我需要在我的网站上循环浏览4个图像,我不想在网站上添加另一个插件,所以我创建了自己的简单轮播(下面是html,css和js)
我的问题是,仅仅从查看此代码,是否有一个明显更简单/更好的方法来做到这一点?
HTML:
<section id="carousel">
<img src="images/image_00.jpg" width="202" height="162" />
</section>
的CSS:
#carousel{text-align:center;position:relative;}
#carousel img{top:0;left:0;z-index:1;position:absolute;}
JS:
function carousel(el, base_url, images, i){
if (i == images.length ) i = 0;
var el2 = $(el).clone();
$(el).css('z-index', '1');
el2.css('z-index', '0');
el2.attr('src', base_url + images[i]);
$(el).after(el2);
$(el).fadeOut('slow', function(){
$(this).remove();
});
i++;
var func = function(){return carousel(el, base_url, images, i);};
window.timer = setTimeout(func, 4000);
}
$(document).ready(function(){
carousel('#carousel img:first',
'images/',
['image_00.jpg',
'image_01.jpg',
'image_02.jpg',
'image_03.jpg'],
0);
});
答案 0 :(得分:0)
这是我的优化版本......
HTML
<!-- "section" is not valid HTML -->
<div id="carousel">
<img src="images/01.jpg" width="202" height="162" />
</div>
CSS
/* Same as before */
#carousel{text-align:center;position:relative;}
#carousel img{top:0;left:0;z-index:1;position:absolute;}
的Javascript
function carousel(el, base, images, i){
//Made the "i" parameter optional
if (i == images.length || i == null) i = 0;
//Put the variables in a better order
var el2 = $(el).clone();
el2.attr('src', base + images[i]);
el2.css('z-index', '0');
$(el).css('z-index', '1');
$(el).after(el2);
//One line...
$(el).fadeOut('slow', function(){$(this).remove();});
i++;
//The function doesn't have to be in a variable
window.timer = setTimeout(function(){return carousel(el, base, images, i);}, 4000);
}
$(function($){
//Didn't include "i" variable
carousel('#carousel img:first',
'images/',
['01.jpg',
'02.jpg',
'03.jpg',
'04.jpg']);
});
