そして、次のスクリプト

}
setInterval(function(){ tick () }, 8000);
</script>

問題は、テキストがうまくフェードアウトするのに、一瞬で再表示されることです。どうにかフェードインもスムーズに。

それ以外の：

$(this).appendTo($('#ticker')).css('opacity', 1);

次のようなことをします：

$(this).appendTo($('#ticker')).animate({'opacity' : 1}, 2000);

FIDDLEを確認してください

function tick() {
    $('#ticker li:first').animate({
        'opacity': 0
    },2000, function() {
        $(this).appendTo($('#ticker')).animate({'opacity' : 1}, 2000);
    });
}
setInterval(function() {
    tick()
}, 8000);​

It would be easier and more concise if you used the jQuery effects .fadeIn(time_in_ms) & .fadeOut(time_in_ms). More info here: http://api.jquery.com/fadeIn/ & http://api.jquery.com/fadeOut/.

example: $('#ticker li:first').fadeIn(1000);

How about this?

var $ticker = $('#ticker'); // save the static element
function tick(){
    $ticker.children().first().fadeOut(2000, function () {
        $(this).appendTo($ticker).fadeIn(500);
    });
}
setInterval(tick, 8000);

I think what you want is something more like this:

var $ticker = $('#ticker'); // save the static element
$ticker.children(':not(:first-child)').hide();

function tick(){
    $ticker.children(':first-child').fadeOut(1000, function () {
        $(this).appendTo($ticker);
        $ticker.children().first().fadeIn(1000);
    });
}
setInterval(tick, 8000);

One item is shown at a time, and the displayed item fades out then the next item fades in.

var $ticker = $('#ticker');

$ticker.children(':not(:first-child)').hide();

関数ティック(){

$ticker.children(':first-child').fadeOut(1000, function () {

    $(this).appendTo($ticker);

    $ticker.children().first().fadeIn(1000);

});

} setInterval(ティック、8000)
