将数字转换成大写的人民币表达式的js函数_javascript技巧

将数字转换成大写的人民币，方法有很多，本例介绍的是使用js来完成的，看看下面的实现代码

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 ""; } 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; } 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; } return ChineseStr; }
