获取轮播滑块中的第二张图片 JQuery
Get the second image in the carousel slider JQuery
我正在使用 http://web.enavu.com/demos/carousel.html 的轮播。我希望第一个左边的图像不透明度:1,其余不透明度:0.5。 :)
有人可以帮忙吗?
谢谢。
<script type="text/javascript">
$(document).ready(function() {
//move he last list item before the first item. The purpose of this is if the user clicks to slide left he will be able to see the last item.
$('#carousel_ul li:first').before($('#carousel_ul li:last'));
//when user clicks the image for sliding right
$('#right_scroll img').click(function(){
//get the width of the items ( i like making the jquery part dynamic, so if you change the width in the css you won't have o change it here too ) '
var item_width = $('#carousel_ul li').outerWidth() + 10;
//calculae the new left indent of the unordered list
var left_indent = parseInt($('#carousel_ul').css('left')) - item_width;
//make the sliding effect using jquery's animate function '
$('#carousel_ul:not(:animated)').animate({'left' : left_indent},500,function(){
//get the first list item and put it after the last list item (that's how the infinite effects is made) '
$('#carousel_ul li:last').after($('#carousel_ul li:first'));
//and get the left indent to the default -210px
$('#carousel_ul').css({'left' : '-210px'});
});
});
});

<div id='carousel_container'>

<li><a href='#'><img src='item1.png' /></a></li>

在jquery中,用
抓住中心项目
var middle = $('li').get(2);
这将始终 return 中心项目。就在这个查询之后 运行
$(middle).css('opacity, .2'); // adjust the translucency of the image
将onclick="changeMiddle()"
添加到每个箭头按钮以触发此功能:
function changeMiddle()
{
var middle = $('li').get(2); // fetch middle image
$('li').css('opacity', '1'); // correct previous transparencies
$(middle).css('opacity', '.2'); // make middle image transparent
}
