To execute code after the eachloop is over :
在each循环结束后执行代码：
var count = $("element").length;
$("element").each(function (i) {
// loop
if (i+1 === count) {
// this will be executed at the end of the loop
}
});

The promise()method is usually for AJAX, but it can be used with each()to achieve what you want:
该promise()方法通常用于 AJAX，但它可以用于each()实现您想要的：
$('.element').each(function (key, val) {
console.log('Do something to each individual .element');
}).promise().done(function () {
console.log('Did things to every .element, all done.');
});

You can simply use $.when( $.each() ).then(myFunc, failFunc);
你可以简单地使用 $.when( $.each() ).then(myFunc, failFunc);

Simply check the index of the element, i, with the number of element at the end of the .each()loop. If it matches, then you are done with looping:
只需检查元素的索引i, 以及.each()循环末尾的元素数。如果匹配，那么您就完成了循环：
$('element').each(function (i, v) {
// Do all the stuff here
// Check if you are at the last item
if ($('element').length === i+1) {
// Code to execute when you are at the last item
}
});

Maybe a late response. But this might come in handy There is a package that does what you want.
可能回复晚了。但这可能会派上用场有一个包可以满足您的需求。
var myObject = { // or your array
1 : 'My first item',
2 : 'My second item',
3 : 'My third item'
}
Await.each(myObject, function(key, value){
//your logic here
});
Await.done(function(){
console.log('The loop is completely done');
});

$(document).ready(function(){
let control = $(".container").find("#result");
const setPromise = new Promise(function(resolve,reject){
if(control.length){
resolve("Not Problem...")
}
else{
reject("WTF")
}
})
setPromise.then(function(answer){
console.log(answer)
}).catch(function(answer){
console.log(answer)
})
})

Just put what you want to do after the .eachcall. You're over thinking it.
只需在.each通话后放上您想做的事情即可。你想多了。
$('.el').each(function () {
$(this).something();
});
alert('Done');
