在另一个JS函数中调用easySlider动画函数

我正在努力为 easySlider 制作客户的下一个和上一个链接。我在滑块 JS 文件中找到了动画函数。但我尝试从我自己的 JS 函数中调用它。我收到函数未定义错误。 这是滑块的 JS 代码。

(function($) {

    $.fn.easySlider = function(options){

        // default configuration properties
        var defaults = {            
            prevId:         'prevBtn',
            prevText:       'Previous',
            nextId:         'nextBtn',  
            nextText:       'Next',
            controlsShow:   true,
            controlsBefore: '',
            controlsAfter:  '', 
            controlsFade:   true,
            firstId:        'firstBtn',
            firstText:      'First',
            firstShow:      false,
            lastId:         'lastBtn',  
            lastText:       'Last',
            lastShow:       false,              
            vertical:       false,
            speed:          800,
            auto:           false,
            pause:          2000,
            continuous:     false
        }; 

        var options = $.extend(defaults, options);  

        this.each(function() {  
            var obj = $(this);              
            var s = $("li", obj).length;
            var w = $("li", obj).width(); 
            var h = $("li", obj).height(); 
            obj.width(w); 
            obj.height(h); 
            obj.css("overflow","hidden");
            var ts = s-1;
            var t = 0;
            $("ul", obj).css('width',s*w);          
            if(!options.vertical) $("li", obj).css('float','left');

            if(options.controlsShow){
                var html = options.controlsBefore;
                if(options.firstShow) html += '<span id="'+ options.firstId +'"><a href=\"javascript:void(0);\">'+ options.firstText +'</a></span>';

                };

            };
            // init
            var timeout;
            if(options.auto){;
                timeout = setTimeout(function(){
                    animate("next",false);
                },options.pause);
            };      

            if(!options.continuous && options.controlsFade){                    
                $("a","#"+options.prevId).hide();
                $("a","#"+options.firstId).hide();              
            };              

        });

    };

})(jQuery);

我尝试调用的函数是“animate” 我的函数调用在这里,

animate("next",false);

您能指导我如何进行正确的函数调用吗?

I am struggling to make custome next and prev links for easySlider. I found animate function in slider JS file. But i try to call it from my own JS function. I get function not defined error.
Here is JS code for slider.

(function($) {

    $.fn.easySlider = function(options){

        // default configuration properties
        var defaults = {            
            prevId:         'prevBtn',
            prevText:       'Previous',
            nextId:         'nextBtn',  
            nextText:       'Next',
            controlsShow:   true,
            controlsBefore: '',
            controlsAfter:  '', 
            controlsFade:   true,

            };              

        });

    };

})(jQuery);

And function which i am trying of call is "animate"
my function call is here

animate("next",false);

Can you guide me how to make proper function call?

这个解决方法怎么样:

$('#nextBtn a').click();

$('#prevBtn a').click();

工作方式类似于charm(假设您没有更改下一个/上一个按钮元素的 CSS Id)

How about this work around:

$('#nextBtn a').click();

And

$('#prevBtn a').click();

Works like a charm (assuming you have not altered the CSS Ids of the next/prev button elements)
