我有以下 jQuery 横幅旋转器脚本,我想对其进行一些更改,以便横幅每 X 秒旋转一次,即使用户没有单击上一个/下一个按钮。当前代码在这里:
<script type="text/javascript">
var active_banner_index = 0;
function banner_next(direction) {
var banners = $(".banner-content");
if( banners.length ) {
var curr = $(banners[active_banner_index]);
active_banner_index+=direction;
if( active_banner_index>=banners.length )
active_banner_index = 0;
if( active_banner_index<0 )
active_banner_index = banners.length-1;
next = $(banners[active_banner_index]);
curr.fadeOut(1000,
function() {
next.fadeIn(500);
}
);
}
}
$(document).ready(function() {
var tbl = $("#mega-hot-deal-666");
var tag_left = $("#hot-deal-arrow-left");
var tag_right = $("#hot-deal-arrow-right");
var banners = $(".banner-content");
if( banners.length ) {
$(banners[0]).show();
}
pos = tbl.position();
tag_left.css('z-index',100);
tag_left.css({
position: "absolute",
top: pos.top+67, left: pos.left-37,
cursor: "pointer"
});
tag_right.css('z-index',6);
tag_right.css({
position: "absolute",
top: pos.top+67, left: pos.left+tbl.width()-26,
cursor: "pointer"
});
active_banner_index = 0;
tag_left.click( function(){ banner_next(-1); } );
tag_right.click( function(){ banner_next(1); } );
});
</script>
我必须添加什么代码才能使横幅自行旋转,而无需等待用户单击按钮?
