jQuery的画廊翻身下一步和previous按钮 [英] jQuery gallery turn over with next and previous buttons
问题描述
我试图做一些画廊，翻身脚本使用jQuery的。为此我得到一个数组 - 比方说13 - 图片：
i'm trying to do some kind of Gallery-Turn Over Script with jQuery. Therefor i got an array with - let's say 13 - images:
galleryImages = new Array(
'images/tb_01.jpg',
'images/tb_02.jpg',
'images/tb_03.jpg',
'images/tb_04.jpg',
'images/tb_05.jpg',
'images/tb_06.jpg',
'images/tb_07.jpg',
'images/tb_08.jpg',
'images/tb_09.jpg',
'images/tb_10.jpg',
'images/tb_11.jpg',
'images/tb_12.jpg',
'images/tb_13.jpg'
);
我的画廊看起来像显示一次只有9图像的网格。我现在已经脚本在计数李#gallery元素的数量，加载第9张图像，并显示它们。该HTML如下：
My gallery looks like a grid showing only 9 images at once. My current script already counts the number of li-elements in #gallery, loads the first 9 images and displays them. The HTML looks like this:
<ul id="gallery">
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
<ul id="gallery-controls">
<li id="gallery-prev"><a href="#">Previous</a></li>
<li id="gallery-next"><a href="#">Next</a></li>
</ul>
我是pretty新的jQuery的我的问题是，我无法弄清楚如何在部分阵列9元件分开，将其连接作为控制按钮的链接。我需要的是这样的：
I'm pretty new to jQuery an my problem is that i can't figure out how to split the array in portions with 9 elements to attach it as a link on the control buttons. I need something like this:
$('#gallery-next').click(function(){
$('ul#gallery li').children().remove();
$('ul#gallery li').each(function(index,el){
var img = new Image();
$(img).load(function () {
$(this).css('display','none');
$(el).append(this);
$(this).fadeIn();
}).attr('src', galleryImages[index]); //index for the next 9 images?!?!
});
});
感谢您的帮助！
推荐答案
试试这个：
<html>
<head>
<style>
#gallery-prev, #gallery-next{text-decoration:underline;color:Blue;cursor:pointer;list-style:none;display:inline;padding:5px;}
#gallery li{list-style:none;display:inline;}
</style>
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript">
galleryImages = new Array(
'images/tb_01.jpg','images/tb_02.jpg','images/tb_03.jpg',
'images/tb_04.jpg','images/tb_05.jpg','images/tb_06.jpg',
'images/tb_07.jpg','images/tb_08.jpg','images/tb_09.jpg',
'images/tb_10.jpg','images/tb_11.jpg','images/tb_12.jpg',
'images/tb_13.jpg');
function loadImages(p) {
var startIndex = parseInt($('ul#gallery').attr("startIndex")) + 9 * p;
if (startIndex < 1 || startIndex >= galleryImages.length) return;
$('ul#gallery')
.attr('startIndex', startIndex)
.find("li").children().remove().end()
.each(function(i, el) {
var nextID = startIndex - 1 + i;
if (nextID >= 0 && nextID < galleryImages.length) {
$(this).append($("<img src='" + galleryImages[nextID] + "' alt='image " + (nextID + 1) + "' />"));
}
});
}
$(document).ready(function() {
$('ul#gallery').attr('startIndex', '1');
for (var i = 1; i <= 9; i++)
$('ul#gallery').append("<li></li>");
loadImages(0);
$('li#gallery-prev, li#gallery-next').each(function(i) {
$(this).click(function() {
loadImages(i == 1 ? 1 : -1);
})
});
});
</script>
</head>
<body>
<ul id="gallery"></ul>
<ul id="gallery-controls">
<li id="gallery-prev">Previous</li>
<li id="gallery-next">Next</li>
</ul>
</body>
</html>
