How to Jquery each complete

问题

I did not do the complete in $.each(). how this is done ? Please help me

$("element").each(function (i, v) {
        //No problem
    }, function () {
        //How to complete finished ??
        // alert(each finish);
    })

回答1:

To execute code after the each loop is over :

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:

$('.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);

回答4:

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:

$('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.

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 .each call. You're over thinking it.

$('.el').each(function () {
  $(this).something();
});
alert('Done');
