Saacadda Stopwatch Online oo Bilaash ah

Sida Ay U Shaqeyso

Saacaddan waqtiga qabta gebi ahaanba wuxuu ka shaqeeyaa biraawsarka isagoo isticmaalaya API-ga performance.now() ee biraawsarka ku dhex jira — saacad heer-sarreysa oo hal-jiho ah — oo uu wado loop requestAnimationFrame ah oo dib u sawira muuqaalka animation-frame kasta (caadi ahaan 60 jeer ilbiriqsi kastaba). Server midna kuma lug lahan wakhti kasta.

1. 1
   performance.now() wuxuu qiyaasaa wakhtiga

   Marka aad gujiso Start, qalabku wuxuu diiwaan geliyaa dhibic tixraac ah oo leh performance.now(). Animation-frame kasta, muuqaalku wuxuu ka jaraa tixraacaas qiimaha performance.now() hadda si loo xisaabiyo millisecond-yada dhacay — isagoo ka fogaanaya dhibaatooyinka leexashada saacadda ee ka dhasha wicitaannada isdaba-joog ah ee setInterval.
2. 2
   requestAnimationFrame wuxuu wadaa muuqaalka

   Halkii saacad xilli-go'an ah, akhriska lambarka waxaa lagu cusboonaysiiyaa loop requestAnimationFrame ah. Tani waxay muuqaalka ku sii haysaa isla-mid-u-socodka rendering-ka biraawsarka laftiisa, sidaa darteed counter-ka centiseconds-ku si dhaqso ah ayuu u socdaa wuxuuna weligiis ka degdeg badnaan waayaa waxa shaashadu cusboonaysiin karto.
3. 3
   localStorage wuxuu sii hayaa fadhi socda

   Dhacdo bilow, joojin, ama lap kasta, qalabku wuxuu snapshot ku qoraa localStorage — oo ay ku jirto taariikh-wakhti tixraac ah oo derbiga ah. Haddii aad dib u shubto bogga intii socodku socdo, saacaddu waxay akhrisaa tixraacaas, waxay xisaabisaa immisa millisecond ay soo dhaafeen tan iyo markii la qoray, waxayna ka sii socotaa wakhtiga saxda ah.
4. 4
   Laps waxaa loo soo saari karaa qoraal tab-lagu-kala-jaray ama CSV

   Lap kastaa wuxuu keydiyaa wakhtigiisa kala-jarid (delta laga bilaabo lap-kii hore) iyo wadarta isdaba-joogga ah. Copy All wuxuu safafka tab-lagu-kala-jaray ugu qoraa clipboard-ka via navigator.clipboard.writeText; Download CSV wuxuu soo saaraa Blob leh BOM UTF-8 ah si faylku sax ugu furmo Excel iyada oo aan loo baahnayn saaxiibka soo-gelinta.
