jQuery ajax request inside fade callback executing multiple times


This is how my HTML looks:

    <ul id="list">
            <li><a href="#one">One</a></li>
            <li><a href="#two">Two</a></li>
            <li><a href="#three">Three</a></li>
    <ul>

And this is my jQuery:

    $("#list li").fadeOut(600, function(){
        $.ajax({
            type: "POST",
            url: "includes/functions/ajax.php",
            data: { id: id },
            dataType: "json",
            })
        .done(function(data){
            otherFunction(data);
        });         
    });

So, I'm trying to hide the list elements and after that run the ajax request. But the problem is that for some reason the ajax request is executing three times. If I remove the fade function the request executes properly (only once), so probably is running as many times as items are on my list, which I find strange. Is that possible? Can you help me to figure out a solution? I really need that ajax request to execute only when the fadeOut function has finished.

I hope I made myself clear and I apologize if I messed up with my english.

Thank you!


Solution

  • The standard animation complete callback is called for each element in the collection.

    If you use .promise() you can queue a callback that will wait until all animations have completed on the given collection:

    $('#myList li').fadeOut('slow', function() {
        console.log('per element');
    }).promise().done(function() {
        console.log('all elements');
    });
