DateUtil.getDate(year,month,day) 輸入?yún)?shù)為年、月、日，返回一個JS的Date型對象
7

DateUtil.formateDate(pattern,date) 輸入?yún)?shù)一個是格式化字符串，比如"yyyy-MM-dd"，和JS日期對象，輸出格式化后的日期字符串（基本上和Java的格式化類似）
8

DateUtil.formateDateTime(pattern,date) 參數(shù)類型同上，但是該方法是在要格式化包含時間的時候使用，如"yyyy-MM-dd HH-mm-ss"
9

DateUtil.isLeapYear(date) 輸入一個JS日期型參數(shù)，判斷該日期所在的年是不是閏年
