一页上有多个滑块

好的,我在 javascript 和 Jquery 中创建了一个滑块(在你们的帮助下),但现在我想在 1 个页面上有多个滑块。虽然只使用一个 javascript。但是...滑块的宽度(或项目数量)可以不同:滑块的名称也因 css 宽度而不同。
那么如何使用 1 个 javascript 来控制不同的滑块
这是我的代码:

(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'

}
});
})(jQuery);

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);

理论上,您可以编写一些代码,将选择器作为参数带到包装器元素(其中包含所需的滑块元素)。然后您可以从这个元素创建更动态的选择器。我不确定您从哪里获得“step = 500”,但这可能是您可以从某个相关元素动态获取的东西。
