I have an array of URLs and I want to open all these URLs one by one in the new tab with the specified delay. I have tried the below method, but it opens all URLs in a one-shot after a delay of 2 seconds. Please suggest the code changes.
items = ["a.com", "b.com", "c.com", "d.com"]
items.forEach((url, index) => {
if (index <= 49) {
setTimeout(() => { window.open(url, "_blank"); }, 2000);
}
})
Use async function for that.
Sample Implementation.
items = ["a.com", "b.com", "c.com", "d.com"];
function resolveAfter2Seconds(index) {
return new Promise(resolve => {
setTimeout(() => {
window.open(items[index], "_blank")
resolve('resolved');
}, 2000);
});
}
async function asyncCall() {
console.log('calling');
let index = 0;
while (index < items.length) {
const result = await resolveAfter2Seconds(index);
console.log(result);
// expected output: "resolved"
index++;
}
}
asyncCall();
