沫鱼 人气:0用jquery封装了一个控制图片左右滚动的插件，有左右按钮可以点击实现图片滚动效果。
代码如下：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>slide</title>
<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.6.2/jquery.min.js"></script><br><style>
* {
padding:0;
margin:0;
list-style: none
}
img{
border: none
}
#img-slider, #img-slider-2 {
position: relative;
width: 560px;
height: 80px;
}
.slider-wrap {
width: 480px;/*width的值要跟所有的li宽度总和一样*/
overflow: hidden;
position: relative;
height: 150px;
margin-left: 40px;
}
.slider-wrap ul {
zoom: 1;
position: absolute;
left: 0;
top: 0;
width: 9999px;
}
.slider-wrap ul li {
float: left;
width: 120px;
text-align: center;
padding: 5px 0;
}
#prev, #next {
position: absolute;
top: 30px;
left: 0px;
width: 40px
}
#next {

right: 0px
}
</style><br><script type="text/javascript">
$(function () {
$("#img-slider").imgScroll();
$("#img-slider-2").imgScroll();
});
/*插件*/
(function ($) {
$.fn.imgScroll = function () {
var isDone = false,
scrollBox = $(this),
prevBtn = scrollBox.find("#prev"),
nextBtn = scrollBox.find("#next"),
imgBox = scrollBox.find("ul"),
next_over = imgBox.find("li").width() * imgBox.find("li").length,
slide_width = $(".slider-wrap").width();
return this.each(function(){
function setOpacity() {
imgBox.animate({
opacity: 1
}, 800,function(){
isDone = false;
})
}
function scrollNext() {
if(!isDone && next_over + parseInt(imgBox.css("left"),10) > slide_width){
isDone = true;
imgBox.animate({
left: "+=" + "-" + slide_width,
opacity: 0.5
}, 800, setOpacity);
}
//isDone = false
}
function scrollPrev() {
if(!imgBox.is(':animated') && parseInt(imgBox.css("left"),10) !=0){
imgBox.animate({
left: "+=" + slide_width,//不断左移
opacity: 0.5
}, 800, setOpacity);
}
}
prevBtn.bind('click', scrollPrev); //向前滚动
nextBtn.bind('click', scrollNext); //向后滚动
})
}
})(jQuery);
