好吧，我用 javascript 和 Jquery 构建了一个 slider (在你们的帮助下)，但现在我想在一页上有多个 slider 。虽然只使用一种 JavaScript。但是... slider 的宽度(或项目数量)可以不同:由于 css 宽度， slider 的名称也不同。
那么我如何使用 1 个 JavaScript 来控制不同的 slider
这是我的代码:
HTML
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
<style type="text/css">
#temp{
height: 300px;
}
#container{
width: 500px;
height: 150px;
background:#CDFAA8;
overflow:hidden;
position:absolute;
left: 13px;
}
#slider{
width: 800px;
height: 150px;
background:#063;
position:absolute;
left: 0px;
}
#block1{
width: 100px;
height: 150px;
background:#067;
float: left;
}
#block2{
width: 100px;
height: 150px;
background:#079;
float: left;
}
#move_right{
height: 150px;
width: 20px;
background: #3f3f3f;
position: absolute;
right:0px;
z-index: 200;
opacity: 0.2;
}
#move_left{
height: 150px;
width: 20px;
background: #3f3f3f;
position: absolute;
left:0px;
z-index: 200;
opacity: 0.2;
}
</style>
</head>
<body>
<div id="temp">
<div id="container">
<div id="move_left"><button id="right">«</button></div><div id="move_right"><br><br><button id="left">»</button></div>
<div id="slider">
<div id="block1">1</div>
<div id="block2">2</div>
<div id="block1">3</div>
<div id="block2">4</div>
<div id="block1">5</div>
<div id="block2">6</div>
<div id="block1">7</div>
<div id="block2">8</div>
</div>
</div>
</div>
<div id="slider">
<div id="block1">1</div>
<div id="block2">2</div>
<div id="block1">3</div>
<div id="block2">4</div>
<div id="block1">5</div>
<div id="block2">6</div>
<div id="block1">7</div>
<div id="block2">8</div>
</div>
</div>
</div>
JavaScript
(function($) {
var slider = $('#slider'),
step = 500,
left = parseInt(slider.css('left'), 10),
max = $('#container').width() - slider.width(),
min = 0;
$("#left").click(function() {
if (left > max) {
var newLeft = left - step;
left = (newLeft>max) ? newLeft : max;
$("#slider").animate({
"left": left + 'px'
}, "slow");
}
});
$("#right").click(function() {
if (left < 0) {
var newLeft = left + step;
left = (newLeft<min) ? newLeft : min;
slider.animate({
"left": left + 'px'
}, "slow");
}
});
})(jQuery);
最佳答案
这应该没问题:
(function($) {
$('#temp #container').each(function(){
var slider = $(this).find('#slider'),
parent = $(this),
step = 500,
left = parseInt(slider.css('left'), 10),
max = parent.width() - slider.width(),
min = 0;
parent.find("#left").click(function() {
if (left > max) {
var newLeft = left - step;
left = (newLeft>max) ? newLeft : max;
slider.animate({
"left": left + 'px'
}, "slow");
}
});
parent.find("#right").click(function() {
if (left < 0) {
var newLeft = left + step;
left = (newLeft<min) ? newLeft : min;
slider.animate({
"left": left + 'px'
}, "slow");
}
});
});
})(jQuery);
