Multiple sliders on one page

问题

Ok, I builded a slider in javascript and Jquery (with help of you guys) But now I want to have multiple sliders on 1 page. While using just one javascript. BUT...the slider can be different in width (or number of items): also the name of the slider is different because of the css width.

So How do I use 1 javascript to controle different sliders

Here is my code:

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">&laquo;</button></div><div id="move_right"><br><br><button id="left">&raquo;</button></div>

    <div id="block1">7</div>    
    <div id="block2">8</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);

This should be fine:

(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);

In theory you could do some code which can take a selector to a wrapper element (which has the required slider elements inside) as some parameter. And then you can from this element create selectors which are more dynamic. I'm not sure where you get "step = 500" from, but that's maybe something you could grab dynamically from some relevant element.
