前段时间,网易云音乐上线了一个基于熟人社交投票玩法的 h5 活动,该活动依据投票数权重值来划分格子块,并通过格子块之间无缝挤压动效极大地增加了趣味性。本文将着重介绍如何基于 treemap(矩形树图)来实现一个稳定的动态格子块挤压效果以及在这其中遇到的一些问题。
TreeMap的内容: {1=Python, 2=JavaScript, 3=Java} 1. 在这个例子中,我们创建了一个TreeMap,并添加了三个键值对。由于TreeMap根据键的自然顺序进行排序,所以输出的键值对已经按升序排列。 获取TreeMap中的元素 你可以使用get()方法根据键获取对应的值。如果键不存在,get()方法返回null。
