Is it possible to wait for the completion of processing during the following loop and proceed to the next step?
$. each (array, function (i, val) {
1. Perform time-consuming processes such as AJAX
2. When processing is complete, proceed to the next loop
});
If i setsetTimeout, the following loop process may be executed before the process ends.
$. each (array, function (i, val) {
setTimeout (function () {
Execute processing
}, 1000 * key);
});
