Question

我正在尝试创建一个包含不同电影的轮播的响应式页面。我希望能够按流派过滤电影，并且只在旋转木马中显示一个选定的类型。

我一开始尝试使用bootstrap轮播，但似乎使用jQuery光滑滑块是要走的路。但我也读过一些人在使用具有响应式设计的光滑时遇到问题。

这可能是ja文件中的原因，因为我会收到以下错误：

"Uncaught TypeError: $(...).slickUnfilter is not a function
    at HTMLButtonElement.<anonymous> (slider.js:31)
    at HTMLButtonElement.dispatch (jquery-1.11.0.min.js:3)
    at HTMLButtonElement.r.handle (jquery-1.11.0.min.js:3)
(anonymous) @ slider.js:31
dispatch @ jquery-1.11.0.min.js:3
r.handle @ jquery-1.11.0.min.js:3"

Answer 1

您收到JavaScript错误的原因是您未正确指定对各种slick方法的引用。您需要使用以下格式.slick('[methodName]')。例如：

// Incorrect
$('.movies-carousel').slickUnfilter();

// Correct
$('.movies-carousel').slick('slickUnfilter');

以下代码应该可以帮助您。

$(document).ready(function() {
    $('.movies-carousel').slick();
});

$('.movies-button').on('click', function() {
    var filtername = $(this).parent('li').attr('id');
    var currentclass = $(this).attr('class');

    if (currentclass == 'btn btn-xs btn-default movies-button') {
        // currently filtered, turn the others off and this on
        $('.movies-carousel').slick('slickUnfilter');
        $('.movies-carousel').slick('slickFilter', '.filter-' + filtername);
        $('.movies-carousel').slick('slickGoTo', 0);
        $('.movies-button').attr('class', 'btn btn-xs btn-default movies-button');
        $(this).attr('class', 'btn btn-xs btn-primary movies-button');
    } else {
        // is this the only currently selected movie or are they all active?
        var numberactive = $('.genres').find('.btn-default').length;
        if (numberactive > 0) {
            // toggle them all back on
            $('.movies-carousel').slick('slickUnfilter');
            $('.movies-carousel').slick('slickGoTo', 0);
            $('.movies-button').attr('class', 'btn btn-xs btn-primary movies-button');
        } else {
            // switch the others off
            $('.movies-carousel').slick('slickUnfilter');
            $('.movies-carousel').slick('slickFilter', '.filter-' + filtername);
            $('.movies-carousel').slick('slickGoTo', 0);
            $('.movies-button').attr('class', 'btn btn-xs btn-default movies-button');
            $(this).attr('class', 'btn btn-xs btn-primary movies-button');
        }
    }
});
