我有5张照片幻灯片正在运行,我想在滑动到第4张照片时执行animate()功能。幻灯片显示在滑动到第4个幻灯片时停止,而不是运行animate();发生什么事了?
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.cycle.all.js"></script>
<script type="text/javascript">
$(function() {
$('#slideshow').cycle({
fx: 'fadeZoom',
timeout: 2000,
pagerAnchorBuilder: function(idx, slide) {
// return sel string for existing anchor
return '#nav li:eq(' + (idx) + ') a';
} ,
after: onAfter,
});
});
function onAfter(curr,next,opts) {
var caption = (opts.currSlide + 1);
$('#caption').html(caption);
var number = $('#caption').html();
if(caption == "4"){
$('#nav_content').animate({
left: pos.left - 180
}, 500);
};
};
</script>
谢谢!

忘记在函数中定义变量“pos”。现在它按预期工作。

var number = $('#caption').html();
var c = $('#nav_content');
var pos = c.position();
var w = c.width();
var status = w + pos.left;
var dif = w - 190;
var x = w + dif;
if(caption == "4"){
$('#nav_content').animate({
left: pos.left - 180
}, 500);
};
if(caption == "1" & pos.left < 0){
$('#nav_content').animate({
left: pos.left + 180
}, 500);
};
};
