2、引入文件
<script type="text/javascript" src="${ctx}/resource/javascript/common/jquery.min.js"></script> <script type="text/javascript" src="${ctx}/resource/javascript/common/jquery.nicescroll.min.js"></script>
注意：先引入jq文件，再引入jquery.nicescroll.min.js插件的文件。
3、最简单的用法如下：
<script> $(document).ready( function() { //$("#sidebar")为需要插入滚动条的节点 $("#sidebar").niceScroll({ cursorcolor: "rgba(255,255,255,0.5)",//设置滚动条滑块的颜色 cursorborder: "1px solid rgba(255,255,255,0.5)", // CSS方式定义滚动条边框颜色 }); } ); </script>
注意：一定要放在 $(document).ready 中进行初始化！
4、常用方法
（1）隐藏滚动条
$("#mydiv").getNiceScroll().hide();
（2）检测滚动条是否重置大小（当窗口改变大小时）
$("#mydiv").getNiceScroll().resize();
（3）滚动到某个位置
$("#mydiv").getNiceScroll(0).doScrollLeft(x, duration); // Scroll X Axis
$("#mydiv").getNiceScroll(0).doScrollTop(y, duration); // Scroll Y Axis
（4）可增加各种参数
$(document).ready( function() { $("#thisdiv").niceScroll({cursorcolor:"#00F"}); } );
5、配置参数表
$("#thisdiv").niceScroll({
cursorcolor: "#424242", // 改变滚动条颜色，使用16进制颜色值
cursoropacitymin: 0, // 当滚动条是隐藏状态时改变透明度, 值范围 1 到 0
cursoropacitymax: 1, // 当滚动条是显示状态时改变透明度, 值范围 1 到 0
cursorwidth: "5px", // 滚动条的宽度，单位：便素
cursorborder: "1px solid #fff", // CSS方式定义滚动条边框
cursorborderradius: "5px", // 滚动条圆角（像素）

preventmultitouchscrolling: true // 防止多触点事件引发滚动
});
