jQuery je JavaScriptov\u00e1 knihovna, kter\u00e1 vych\u00e1z\u00ed z motto: Programov\u00e1n\u00ed v JavaScriptu by m\u011blo b\u00fdt p\u0159\u00edjemn\u00e9. jQuery se zam\u011b\u0159uje na \u010dast\u00e9, opakuj\u00edc\u00ed se \u00fakoly, odstra\u0148uje ve\u0161ker\u00e9 zbyte\u010dn\u00e9 zna\u010dkov\u00e1n\u00ed a \u010din\u00ed je kr\u00e1tk\u00fdmi, elegantn\u00edmi a srozumiteln\u00fdmi.<\/p><\/blockquote>\n

\njQuery m\u00e1 dv\u011b hlavn\u00ed v\u00fdhody. Prvn\u00ed je pohodln\u00e9 API pro manipulaci s webov\u00fdmi str\u00e1nkami. Zejm\u00e9na poskytuje siln\u00e9 metody pro v\u00fdb\u011br prvk\u016f.

\nPostupem \u010dasu se mechanismus v\u00fdb\u011bru p\u0159em\u011bnil na samostatnou knihovnu Sizzle<\/a><\/noindex>.<\/p>\n
Druhou v\u00fdhodou knihovny bylo to, \u017ee abstrahovala rozd\u00edly mezi prohl\u00ed\u017ee\u010di. V t\u011bch letech bylo obt\u00ed\u017en\u00e9 ps\u00e1t k\u00f3d, kter\u00fd by spolehliv\u011b fungoval ve v\u0161ech prohl\u00ed\u017ee\u010d\u00edch. <\/p>\n
Nedostatek standardizace znamenal, \u017ee v\u00fdvoj\u00e1\u0159i museli br\u00e1t v \u00favahu \u010detn\u00e9 rozd\u00edly mezi prohl\u00ed\u017ee\u010di a okrajov\u00e9 p\u0159\u00edpady. Pod\u00edvejte se na tenhle ran\u00fd zdrojov\u00fd k\u00f3d jQuery<\/a><\/noindex> a hledejte jQuery.browser. Tady je jeden z p\u0159\u00edklad\u016f:<\/p>\n

Pozd\u011bji jQuery usnadnila implementaci slo\u017eit\u011bj\u0161\u00edch technologi\u00ed, jako jsou animace a Ajax. Knihovna se de facto stala standardn\u00ed z\u00e1vislost\u00ed pro webov\u00e9 str\u00e1nky. A dnes zaji\u0161\u0165uje fungov\u00e1n\u00ed obrovsk\u00e9 \u010d\u00e1sti internetu.

Kontrola nad v\u00fdvojem jQuery se tak\u00e9 stala form\u00e1ln\u011bj\u0161\u00ed. V roce 2011 t\u00fdm vytvo\u0159il jQuery Board<\/a><\/noindex>. A v roce 2012 jQuery Board prom\u011bnila se v jQuery Foundation<\/a><\/noindex>.<\/p>\n
V roce 2015 se jQuery Foundation slou\u010dila s Dojo Foundation, aby vytvo\u0159ila JS Foundation<\/a><\/noindex>, kter\u00e1 se pot\u00e9 spojila s Node.js Foundation v 2019<\/a><\/noindex>-m za \u00fa\u010delem vytvo\u0159en\u00ed OpenJS Foundation<\/a><\/noindex>, v r\u00e1mci kter\u00e9ho byla jQuery jednou z «pr\u016fkopnick\u00fdch projekt\u016f<\/a><\/noindex>.»<\/p>\n

\nAv\u0161ak v posledn\u00edch letech jQuery ztratila na popularit\u011b<\/a><\/noindex>. GitHub odebral knihovnu z frontendu sv\u00e9ho webu<\/a><\/noindex>.

