即一条新闻滚 进视图之后，会暂停几秒钟，然后继续向上2滚动，淡出视图，同时，下一条新闻接着滚入视图。这次主要是用jquery来开发这个功能，里面肯定有许多不足 之处，欢迎大家点评。
先粘贴一下代码，
')
.addClass('publication-date')
.text(pubMonth + '/' + pubDay + '/' + pubYear);
var $summary = $('')
.addClass('summary')
.html($('description', this).text());
$('')
.addClass('headline')
.append($headline, $publication)
.appendTo($container);
});
var currentHeadline = 0, oldHeadline = 0;
var hiddenPosition = $container.height() + 10;
$('div.headline').eq(currentHeadline).css('top', 0);
var headlineCount = $('div.headline').length;
var pause;
var headlineRotate = function() {
currentHeadline = (oldHeadline + 1) % headlineCount;
$('div.headline').eq(oldHeadline).animate(
{top: -hiddenPosition}, 'slow', function() {
$(this).css('top', hiddenPosition);
});
$('div.headline').eq(currentHeadline).animate(
{top: 0}, 'slow', function() {
pause = setTimeout(headlineRotate, 4000);
});
oldHeadline = currentHeadline;
};
pause = setTimeout(headlineRotate, 4000);
$container.hover(function() {
clearTimeout(pause);
}, function() {
pause = setTimeout(headlineRotate, 3000);
});
});
});
});
