Question

I have this following jquery text fly-in animation.Here is my code before I explain further:

<script type="text/javascript">

$(document).ready(function(){

    $('.flying1 .flying-text').css({opacity:0});
    $('.flying1 .active-text').animate({opacity:1, marginLeft: "0px"}, 1200); //animate first text
    var int = setInterval(changeText, 3500);    // call changeText function every 5 seconds

function changeText(){  
    var $activeText = $(".flying1 .active-text");     //get current text    
    var $nextText = $activeText.next();  //get next text

    if ($activeText.is('.end')) {
        $activeText.stop().delay(5000);
        $('.flying1').html('<div class="flying-text active-text">Text4<div>
                                <div class="flying-text">Text5</div>
                                <div class="flying-text end2">Text6</div>');
        $('.flying1 .flying-text').css({opacity:0});
        $('.flying1 .active-text').animate({opacity:1, marginLeft: "0px"}, 1200); //animate first text
    };

    if ($activeText.is('.end2')) {
        $activeText.stop().delay(5000);
        $('.flying1').html('<div class="flying-text active-text">Text1<div>
                                <div class="flying-text">Text2</div>
                                <div class="flying-text end">Text3</div>');
        $('.flying1 .flying-text').css({opacity:0});
        $('.flying1 .active-text').animate({opacity:1, marginLeft: "0px"}, 1200); //animate first text
    };

    $nextText.css({opacity: 0}).addClass('active-text').animate({opacity:1, marginLeft: "0px"}, 1200, function(){

        $activeText.removeClass('active-text');                                           
    });
}
});
</script>

HTML

<div class="flying-text active-text">Text1<div>
<div class="flying-text">Text2</div>
<div class="flying-text end">Text3</div>

Now as you can see, Text1-3 animates/flies in first, then when Text3 is reached, they are replaced by Text4-6 in the animation, when Text6 is reached again, it loops back to Text1-3 again…Now basically what I want to do is pause/delay the animation for longer when it reaches the end of the Text, that is at Text3(class=”flying-text end”) and Text6(class=”flying-text end2″. So I want Text3 and Text6 to animate longer than all the others. how do I do that? The code I used :

$activeText.stop().delay(5000);

does not work…

Thank You

I think you’ve made things over-complicated for yourself.

You just need to use normal setTimeout to trigger the next animation, but do that within the animation “complete” function to ensure that you’re not mixing animation timers with normal timers.

You should also avoid setInterval for the same reason – it’ll fall out of sync with any animation timers, particularly when the jQuery authors revert back to using requestAnimationFrame.

Here’s my solution:

var text = [
    ['Text1', 'Text2', 'Text3'],
    ['Text4', 'Text5', 'Text6']
    ];

var n = 0,
    page = 0;
var $f = $('.flying-text');

function changeText() {
    $f.eq(n).text(text[page][n]).css({
        opacity: 0,
        marginLeft: '-50px'
    }).animate({
        opacity: 1,
        marginLeft: "0px"
    }, 1200, function() {
        if (++n === 3) {
            page = 1 - page;
            n = 0;
            setTimeout(function() {
                $f.empty();
                changeText();
            }, 6000);
        } else {
            setTimeout(changeText, 2000);
        }
    });
};

changeText();​

Note that this completely separates the text content from the animation logic.
