Salut,
Doresc sa pun un Sleep/Delay de 1 sec in "while" dar nu reusesc. Ma puteti ajuta cu codul bun? Multumesc!
<script>
function scrollWin() {
var i = 0;
while (i < 10) {
window.scrollBy(0, 10);
...................................................(sleep 1000)
i++;
}
}
</script>

Nu se face asa. Reorganizezi codul astfel incat fiecare parte care se executa neinterupt sa fie o functie separata. Apoi utilzezi setTimeout() sau setInterval(), dupa caz, pentru a executa ‘bucatile’ in ordinea in care trebuie - fiecare ‘bucata’ o programeaza la executie, dupa intervalul necesar de timp, pe urmatoarea.

cu async/await
const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));
async function scrollWin(){
while{
...
await sleep(1000);
}
}

Am incercat cu setTimeout() si setInterval() dar nu am reusit. Pana la urma a mers varianta lui "alx42". Multumesc!
const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));
async function scrollWin(){
var i = 0;
while (i < 10) {
window.scrollBy(0, 10);
await sleep(1000);
i++;
}
}
HTML <button onclick="scrollWin()">Scroll</button> Edited by alex05ok, 26 May 2020 - 07:04. |

Am reusit si cu setTimeout()
function scrollWin() {
var i = 0;
while (i < 10) {
(function(i) {
setTimeout(function() {
window.scrollBy(0, 10);
}, 1000 * i)
})(i++)
}
}
