js获取日期yyyy年mm月后台转换

问题描述：昨天做miniui的程序，遇到一个问题，获取日期，类型为yyyy年mm月eg:2015年09月，空间获取值的时候是2015年09月,传给后台查询的时候，类似于这种日期的格式好像oracle数据库没有转换方法，这时候就要借助java字符串的替换方法replcace方法，str.replace('年',"").replace("月",""),这样转换后就变成201509,这样就可以使用oracle日期格式转换了，完美的解决了中文日期转换问题。

附API：

replacepublic String replace(char oldChar,             char newChar)Returns a new string resulting from replacing all occurrences of oldChar in this string 

with newChar. If the character oldChar does not occur in the character sequence represented by this String object, then a 

reference to this String object is returned. Otherwise, a new String object is created that represents a character sequence identical to the character sequence represented by this String object, except that every occurrence of oldChar is replaced by an occurrence of newChar. Examples:  "mesquite in your cellar".replace('e', 'o')         returns "mosquito in your collar" "the war of baronets".replace('r', 'y')         returns "the way of bayonets" "sparring with a purple porpoise".replace('p', 't')         returns "starring with a turtle tortoise" "JonL".replace('q', 'x') returns "JonL" (no change) Parameters:oldChar - the old character.newChar - the new character. Returns:a string derived from this string by replacing every occurrence of oldChar with newChar.
