(function ( $ ) {
    
    $.fn.iscroll=function(options){
        var settings = $.extend({
      s:45
    }, options );
        $this=this;

3.注意事项

1.不要在调用方法的元素上(示例中.iscroll)使用padding内上下边距

2.里层的<li>元素不要使用外边距但可以使用内边距

4. <style type="text/css"> /** * * IE6中需要这样设置才会起作用 */ *{ margin: 0; padding: 0; } </style>
