javascript - 在 jCarousel 中允许三个以上的元素

Question

我和下面的问题有同样的问题:

Setting number of visible images in jCarousel

答案好像在css文件里，但是基本上丢给我的网站好像不太规范。

这是我的 .js 代码:

我在哪里可以找到 CSS 文件？我在整个文件结构中搜索了文本，但找不到这些方法

.jcarousel-skin-ie7 .jcarousel-container-horizontal
{
    width:750px;
}

.jcarousel-skin-ie7 .jcarousel-clip-horizontal {
    width:740px; 
}

更多代码...:

if(this.options.carousel){
                //default options for carousel
                var carouselDefaults = {vertical:this.options.carouselVertical, initCallback: function(carousel){
                    jQuery(carousel.list).find('img').click(function(e,x) {
                    if(typeof(x) !== 'undefined' && x.how == "auto"){
                        if(self.options.autoPlay == false){
                            return false;
                        }
                    }
                    var clicked = parseInt(jQuery(this).parents('.jcarousel-item').attr('jcarouselindex'));
                    var last = (jQuery(this).parents('ul').find('li:last').attr('jcarouselindex') == clicked-1) ? true : false;
                    if(!last){
                        clicked = (clicked-2<=0) ? 0 : clicked-2;
                    }
                    clicked++;
                    carousel.scroll(clicked);
                });
            }};

我相信这段代码指向轮播选项，我应该在其中进行这些更改。

          var carouselOptions = $.extend({}, carouselDefaults, this.options.carouselOptions || {visible: 6});
          this.list.jcarousel(carouselOptions);

        }
        if(typeof(this.options.buildFinished) == 'function'){
            this.options.buildFinished(this);
        }
    }, //end setup

这是上面引用的代码:

 var defaults = {
    autoPlay: true,
    speed: 5000,
    text: { play: "", stop: "", previous: "Previous", next: "Next", loading: "Loading" },
    transition:[1],
    showCaption: true,
    IESafe: false,
    showTooltips: false,
    carousel: false,
    carouselVertical: false,
    animationFinished: null,
    buildFinished: null,
    bindsFinished: null,
    startOn: 0,
    thumbOpacity: 0.4,
    hoverPause: false,
    animationSpeed: 600,
    fadeThumbsIn: false,

  carouselOptions: {visible: 6},

    thumbChangeEvent: 'click.pikachoose',
    stopOnClick: false
};

Answer 1

您在传递的 javascript 选项中设置它，如下所示:

jQuery('#mycarousel').jcarousel({visible: 4});

这会将可见项的数量设置为四个。

在这里查看 jsFiddle:

要找到它，请在您的元素/文件系统中搜索 ).jcarousel(。这将向您显示调用代码的位置，只需将其添加到上面的调用中即可。
