js工具函数之数字转为中文数字和大写金额

1. 数字转为中文数字

function numberToChinese(num) {var AA = new Array("零", "一", "二", "三", "四", "五", "六", "七", "八", "九", "十");var BB = new Array("", "十", "百", "仟", "萬", "億", "点", "");var a = ("" + num).replace(/(^0*)/g, "").split("."),k = 0,re = "";for (var i = a[0].length - 1; i >= 0; i--) {switch (k) {case 0:re = BB[7] + re;break;case 4:if (!new RegExp("0{4}//d{" + (a[0].length - i - 1) + "}$").test(a[0]))re = BB[4] + re;break;case 8:re = BB[5] + re;BB[7] = BB[5];k = 0;break;}if (k % 4 == 2 && a[0].charAt(i + 2) != 0 && a[0].charAt(i + 1) == 0)re = AA[0] + re;if (a[0].charAt(i) != 0)re = AA[a[0].charAt(i)] + BB[k % 4] + re;k++;}if (a.length > 1) // 加上小数部分(如果有小数部分){re += BB[6];for (var i = 0; i < a[1].length; i++)re += AA[a[1].charAt(i)];}if (re == '一十')re = "十";if (re.match(/^一/) && re.length == 3)re = re.replace("一", "");return re;
}
let numTem = 1545644;
console.log(numberToChinese(numTem));  // 一百五十四萬五仟六百四十四
