我用我从网上捡到的比特制作了一个自定义的 jQuery 轮播,但我无法让它正常工作。
所发生的只是旋转木马工作但一直向左滑动。经过一些调试后,我发现 carousel_ul 的左侧继续减去图像宽度,但没有像我认为的那样返回到 -960。
我在这里看到了一些关于轮播的文章,但没有一篇使用我想要的方法。
这是我的代码:
HTML:
<div id="carousel_container">
<div id="carousel_inner">
<ul id="carousel_ul">
<li>
<img src="http://static.shopify.com/s/files/1/0167/9164/t/5/assets/carousel-item-1.jpg?1321" alt="" />
</li>
<li>
<img src="http://static.shopify.com/s/files/1/0167/9164/t/5/assets/carousel-item-2.jpg?1321" alt="" />
</li>
<li>
<img src="http://static.shopify.com/s/files/1/0167/9164/t/5/assets/carousel-item-3.jpg?1321" alt="" />
</li>
<li>
<img src="http://static.shopify.com/s/files/1/0167/9164/t/5/assets/carousel-item-4.jpg?1321" alt="" />
</li>
</ul>
</div>
</div>
CSS:
#carousel_ul {
position:relative;
left:-960px; /* important (this should be negative number of list items width(including margin) */
list-style-type: none; /* removing the default styling for unordered list items */
margin: 0px;
padding: 0px;
width:9999px; /* important */
/* non-important styling bellow */
padding-bottom:0px;
}
#carousel_ul li{
float: left; /* important for inline positioning of the list items */
width:960px; /* fixed width, important */
/* just styling bellow*/
padding:0px;
height:300px;
background: #000000;
margin-top:0px;
margin-bottom:0px;
margin-left:0px;
margin-right:0px;
}
#carousel_ul li img {
.margin-bottom:-4px; /* IE is making a 4px gap bellow an image inside of an anchor (<a href...>) so this is to fix that*/
/* styling */
cursor:pointer;
cursor: hand;
border:0px;
}
jQuery:
jQuery(document).ready(function ($) {
//rotation speed and timer
var speed = 2000;
var run = setInterval('rotate()', speed);
jQuery('#carousel_ul li:first').before(jQuery('#carousel_ul li:last'));
});
//a timer will call this function, and the rotation will begin :)
function rotate() {
var item_width = jQuery('#carousel_ul li').outerWidth() ;
//calculate the new left indent of the unordered list
var left_indent = parseInt(jQuery('#carousel_ul').css('left')) - item_width;
//alert(left_indent);
//make the sliding effect using jquery's anumate function '
jQuery('#carousel_ul').animate({'left' : left_indent},{queue:false, duration:1000},function(){
//get the first list item and put it after the last list item (that's how the infinite effects is made) '
jQuery('#carousel_ul li:last').after(jQuery('#carousel_ul li:first'));
//and get the left indent to the default -960px
jQuery('#carousel_ul').css({'left' : '-960px'});
});
}
它是从几个例子中被屠杀的。
碰巧我无法按我的意愿工作。
