Js实现数字转化人名币汉字

实现将阿拉伯数字转变成汉字计数

function changeNumMoneyToChinese(money) {

	  var cnIntUnits = new Array("", "万", "亿", "兆"); //对应整数部分扩展单位
	  var cnDecUnits = new Array("角", "分", "毫", "厘"); //对应小数部分单位
	  var cnInteger = "整"; //整数金额时后面跟的字符
	  var cnIntLast = "元"; //整型完以后的单位
	  var maxNum = 999999999999999.9999; //最大处理的数字
	  var IntegerNum; //金额整数部分
	  var DecimalNum; //金额小数部分
	  var ChineseStr = ""; //输出的中文金额字符串
	  var parts; //分离金额后用的数组，预定义
	  if (money == "") {
	    return "";
	  }
