在调整大小时尝试使我的旋转木马滑块响应

Question

I've managed to build my own carousel with loop for a website I'm working. Right now my next objective is to make it responsive and fluid when resizing. I've managed to make it adaptive but I just do not like the way how it resizes specifically based on the browser dimension instead of having resize fluidly. Here is a sample of the code that I've been working on.

I'm trying to make the items resize and slide based on the number of items shown. Lets say if it's a 768px viewport it will show 3 items and slide the carousel by 3 and if its mobile say 640px or 480px. It will show 1 item and slide by 1

I know there are already ready made carousel out there but I would prefer to try and build it by scratch

 (function ($) { 'use strict'; var carousel = { init : function() { var carouselWidth = 0, itemListContainer = $('.item-list').width(), itemList = $('.carousel .item-list ul li'); // Set Container Width $('.carousel .item-list ul').children().each(function() { carouselWidth += $(this).outerWidth(); $('.carousel .item-list ul').width(carouselWidth + 1000); }); // function dynamicItemWidth() { // if ( $('body') <= 1024 ) { // itemWidth = itemList.width( itemListContainer / 5 ); // } // if ( $('body') <= 480 ) { // itemWidth = itemList.width( itemListContainer / 2 ); // } // if ( $('body') <= 320 ) { // itemWidth = itemList.width( itemListContainer / 1 ); // } // } var itemWidth = itemList.width( itemListContainer / 5 ), itemSize = itemWidth.width(); $('.carousel .item-list ul').prepend( $('.carousel .item-list ul li:last') ); $('.carousel .item-list ul').css('left', '-' + itemSize + 'px'); $('.btns .next').click(function(){ var move = $('.carousel .item-list ul li').outerWidth(); var leftIndent = parseInt($('.carousel .item-list ul').css('left')) - move; function animate( repeat, speed ) { $('.carousel .item-list ul:not(:animated)').animate({'left' : leftIndent}, speed,function(){ $('.carousel .item-list ul').append( $('.carousel .item-list ul li:first') ); $('.carousel .item-list ul').css({'left' : '-' + move + 'px'}); if ( repeat > 1 ) { animate( ( repeat - 1 ), speed ); } }); } animate( 5, 100 ); }); $('.btns .prev').click(function() { var move = $('.carousel .item-list ul li').outerWidth(); var leftIndent = parseInt($('.carousel .item-list ul').css('left')) + move; function animate( repeat, speed ) { $('.carousel .item-list ul:not(:animated)').animate({'left' : leftIndent}, speed,function(){ $('.carousel .item-list ul').prepend($('.carousel .item-list ul li:last')); $('.carousel .item-list ul').css({'left' : '-' + move + 'px'}); if ( repeat > 1 ) { animate( ( repeat - 1 ), speed ); } }); } animate( 5, 100 ); }); } } $(document).ready(function(){ carousel.init(); }); })(jQuery);

Answer 1

Your approach has gone in wrong directions at several places. Resizing all the containers using JavaScript can be avoided & you can let css do the work. I can't submit a quality answer to this without rewriting the whole plugin.

If you need, I can write a version that relies on CSS than JavaScript (which is preferable & adaptable in most cases) and follows the "Module Structure" of JavaScript plugins.

Please refer this article to learn a bit about the proper structuring of code.

Answer 2

Why waste time building your own carousel? There are already ready made solutions to help you with. Try Slick Slider , it's one of the best I've used. :)

Answer 3

Agree with MegaColorBoy

http://kenwheeler.github.io/slick/

This is a better one to go with, also this gives better compatibility over the mobile devices.

Also if you want to write from scratch than write something new :) all the best.
