一页上有多个滑块

2012-03-11

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:

HTML

#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>

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);

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。
