我平时测试习惯调用在线jquery,地址如下,容易记。
<script src="http://code.jquery.com/jquery-latest.js"></script>
版本为:v1.11.1,在jscroll.js库不支持该版本的jquery。应当使用高版本的。jQuery 1.2.3测试没问题。
一定是先调用$("#reward_info").show();把弹层显示出来,再调用$(".num-list").jscroll()方法显示滚动条。
因为原理是要获得内容的高度。在调用show前,没有渲染,得不到高度,显示不出滚动条。
当内容高度变化时,需及时调用$(".num-list").jscroll()刷新才能正确显示。
