \u0219i versiunile mai vechi a fost \u00eencheiat (suportul pentru IE 11 este p\u0103strat, dar va fi eliminat \u00een jQuery 5.0), precum \u0219i pentru alte browsere \u00eenvechite, precum Edge Legacy, Android Browser \u0219i Firefox p\u00e2n\u0103 la versiunea 115.\n<li class=\"l\"> A fost inclus suport pentru API-ul Trusted Types, dezvoltat pentru a proteja \u00eempotriva manipul\u0103rii DOM-ului, care conduce la scripting \u00eentre site-uri (DOM XSS), de exemplu, \u00een cazul unei prelucr\u0103ri incorecte a datelor primite de la utilizator \u00een blocuri eval() sau inser\u021bii &#171;.innerHTML&#187;, ceea ce poate duce la execu\u021bia codului JavaScript \u00een contextul unei pagini specifice. \u00cen metodele jQuery acum poate fi transmis cod HTML sub form\u0103 de obiecte TrustedHTML.\n<li class=\"l\"> Codul jQuery a fost actualizat pentru a utiliza modulele JavaScript ESM (ECMAScript Module) \u0219i poate fi livrat \u0219i importat ca un modul.\n<li class=\"l\"> Func\u021biile care au fost marcate anterior ca fiind \u00eenvechite au fost eliminate: jQuery.isArray, jQuery.parseJSON, jQuery.trim, jQuery.type, jQuery.now, jQuery.isNumeric, jQuery.isFunction, jQuery.isWindow, jQuery.camelCase, jQuery.nodeName, jQuery.cssNumber, jQuery.cssProps \u0219i jQuery.fx.interval. \u00cen locul acestor func\u021bii, se recomand\u0103 utilizarea func\u021biilor standard JavaScript: Array.isArray(), JSON.parse(), String.prototype.trim() \u0219i Date.now().\n<li class=\"l\"> Au fost eliminate metodele interne nedocumentate ale obiectului Array \u2014 push, sort \u0219i splice.\n<li class=\"l\"> Ordinea de procesare a evenimentelor de schimbare a focusului a fost adus\u0103 la conformitate cu specifica\u021bia W3C \u2014 blur, focusout, focus \u0219i focusin.\n<li class=\"l\"> Dimensiunea variantei reduse (slim), care nu con\u021bine module ajax \u0219i effects, a fost redus\u0103 la 19.5k datorit\u0103 \u00eentreruperii furniz\u0103rii obiectelor Deferred (se recomand\u0103 utilizarea Promises standard) \u0219i a Callbacks.  <\/ul>\n<p>Sursa: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64637\">opennet.ro<\/a>
