Inkinga enkulu ehlobene nokusebenzisa ikhodi ngemva kokulayisha kwekhasi ukuthi ikhodi ingase ingakwazi ukufinyelela ku-DOM noma isimo somhlaba wonke sekhasi. Lokhu kungaholela emaphutheni noma ekuziphatheni okungalindelekile.
If you want to run some code after the page has loaded, you can use the window.onload event:
window.onload = function() { // code goes here };
Le khodi ichaza umsebenzi okufanele uqalise ngemva kokuba ikhasi selilayishiwe. Umsebenzi wabelwe umcimbi we-window.onload, okuzowubangela ukuthi uqalise ngemva kokuba ikhasi selilayishiwe.
Ama-fuctions
Ku-JavaScript, imisebenzi iyindlela yokuhlanganisa amakhodi ahlobene ndawonye. Lokhu kwenza kube lula ukufunda nokugcina ikhodi yakho.
Umsebenzi uthatha impikiswano eyodwa noma ngaphezulu. Lawa ma-agumenti okokufaka okuzosetshenziswa umsebenzi ukwenza umsebenzi wawo.
Uma umsebenzi usubizwa, uzosebenza uze ubuyise inani noma uhlangabezane nephutha. Uma ibuyisela inani, lelo nani ngokuvamile ligcinwa kokuguquguqukayo. Uma kwenzeka iphutha, umyalezo wephutha uvame ukuvezwa kumsebenzisi.
Imisebenzi ingasetshenziswa ukudala izingcezu ezincane zekhodi ezingasetshenziswa kabusha ngokuhamba kwesikhathi. Lokhu kwenza ikhodi yakho ihleleke kakhulu futhi ifundeke kalula.
Iyini imisebenzi
Umsebenzi uyibhulokhi yekhodi eyenza umsebenzi othile. Imisebenzi ichazwa ku-JavaScript kusetshenziswa umsebenzi wegama elingukhiye. Imisebenzi ingathatha impikiswano eyodwa noma ngaphezulu, okungamanani umsebenzi ozowasebenzisa ukuze wenze umsebenzi wawo.
Imisebenzi emikhulu
Ku-JavaScript, imisebenzi esemqoka yile:
1. Igama elingukhiye lomsebenzi
2. Isitatimende sembuyiselo
3. Isitatimende se-var
4. Ucingo lomsebenzi
5. Leli gama elingukhiye
