如题,分享一个自用的阿拉伯数字金额转成中文大写,支持负数,单位元,小数支持4位数(角、分、毫、厘)
不是我写的,网上抄来的,稍加修改,已用在项目中,亲测可用。
上硬货代码
//测试 console.log(moneyNumToChinese(-3.14)); // 负 叁元壹角肆分 console.log(moneyNumToChinese(10002)); // 壹万零贰元整 //***************** 把阿拉伯数字金额转换成中文大写数字的函数(可处理负值,小数可精确到4位厘,) *************************// function moneyNumToChinese(money) { if (money == undefined || money == null || money == "") { return ""; } 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 pmSymbol = ""; //正负值标记 money = parseFloat(money); if (money > maxNum || 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; pmSymbol = "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 = pmSymbol + chineseStr; return chineseStr; }
