2，主页调用，提前调用jquery,再调用slider.js
<script type="text/javascript">
$(function () {
var bannerSlider = new Slider($('#banner_tabs'), {
time: 2000,
delay: 400,
event: 'hover',
auto: true,
mode: 'fade',
controller: $('#bannerCtrl'),
activeControllerCls: 'active'
});
$('#banner_tabs .flex-prev').click(function () {
bannerSlider.prev()
});
$('#banner_tabs .flex-next').click(function () {
bannerSlider.next()
});
$('.悬停的区域').mouseenter(function () {
bannerSlider.stop()
})
$('.悬停离开后').mouseleave(function () {
bannerSlider.autoPlay()
})
})
</script>
