Inkinga enkulu ngonyaka we-copyright ka-Footer ukuthi kungaba nzima ukucacisa ukuthi umsebenzi othile washicilelwa nini okokuqala. Lokhu kungaba ulwazi olubalulekile lokunquma ukuthi umsebenzi uyakufanelekela yini ukuvikelwa kwe-copyright.
The copyright year in the footer can be updated automatically by using JavaScript.
var d = new Date();
document.getElementById("copyrightyear").innerHTML = d.getFullYear();
Le khodi ithola unyaka wamanje entweni yedethi, bese ibuyekeza isici sonyaka we-copyright ngalowo nyaka.
Ukuhlwaya
Ukuhlaziya ku-JavaScript kuyinqubo yokuguqula iyunithi yezinhlamvu yombhalo ibe into noma amalungu afanayo. Kunezindlela eziningi ezihlukene zokuhlaziya umbhalo ku-JavaScript, futhi indlela ejwayeleke kakhulu ukusebenzisa umsebenzi we-String.parse().
Umsebenzi we-String.parse() uthatha iyunithi yezinhlamvu njengokufakwayo futhi ibuyisela into noma amalungu afanayo aqukethe umbhalo odlulisiwe. Isibonelo esilandelayo sibonisa indlela yokusebenzisa umsebenzi we-String.parse() ukuze uhlukanise iyunithi yezinhlamvu equkethe uhlu lwezinombolo:
var izinombolo = “1, 2, 3, 4, 5”;
var parsedNumbers = String.parse(izinombolo);
Into ye-paredNumbers iqukethe ulwazi olulandelayo:
– Inombolo 1 iqukethwe phakathi kwesici sokuqala sento ehlukanisiwe yezinombolo (isb., “1”).
– Inombolo 2 iqukethwe phakathi kwesici sesibili sento ehlukanisiwe yeNumeri (isb., “2”).
- Inombolo 3 iqukethwe phakathi kwesici sesithathu sento ehlukanisiwe yezinombolo (isb., "3").
Imeyili
I-imeyili iyindlela enhle yokugcina uthintana nabangane nomndeni. Futhi kuyindlela enhle yokuthumela imilayezo emaqenjini amakhulu abantu. Kulesi sifundo, sizofunda ukuthi ungawenza kanjani umlayezo we-imeyili ku-JavaScript.
Okokuqala, sizodinga izingcezu ezimbalwa zolwazi. Sizodinga ikheli le-imeyili lomamukeli, isihloko se-imeyili, kanye nomlayezo ngokwawo. Singathola la manani ngokusebenzisa umsebenzi we-window.alert().
Okulandelayo, sizodala umsebenzi ozodala umlayezo wethu we-imeyili. Umsebenzi uzothatha izimpikiswano ezintathu: ikheli le-imeyili lomamukeli, isihloko se-imeyili, kanye nomlayezo ngokwawo.
Ekugcineni, sizosebenzisa umsebenzi we-send() ukuthumela umlayezo wethu we-imeyili. Umsebenzi we-send() uthatha izimpikiswano ezimbili: ikheli le-imeyili lomamukeli kanye nomlayezo ngokwawo.
