封装的常用方法，
| 方法名 | 参数 | 介绍 |
| judgeNull | value | 判断空值，包括{}和[]，空为true，否则为false |
| judgeString | value | 判断是否为字符串类型，是为true，否则为false |
| judgeNumber | value | 判断是否为数字类型，是为true，否则为false |
| judgeBoolean | value | 判断是否为布尔类型，是为true，否则为false |
| judgeArray | value | 判断是否为数组类型，是为true，否则为false |
| judgeObject | value | 判断是否为对象类型，是为true，否则为false |
| judgeFunction | value | 判断是否为方法类型，是为true，否则为false |
| mergeObject | ob1,ob2... | 合并对象，深层克隆 |
| getApp | 同微信官方getApp | |
| getCurrentPages | 同微信官方getCurrentPages | |
| getCurrentPage | 获取当前页 | |
| getCurrentPath | 获取当前页路径 | |
| getPath | targetPath | getRelativePath的简易封装，不需要当前路径，只需要目标路径 |
| getRelativePath | currentPath,targetPath | 获取两个路径之间相对路径 |
| getTimestamp | 获取时间戳 | |
| getClassName | object key对应class，value对应true或false | 获取class的方法，使用方法同ng，比较方便多class生成 |
