Eyona ngxaki iphambili ngonyaka welungelo lokukopisha i-Footer kukuba kunokuba nzima ukumisela ukuba umsebenzi othile wapapashwa nini okokuqala. Oku kunokuba lulwazi olubalulekileyo lokugqiba ukuba ngaba umsebenzi ufanelekile na ukukhuselwa kwelungelo lokushicilela.
The copyright year in the footer can be updated automatically by using JavaScript.
var d = new Date();
document.getElementById("copyrightyear").innerHTML = d.getFullYear();
Le khowudi ifumana unyaka okhoyo kwi-Date object, kwaye emva koko ihlaziye i-copyright year element ngaloo nyaka.
Ukwahlula
Ukwahlulahlula kwiJavaScript yinkqubo yokuguqula umtya wokubhaliweyo ube yinto okanye uluhlu. Kukho iindlela ezininzi ezahlukeneyo zokwahlula okubhaliweyo kwiJavaScript, kwaye eyona ndlela iqhelekileyo kukusebenzisa iString.parse () umsebenzi.
I-String.parse () umsebenzi uthatha umtya njengegalelo kwaye ibuyisela into okanye uluhlu oluqulathe umbhalo ocaluliweyo. Lo mzekelo ulandelayo ubonisa indlela yokusebenzisa i String.parse () umsebenzi wokwahlulahlula umtya oqulathe uluhlu lwamanani:
var amanani = “1, 2, 3, 4, 5”;
var parsedNumbers = String.parse(amanani);
Into ecazululiweyo yamanani iqulathe olu lwazi lulandelayo:
– Inani loku-1 liqulethwe kwindawo yokuqala yento ecaluliweyo yamanani (umzekelo, “1”).
– Inani lesi-2 liqulethwe phakathi kwesiqalelo sesibini sento ecaluliweyo yamanani (umz., “2”).
Inombolo yesi-3 iqulethwe kwindawo yesithathu yento ecaluliweyo yamanani (umz., “3”).
I-imeyile yindlela entle yokunxibelelana nabahlobo kunye nosapho. Ikwayindlela entle yokuthumela imiyalezo kumaqela amakhulu abantu. Kule tutorial, siya kufunda ukwenza umyalezo we-imeyile kwiJavaScript.
Okokuqala, siya kufuna iinkcukacha ezimbalwa. Siza kufuna idilesi ye-imeyile yomamkeli, umxholo we-imeyile, kunye nomyalezo ngokwawo. Singafumana la maxabiso ngokusebenzisa i window.alert() umsebenzi.
Okulandelayo, siya kudala umsebenzi oza kudala umyalezo wethu we-imeyile. Umsebenzi uya kuthatha iingxoxo ezintathu: idilesi ye-imeyile yomamkeli, umxholo we-imeyile, kunye nomyalezo ngokwawo.
Okokugqibela, siya kusebenzisa i send() umsebenzi ukuthumela umyalezo wethu we-imeyile. Thumela () umsebenzi uthatha iingxoxo ezimbini: idilesi yemeyile yomamkeli kunye nomyalezo ngokwawo.
