JavaScript, AJAX, jQuery › Zjednodušení (spojení) více…
25. 3. 2020   #385721

Ahoj,

začínám s javascriptem a s AJAXem. Mám server na arduinu a několik AJAX skriptů (bez jQuery) obsluhující webovou stránku (odesílání formulářů, aktualizace bloků, atd..). Většina skriptů se liší jen v počtu odesílaných proměnných, nebo v elementech, do kterých vpisuje informace.

Poradíte mi prosím, jak správně spojit tyto funkce, tak aby byl zápis co nejkratší? Určite nemusím v každé jednotlivé funkci kontrolovat odpověď serveru,


if (this.readyState == 4) { if (this.status == 200) { if (this.responseText != null)......
 

ale stačila by mi na to jedna funkce na kontrolu odpovědi serveru a poté volat podfunkce. Dále je podle mě zbytečné mít na každý formulář vlastní funkci, zase by stačila funkce na odesílání formulářů a podfunkce pro konkrétní formulář, atd..

Opravte mně pokud se pletu.

Díky za tipy.
