在做财务相关功能时,经常需要用到JavaScript将数字转换成大写中文,这些提供个详情的方法给大家。
//************************* 把数字金额转换成中文大写数字的函数(可处理负值) *********************************// function changeNumMoneyToChinese(money) { var cnNums = new Array("零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"); //汉字的数字 var cnIntRadice = new Array("", "拾", "佰", "仟"); //基本单位 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 var Symbol="";//正负值标记 if (money == "") { return ""; } money = parseFloat(money); if (money >= maxNum) { alert('超出最大处理数字'); return ""; } if (money == 0) { ChineseStr = cnNums[0] + cnIntLast + cnInteger; return ChineseStr; } if(money<0) { money=-money; Symbol="负 "; } money = money.toString(); //转换为字符串 if (money.indexOf(".") == -1) { IntegerNum = money; DecimalNum = ''; } else { parts = money.split("."); IntegerNum = parts[0]; DecimalNum = parts[1].substr(0, 4); } if (parseInt(IntegerNum, 10) > 0) { //获取整型部分转换 var zeroCount = 0; var IntLen = IntegerNum.length; for (var i = 0; i < IntLen; i++) { var n = IntegerNum.substr(i, 1); var p = IntLen - i - 1; var q = p / 4; var m = p % 4; if (n == "0") { zeroCount++; } else { if (zeroCount > 0) { ChineseStr += cnNums[0]; } zeroCount = 0; //归零 ChineseStr += cnNums[parseInt(n)] + cnIntRadice[m]; } if (m == 0 && zeroCount < 4) { ChineseStr += cnIntUnits[q]; } } ChineseStr += cnIntLast; //整型部分处理完毕 } if (DecimalNum != '') { //小数部分 var decLen = DecimalNum.length; for (var i = 0; i < decLen; i++) { var n = DecimalNum.substr(i, 1); if (n != '0') { ChineseStr += cnNums[Number(n)] + cnDecUnits[i]; } } } if (ChineseStr == '') { ChineseStr += cnNums[0] + cnIntLast + cnInteger; } else if (DecimalNum == '') { ChineseStr += cnInteger; } ChineseStr = Symbol +ChineseStr; return ChineseStr; } console.log(changeNumMoneyToChinese(235962.22))
