Ingxaki ephambili enxulumene nokuqhuba ikhowudi emva komthwalo wephepha kukuba ikhowudi ayinakho ukufikelela kwi-DOM okanye imeko yehlabathi jikelele yephepha. Oku kunokukhokelela kwiimpazamo okanye ukuziphatha okungalindelekanga.
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 khowudi ichaza umsebenzi oza kuqhutywa emva kokuba iphepha lilayishiwe. Umsebenzi wabelwe umcimbi wefestile.onload, oya kubangela ukuba iqhube emva kokuba iphepha lilayishiwe.
IiFuctions
KwiJavaScript, imisebenzi yindlela yokuhlanganisa ikhowudi enxulumeneyo kunye. Oku kwenza kube lula ukufunda nokugcina ikhowudi yakho.
Umsebenzi uthatha impikiswano enye okanye ngaphezulu. Ezi ngxoxo ngamagalelo apho umsebenzi uza kusebenzisa ukwenza umsebenzi wawo.
Wakuba ubizwa umsebenzi, iyakuqhuba ide ibuyisele ixabiso okanye idibane nemposiso. Xa ibuyisela ixabiso, elo xabiso lidla ngokugcinwa kwinguqu. Xa kukho impazamo, umyalezo wemposiso udla ngokuboniswa kumsebenzisi.
Imisebenzi ingasetyenziselwa ukwenza amaqhekeza amancinci ekhowudi angaphinda asetyenziswe kamva. Oku kwenza ikhowudi yakho ilungelelaniswe ngakumbi kwaye kulula ukuyifunda.
Yintoni na imisebenzi
Umsebenzi yibhloko yekhowudi eyenza umsebenzi othile. Imisebenzi ichazwe kwiJavaScript kusetyenziswa igama elingundoqo. Imisebenzi inokuthatha iingxoxo enye okanye ezininzi, ezingamaxabiso apho umsebenzi uza kusebenzisa ukwenza umsebenzi wawo.
Imisebenzi ephambili
KwiJavaScript, imisebenzi ephambili yile:
1. Igama elingundoqo lomsebenzi
2. Ingxelo yembuyekezo
3. Ingxelo ye var
4. Ifowuni yomsebenzi
5. Eli gama lingundoqo
