尝试将功能彼此分离或隔离

时间：2018-07-17 03:52:54

标签： javascript jquery html

基本上，我正在构建的功能或滑块会触发其他滑块。因此，如果我单击next按钮。所有其他滑块将滑动。我目前正在尝试弄清楚如何使用.each()和this来使功能彼此分离或隔离，因此，如果我创建多个元素，可以说slider不会影响其他元素

(function ($) {
    'use strict';

    var Slider = {

        init : function() {
            
            this.$sliderBanner = $('.slider-banner');


            $('.slider-banner').each(function() {
                var position = 0;
                this.$sliderItemsWrapper = $('.slider-items' , this);
                this.$slides = $('.slides', this.$sliderItemsWrapper);
                this.$sliderButtons = $('.arrow');
                this.totalSlides = $('.slides', this.$sliderItemsWrapper).length;
    
                this.sliderBannerWidth = $(this).width();
                this.$setSliderWrapperWidth = $(this.$sliderItemsWrapper).width( this.sliderBannerWidth * this.totalSlides );
        
                this.$slides.width(this.sliderBannerWidth);
                var that = this;
       
                $('.arrow.-prev').on('click', function(){
                    position --;
                    if ( position == -1 ) { position = that.totalSlides - 1; }
                    that.$sliderItemsWrapper.css('left', - (that.sliderBannerWidth * position));  
                    console.log(position);
                });
    
                $('.arrow.-next').on('click', function() {
                    position ++;
                    if (position == that.totalSlides) { position = 0; }
                    that.$sliderItemsWrapper.css('left', - (that.sliderBannerWidth * position));  
                    console.log(position);
                });                
            });
        },
    };

   
 
    $(document).ready(function() {

        Slider.init();
    });

})(jQuery);

答案 0 :(得分：2)

一个简单的代码修补程序，请确保您绑定了正确的元素。

更改：

this.$sliderButtons = $('.arrow');至this.$sliderButtons = $('.arrow',this);

$('.arrow.-prev').on('click', function(){至$('.arrow.-prev',this).on('click', function(){

$('.arrow.-next').on('click', function(){至$('.arrow.-next',this).on('click', function(){

答案 1 :(得分：0)

您需要在唯一元素上绑定滑块（可以使用属性名称，id或唯一的jQuery选择器来完成）。只需在Slider.Init（）中传递元素，如代码所示。因此，无论何时为该特定元素初始化滑块，它都将在父div范围内，并且只有该特定滑块会移动。