Nov\u00e9 frameworky<\/h3>\n
\nOd doby, kdy byl jQuery uveden, bylo vytvo\u0159eno mnoho framework\u016f, v\u010detn\u011b modern\u00edch l\u00eddr\u016f React<\/a><\/noindex>, Angular<\/a><\/noindex> a Vue<\/a><\/noindex>. Maj\u00ed dv\u011b d\u016fle\u017eit\u00e1 v\u00fdhody oproti jQuery.<\/p>\n
Za prv\u00e9, umo\u017e\u0148uj\u00ed snadno rozd\u011blit u\u017eivatelsk\u00e9 rozhran\u00ed na komponenty. Frameworky jsou navr\u017eeny tak, aby zpracov\u00e1valy vykreslov\u00e1n\u00ed a aktualizaci str\u00e1nky. A jQuery se obvykle pou\u017e\u00edv\u00e1 pouze k aktualizaci, zat\u00edmco server zaji\u0161\u0165uje dod\u00e1n\u00ed po\u010d\u00e1te\u010dn\u00ed str\u00e1nky.<\/p>\n
Na druhou stranu, komponenty React, Angular a Vue umo\u017e\u0148uj\u00ed \u00fazk\u00e9 propojen\u00ed HTML, k\u00f3du a dokonce i CSS. Stejn\u011b jako d\u011bl\u00edme k\u00f3dovou z\u00e1kladnu na mnoho sob\u011bsta\u010dn\u00fdch funkc\u00ed a t\u0159\u00edd, mo\u017enost rozd\u011blit rozhran\u00ed na znovu pou\u017eiteln\u00e9 komponenty usnad\u0148uje sestavov\u00e1n\u00ed a \u00fadr\u017ebu slo\u017eit\u00fdch web\u016f.<\/p>\n
Druhou v\u00fdhodou je, \u017ee nov\u011bj\u0161\u00ed frameworky dodr\u017euj\u00ed deklarativn\u00ed paradigmu, v r\u00e1mci kter\u00e9 v\u00fdvoj\u00e1\u0159 popisuje, jak by m\u011blo rozhran\u00ed vypadat, a proveden\u00ed v\u0161ech nezbytn\u00fdch zm\u011bn pro dosa\u017een\u00ed po\u017eadovan\u00e9ho p\u0159en\u00e1\u0161\u00ed na framework. Tento p\u0159\u00edstup je v rozporu s imperativn\u00edm p\u0159\u00edstupem charakteristick\u00fdm pro k\u00f3d jQuery.<\/p>\n
V jQuery v\u00fdslovn\u011b uv\u00e1d\u00edte kroky k proveden\u00ed jak\u00fdchkoli zm\u011bn. A v deklarativn\u00edm frameworku \u0159\u00edk\u00e1te: \u00abDle t\u011bchto dat by m\u011blo rozhran\u00ed vypadat takto\u00bb. To m\u016f\u017ee v\u00fdrazn\u011b usnadnit psan\u00ed k\u00f3du bez chyb.<\/p>\n
V\u00fdvoj\u00e1\u0159i p\u0159ijali nov\u00e9 p\u0159\u00edstupy k v\u00fdvoji webov\u00fdch str\u00e1nek, co\u017e vedlo ke sn\u00ed\u017een\u00ed obl\u00edbenosti jQuery.<\/p>\n
Kdy pou\u017e\u00edt jQuery?<\/h2>\n
\nTak kdy tedy by m\u011blo <\/i>b\u00fdt pou\u017eito jQuery?<\/p>\n
Pokud se slo\u017eitost projektu bude zvy\u0161ovat, je lep\u0161\u00ed za\u010d\u00edt s jinou knihovnou nebo frameworkem, kter\u00fd umo\u017e\u0148uje smyslupln\u011b \u0159\u00eddit slo\u017eitost. Nap\u0159\u00edklad odd\u011blit u\u017eivatelsk\u00e9 rozhran\u00ed na komponenty. Pou\u017eit\u00ed jQuery na takov\u00fdch str\u00e1nk\u00e1ch v po\u010d\u00e1te\u010dn\u00edch f\u00e1z\u00edch m\u016f\u017ee vypadat p\u0159ijateln\u00e9, ale rychle to povede k vzniku \u0161pagetov\u00e9ho k\u00f3du, kdy si nebudete jisti, kter\u00fd fragment ovliv\u0148uje kterou \u010d\u00e1st str\u00e1nky.<\/p>\n
Byl jsem v takov\u00e9 situaci, kdy p\u0159i pokusu prov\u00e9st jakoukoli zm\u011bnu vznikal pocit t\u011b\u017ek\u00e9ho \u00fakolu. Nen\u00ed mo\u017en\u00e9 si b\u00fdt jist\u00fd, \u017ee nic nezhod\u00edte, proto\u017ee selektory jQuery z\u00e1vis\u00ed na HTML struktu\u0159e vytv\u00e1\u0159en\u00e9 serverem.<\/p>\n
Na druh\u00e9m konci spektra jsou jednoduch\u00e9 weby, kter\u00e9 vy\u017eaduj\u00ed pouze trochu interaktivity nebo dynamick\u00e9ho obsahu. V takov\u00fdch p\u0159\u00edpadech bych tak\u00e9 nezapnul jQuery jako v\u00fdchoz\u00ed volbu, proto\u017ee pomoc\u00ed nativn\u00edch API lze ud\u011blat mnohem v\u00edce.<\/p>\n
