如何在同一页面上使用几个图像滑块

Question

我创建了一个简单的图像滑块，我正在尝试使其起作用，而不管同一页面上有多少个。我已经尝试了许多方法，但是除非我分开打电话给每个滑块，否则没有任何方法可以正常工作：

JS

var ramonSlider = function(slider, slides, prev, next, transition) {
    var imgSlider = {
        slider: $(slider).data('name'), 
        sliderId: $('#' + $(slider).data('name')),
        slides: $(slides),
        prev: $(prev),
        next: $(next),
        transition: transition || 3000,
        currentIndex: 0,
        interval: undefined,
        slideCount: function() {
            return this.sliderId.find(slides).length;
        },
        makeFirstSlideActive: function() {
            this.sliderId.find(slides).first().addClass('active');
        },
        moveItems: function() {
            var slideItems = this.sliderId.find(slides);
            var currentSlide = slideItems.eq(this.currentIndex);
            console.log(currentSlide);
            slideItems.removeClass('active');
            currentSlide.addClass('active');
        },
        moveOne: function() {
            console.log(this.slideCount());
            var thisObject = this;
            if (this.currentIndex > this.slideCount() - 1) {
                thisObject.currentIndex = 0;
            }
            this.moveItems();
        },
        autoSlide: function() {
            var thisObject = this;
            this.interval = window.setInterval(function() {
                thisObject.currentIndex++;
                thisObject.moveOne();
            }, thisObject.transition);
        },
        moveToNext: function() {
            var thisObject = this;
            var nextItem = this.sliderId.find(next);
            nextItem.on('click', function(e) {
                e.preventDefault();
                window.clearInterval(thisObject.interval);
                thisObject.currentIndex++;
                thisObject.moveOne();              
            });
        },
        moveToPrev: function() {
            var thisObject = this;
            var prevItem = this.sliderId.find(prev);
            prevItem.on('click', function(e) {
                e.preventDefault();
                window.clearInterval(thisObject.interval);
                thisObject.currentIndex--;
                if (thisObject.currentIndex < 0) {
                    thisObject.currentIndex = thisObject.slideCount() - 1;
                }
                thisObject.moveItems();                
            });
        }   
    }
    var init = function() {
        imgSlider.makeFirstSlideActive();
        imgSlider.moveItems();
        imgSlider.moveOne();
        imgSlider.autoSlide();
        imgSlider.moveToNext();
        imgSlider.moveToPrev();
    }
    return init();
};

此起作用(使用滑块的ID调用每个功能(

$(document).ready(function() {
    ramonSlider('#rm-slider-1', '.rm-slider-slide', '.rm-prev', '.rm-next');
    ramonSlider('#rm-slider-2', '.rm-slider-slide', '.rm-prev', '.rm-next');
    ramonSlider('#rm-slider-3', '.rm-slider-slide', '.rm-prev', '.rm-next');
});

我希望它可以工作(一旦使用类而不是IDS调用功能(

$(document).ready(function() {
    ramonSlider('.rm-slider', '.rm-slider-slide', '.rm-prev', '.rm-next');
});

有什么想法？

Answer 1

未经测试，但应起作用：

$(document).ready(function() {
  $('.rm-slider').each(function(){
    ramonSlider(this, '.rm-slider-slide', '.rm-prev', '.rm-next');
  });
});

另外，这三行实际上在您的滑块插件中是错误的：

 ...
 slides: $(slides),
 prev: $(prev),
 next: $(next),
 ...

现在，当您可能只想选择当前滑块中的这些元素时，他们正在选择文档中的所有元素。为此，您可能想用

替换它们

 ...
 slides: $(slides, $(slider)),
 prev: $(prev, $(slider)),
 next: $(next, $(slider)),
 ...

如果它像现在一样起作用，则可能是因为您实际上没有使用this.slides，this.prev或this.next。但是...如果您不使用它们，我认为将它们定义为对象的属性没有任何意义。很可能，如果您完全删除这些行，您的滑块就可以了。

Answer 2

您可以尝试以$。

将其循环

$(document).ready(function() {    
    $('.rm-slider').each(function(){
      ramonSlider(this, '.rm-slider-slide', '.rm-prev', '.rm-next');
    });
});

测试和验证
