javascript - jQuery plug-in production, multiple calls on one page

Question

I want to write a carousel image plug-in. I called it twice on my page... Each one passed in three images, but when I looped it out and added it to the page, I found that there were 6 li. Now I want to The desired effect is that I loop once and add 3 li to the first one. The second time I add the corresponding li to the second one. I hope a passing expert can give me some advice....

            $(".xxx_carousel").xxx_carousel({
                $picObj: {
                    "1": "showImgItem",
                    "2": "showImgItem cyan",
                    "3": "showImgItem red"
                }
            });

            $(".xxx_carousel").xxx_carousel({
                indicatorLeftText: '左',
                indicatorRightText: '右',
                $picObj: {
                    "4": "showImgItem",
                    "5": "showImgItem cyan",
                    "6": "showImgItem red"
                }
            });

(function($, window, document, undefined) {

var defaults = {
    navEvents: 'click',
    indicatorEvents: 'click',
    indicator: true,
    indicatorLeftText: 'left',
    indicatorRightText: 'right',
    animateSpeed: 800,
    $picObj: {},
    $cb: null
};

var xxx_carousel = function(ele, ops) {
    this.$ele = ele;
    this.settings = $.extend({}, defaults, ops);
    var _this = this;
    this.initaddElem();
}

xxx_carousel.prototype = {
    initaddElem: function(){
        var $picTemplate = '',
            $carouselPicWarp = $(".xxx_carousel_pic_warp"),
            _this = this;
            // --> 这个地方会循环两次 我页面调用的时候传了两个$picObj
            // --> 但是我发现循环时候它是直接在每个$(".xxx_carousel_pic_warp")下面添加了六个li 我现在想要的效果就是循环第一次 给我的第一个这个类名的加三个li,
            // --> 循环第二次的时候给我第二个类名的加三个li 而不是一次添加6个.... 这个该是怎么解决的呢？？
            $.each(this.settings.$picObj, function(i, val) {
                $picTemplate += '<li class="xxx_carousel_warp_item"><a class="' + val + '" href="javascript:;">' + i + '</a></li>'
            })
            $carouselPicWarp.append($picTemplate)
    }

}

$.fn.xxx_carousel = function(opts) {
    var xxxCarousel = new xxx_carousel(this, opts);
    return xxxCarousel;
}

})(jQuery, window, document)

The class names of your two elements are both .xxx_carousel, so when you bind $(".xxx_carousel"), both will be bound at the same time. The correct approach is: only the first time Select the first binding, select the second binding a second time, and that's it.

$(".xxx_carousel:eq(1)").xxx_carousel({ // 注意:eq(1)，也可以用jQuery的.eq(1)或者first()
    $picObj: {
        "1": "showImgItem",
        "2": "showImgItem cyan",
        "3": "showImgItem red"
    }
});

$(".xxx_carousel:eq(2)").xxx_carousel({ // 注意:eq(2)，也可以用jQuery的.eq(2)，由于总共只有两个，也可以用jQuery的.last()
    indicatorLeftText: '左',
    indicatorRightText: '右',
    $picObj: {
        "4": "showImgItem",
        "5": "showImgItem cyan",
        "6": "showImgItem red"
    }
});
