二、jquery源码：
(function($){
//扩展这个方法到jquery;
$.fn.extend({
//将可选择的变量传递给方法
slideimg: function(options) {
//参数和默认值
var defaults = {
tol_class:'.goleftbtn', //获得点击左按钮的class
tor_class:'.gorightbtn', //获得点击右按钮的class
slide_class:'.slide_tolr', //获得滑动层的class
center_class:'.star', //获得中间点的class
maxnum:'5' //最多滑动次数；
};
var options = $.extend(defaults, options);
var count;
var checkname;
//遍历匹配元素的集合
return this.each(function() {
var o =options;
//获得最外层的ID;
var thisid = $(this).attr("id");
var slidebar = $($(this).find(o.slide_class),$(this));
var goleftbtn = $($(this).find(o.tol_class),$(this));
var gorightbtn = $($(this).find(o.tor_class),$(this));
var clickCenter = $($(this).find(o.center_class),$(this));
//设置可见层的宽
o.slide_wid = slidebar.parent().width()
//设置滑动层的宽；
slidebar.css("width",o.slide_wid*o.maxnum+"px");
$(goleftbtn).click(function(){
if(count > 1){
count--;
$("#"+ thisid +" "+o.center_class+" img").css("opacity","0.3");
$("#"+ thisid +" "+o.center_class + count + " img").css("opacity","0.95");
slidebar.animate({left:'-' + o.slide_wid*(count-1)},{queue:false});
}else{
count = o.maxnum;
slidebar.animate({left:'-' + o.slide_wid*(count-1)},{queue:false});
$("#"+ thisid +" "+o.center_class+" img").css("opacity","0.3");
$("#"+ thisid +" "+o.center_class + count + " img").css("opacity","0.95");
}
});
$(gorightbtn).click(function(){
if( count < o.maxnum){
count++;
slidebar.animate({left:'-' + o.slide_wid*(count-1)},{queue:false});
$("#"+ thisid +" "+o.center_class+" img").css("opacity","0.3");
$("#"+ thisid +" "+o.center_class + count + " img").css("opacity","0.95");
}else{
slidebar.animate({left:'0'},{queue:false});
count = 1;
$("#"+ thisid +" "+o.center_class+" img").css("opacity","0.3");
$("#"+ thisid +" "+o.center_class + count + " img").css("opacity","0.95");

});
})(jQuery);