I kdy\u017e budu pot\u0159ebovat n\u011bco mocn\u011bj\u0161\u00edho, budu hledat specializovanou knihovnu, nap\u0159\u00edklad axios<\/a><\/noindex> pro Ajax nebo Animate.css<\/a><\/noindex> pro animace. Bude to jednodu\u0161\u0161\u00ed, ne\u017e na\u010d\u00edtat cel\u00e9 jQuery kv\u016fli mal\u00e9 funk\u010dnosti.<\/p>\n
Mysl\u00edm, \u017ee nejlep\u0161\u00ed od\u016fvodn\u011bn\u00ed pro pou\u017eit\u00ed jQuery je to, \u017ee poskytuje komplexn\u00ed funkcionalitu pro pr\u00e1ci s frontendem webu. M\u00edsto toho, abyste studovali r\u016fzn\u00e1 nativn\u00ed API nebo specializovan\u00e9 knihovny, m\u016f\u017eete si p\u0159e\u010d\u00edst pouze dokumentaci jQuery a okam\u017eit\u011b se st\u00e1t produktivn\u00edmi.<\/p>\n
Imperativn\u00ed p\u0159\u00edstup se \u0161patn\u011b \u0161k\u00e1luje, ale je jednodu\u0161\u0161\u00ed se ho nau\u010dit ne\u017e deklarativn\u00ed p\u0159\u00edstupy jin\u00fdch knihoven. Pro web s jasn\u011b omezen\u00fdmi mo\u017enostmi je lep\u0161\u00ed pou\u017e\u00edt jQuery a bez obav pracovat: knihovna nevy\u017eaduje slo\u017eit\u00e9 sestaven\u00ed nebo kompilaci.<\/p>\n
Krom\u011b toho je jQuery dobr\u00e9 pro p\u0159\u00edpady, kdy si jste jisti, \u017ee web se v pr\u016fb\u011bhu \u010dasu nezkomplikuje, a pokud v\u00e1s netr\u00e1p\u00ed nativn\u00ed funk\u010dnost, kter\u00e1 bezpochyby vy\u017eaduje v\u00edce k\u00f3du ne\u017e jQuery.<\/p>\n
Tuto knihovnu m\u016f\u017eete tak\u00e9 pou\u017e\u00edvat, pokud pot\u0159ebujete podporu star\u0161\u00edch verz\u00ed IE. V takov\u00e9m p\u0159\u00edpad\u011b v\u00e1m jQuery poslou\u017e\u00ed jako v dob\u011b, kdy byl IE nejpopul\u00e1rn\u011bj\u0161\u00edm prohl\u00ed\u017ee\u010dem.<\/p>\n
Pohled do budoucnosti<\/h2>\n
\njQuery je\u0161t\u011b dlouho nezmiz\u00ed. Ona se aktivn\u011b vyv\u00edj\u00ed<\/a><\/noindex>, a mnoz\u00ed v\u00fdvoj\u00e1\u0159i d\u00e1vaj\u00ed p\u0159ednost pou\u017e\u00edv\u00e1n\u00ed jej\u00edho API, i kdy\u017e jsou k dispozici nativn\u00ed metody. Knihovna pomohla cel\u00e9mu generaci v\u00fdvoj\u00e1\u0159\u016f vytv\u00e1\u0159et webov\u00e9 str\u00e1nky, kter\u00e9 funguj\u00ed na jak\u00fdchkoli prohl\u00ed\u017ee\u010d\u00edch. A i kdy\u017e ji v mnoha ohledech nahradily nov\u00e9 knihovny, r\u00e1mce a paradigmy, jQuery sehr\u00e1la obrovskou pozitivn\u00ed roli p\u0159i utv\u00e1\u0159en\u00ed modern\u00edho webu.<\/p>\n
Pokud se funk\u010dnost jQuery podstatn\u011b nezm\u011bn\u00ed, je velmi pravd\u011bpodobn\u00e9, \u017ee v n\u00e1sleduj\u00edc\u00edch n\u011bkolika letech bude pou\u017e\u00edv\u00e1n\u00ed knihovny i nad\u00e1le pomalu, ale jist\u011b klesat. Nov\u00e9 webov\u00e9 str\u00e1nky se obvykle od za\u010d\u00e1tku vytv\u00e1\u0159ej\u00ed pomoc\u00ed modern\u011bj\u0161\u00edch r\u00e1mc\u016f a vhodn\u00e9 sc\u00e9n\u00e1\u0159e pro pou\u017eit\u00ed jQuery se objevuj\u00ed \u010d\u00edm d\u00e1l m\u00e9n\u011b.<\/p>\n
N\u011bkomu se nel\u00edb\u00ed intenzita zastar\u00e1v\u00e1n\u00ed n\u00e1stroj\u016f pro webov\u00fd v\u00fdvoj, ale pro m\u011b je to d\u016fkaz rychl\u00e9ho pokroku. jQuery n\u00e1m umo\u017enila dos\u00e1hnout mnoha v\u011bc\u00ed l\u00e9pe. To plat\u00ed i pro jej\u00ed n\u00e1stupce.
