How to add pause between each iteration of jQuery .each()?
JquerySettimeoutEachJquery Problem Overview
I'm grabbing an array of jQuery objects and then via .each() modifying each individual jquery with in the array.
In this case I'm updated the class names to trigger a -webkit-transition-property to utilize a css transition.
I'd like there to be a pause before each css transition begins. I'm using the following, but there is no delay in between each update. Instead, they all appear to be updating at once.
function positionCards() {
$cards = $('#gameboard .card');
$cards.each(function() {
setTimeout( function(){ addPositioningClass($(this)); }, 500 )
});
}
function addPositioningClasses($card){
$card
.addClass('position')
}
I was hoping setTimeout would solve this, but it doesn't seem to be working. Is there a way to accomplish the pause before each CLASS name update of each object?

I added this as a comment but now that I have read it correctly and answered my own question this would probably work:
function positionCards() {
var $cards = $('#gameboard .card');
var time = 500;
$cards.each(function() {
setTimeout( function(){ addPositioningClass($(this)); }, time)
time += 500;
});
}

Sorry for digging up an old thread, but this tip could be useful for similar issues:
$cards.each(function(index) {
$(this).delay(500*index).addClass('position');
});

If you make a method that calls itself every 500 ms that should do that trick. The following code should work.
var __OBJECTS = [];
$('#gameboard .card').each(function() {
__OBJECTS.push($(this));
});
addPositioningClasses();
function addPositioningClasses() {
var $card = __OBJECTS.pop();
$card.addClass('position');
if (__OBJECTS.length) {
setTimeout(addPositioningClasses, 500)
}
}

How about .delay() ?
or
function addPositioningClasses($card){
setTimeout(function() { $card.addClass('position')}, 1000);
}

If you're only targeting Safari/iOS, depending on how important it is to you to control the exact timing of animation sequences, you should maybe avoid any solution that involves JS timeouts. There is no guarantee that the animation will complete at the same time as the timeout delay, particularly on slow processors or machines that have lots of stuff going on in the background. Later versions of webkit (including mobile safari) do allow for timed animation sequences via @-webkit-keyframes
. Webkit.org has a nice intro to it. It's actually pretty easy to implement.

Give this a try:
function positionCards() {
$('#gameboard .card').each(function() {
$(this).delay(500).addClass('position');
});
}
I'll be honest... I've had $(this).delay() misbehave in the past in certain instances and work flawlessly in others. However, this was normally in conjunction with jQuery animation calls, not DOM attribute manipulation.
Please be aware .delay() does not function in the same way as setTimeout. For more information, see the jQuery .delay() documentation.
As far as I am aware, $().each does execute procedurally so the next iteration of the call should only begin after the preceding has completed.

Check this out, worked well for me! :)
jQuery('.optiresultsul li').each(function(index) {
jQuery(this).delay(500*index).animate({ opacity: 1 }, 500,function(){
jQuery(this).addClass('bgchecked');
});
});

This code will add set the inital delay to 50ms. Then for each loop through the ".row" class it will add an additional 200ms delay. This will create a nice delayed show effect for each row.
$( document ).ready(function() {
// set inital delay
var dtotal = 50;
$(".row").each(function() {
//add delay to function
$(this).delay(dtotal).show();
//add 200ms to delay for each loop
dtotal = dtotal + 200;
});
});
