I’m trying to implement a jQuery function with an infinite loop to animate a div. I can’t figure out how to do it. This is my code:

$(document).ready(function () {
    $('#divers').animate({
        'margin-top': '90px'
    }, 6000).animate({
        'margin-top': '40px'
    }, 6000);
});

put the code that does the full animation into a function, then pass that function as the callback param to the last animation. Something like...

$(document).ready(function() {   
    function animateDivers() {
        $('#divers').animate(
            {'margin-top':'90px'}
            ,6000
        )
        .animate(
            {'margin-top':'40px'}
            ,6000
            ,animateDivers //callback the function, to restart animation cycle
        ); 
    }

    animateDivers(); //call, to start the animation
});

$(document).ready(function() {
    function ani() {
        $('#divers').animate({
               'margin-top':'90px'
            },6000).animate({
               'margin-top':'40px'
           },6000, ani); //call the function again in the callback
        }); 
    }); 
    ani();
});

use the .animate() callback to 'recall' your function:

jsBin demo

$(function() {
  
  
  function loop(){
   $('#divers')
     .animate({marginTop:90},6000)
     .animate({marginTop:40},6000, loop); // callback
  }
  
  loop(); // call this wherever you want


});

Using setInterval is the way to go. Too much recursion will just get you "Stack Overflow" :-) "Uncaught RangeError: Maximum call stack size exceeded"

The animate() function has an option to take a function to call when the animation ends. You could just do the same call, and voila.

You can also set the set interval function specifying which method to call at what interval

$(function () { setInterval(fnName, 6000); });
