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
