vue 中 js 金额数字转中文

参考:js工具函数之数字转为中文数字和大写金额_js封装工具类函数金额大写-CSDN博客

我使用的框架vol.core。 客户需求要将录入框的金额数字转换成中文在旁边显示,换了几种函数,最终确定如下函数

function changeToChineseMoney(Num) {
  //判断如果传递进来的不是字符的话转换为字符
  if (typeof Num == "number") {
    Num = new String(Num);
  };
  Num = Num.replace(/,/g, "") //替换tomoney()中的","
  Num = Num.replace(/ /g, "") //替换tomoney()中的空格
  Num = Num.replace(/¥/g, "") //替换掉可能出现的¥字符
  if (isNaN(Num)) { //验证输入的字符是否为数字
    //alert("请检查小写金额是否正确");
    return "";
  };
  //字符处理完毕后开始转换,采用前后两部分分别转换
  var part = String(Num).split(".");
  var newchar = "";
  //小数点前进行转化
  for (var i = part[0].length - 1; i >= 0; i--) {
    if (part[0].length > 10) {
      return "";
      //若数量超过拾亿单位,提示
    }
    var tmpnewchar = ""
    var perchar = part[0].charAt(i);
    switch (perchar) {
      case "0":
        tmpnewchar = "零" + tmpnewchar;
        break;
      case "1":
        tmpnewchar = "壹" + tmpnewchar;
        break;
      case "2":
        tmpnewchar = "贰" + tmpnewchar;
        break;
      case "3":
        tmpnewchar = "叁" + tmpnewchar;
        break;
      case "4":
        tmpnewchar = "肆" + tmpnewchar;
        break;
      case "5":
        tmpnewchar = "伍" + tmpnewchar;
        break;
      case "6":
        tmpnewchar = "陆" + tmpnewchar;
        break;
      case "7":
        tmpnewchar = "柒" + tmpnewchar;
        break;
      case "8":
        tmpnewchar = "捌" + tmpnewchar;
        break;
      case "9":
        tmpnewchar = "玖" + tmpnewchar;
        break;
    }
    switch (part[0].length - i - 1) {
      case 0:
        tmpnewchar = tmpnewchar + "元";
        break;
      case 1:
        if (perchar != 0) tmpnewchar = tmpnewchar + "拾";
        break;
      case 2:
        if (perchar != 0) tmpnewchar = tmpnewchar + "佰";
        break;
      case 3:
        if (perchar != 0) tmpnewchar = tmpnewchar + "仟";
        break;
      case 4:
        tmpnewchar = tmpnewchar + "万";
        break;
      case 5:
        if (perchar != 0) tmpnewchar = tmpnewchar + "拾";
        break;
      case 6:
        if (perchar != 0) tmpnewchar = tmpnewchar + "佰";
        break;
      case 7:
        if (perchar != 0) tmpnewchar = tmpnewchar + "仟";
        break;
      case 8:
        tmpnewchar = tmpnewchar + "亿";
        break;
      case 9:
        tmpnewchar = tmpnewchar + "拾";
        break;
    }
    var newchar = tmpnewchar + newchar;
  }
  //小数点之后进行转化
  if (Num.indexOf(".") != -1) {
    if (part[1].length > 2) {
      // alert("小数点之后只能保留两位,系统将自动截断");
      part[1] = part[1].substr(0, 2)
    }
    for (i = 0; i < part[1].length; i++) {
      tmpnewchar = ""
      perchar = part[1].charAt(i)
      switch (perchar) {
        case "0":
          tmpnewchar = "零" + tmpnewchar;
          break;
        case "1":
          tmpnewchar = "壹" + tmpnewchar;
          break;
        case "2":
          tmpnewchar = "贰" + tmpnewchar;
          break;
        case "3":
          tmpnewchar = "叁" + tmpnewchar;
          break;
        case "4":
          tmpnewchar = "肆" + tmpnewchar;
          break;
        case "5":
          tmpnewchar = "伍" + tmpnewchar;
          break;
        case "6":
          tmpnewchar = "陆" + tmpnewchar;
          break;
        case "7":
          tmpnewchar = "柒" + tmpnewchar;
          break;
        case "8":
          tmpnewchar = "捌" + tmpnewchar;
          break;
        case "9":
          tmpnewchar = "玖" + tmpnewchar;
          break;
      }
      if (i == 0) tmpnewchar = tmpnewchar + "角";
      if (i == 1) tmpnewchar = tmpnewchar + "分";
      newchar = newchar + tmpnewchar;
    }
  }
  //替换所有无用汉字
  while (newchar.search("零零") != -1)
    newchar = newchar.replace("零零", "零");
  newchar = newchar.replace("零亿", "亿");
  newchar = newchar.replace("亿万", "亿");
  newchar = newchar.replace("零万", "万");
  newchar = newchar.replace("零元", "元");
  newchar = newchar.replace("零角", "");
  newchar = newchar.replace("零分", "");
  if (newchar.charAt(newchar.length - 1) == "元") {
    newchar = newchar + "整"
  }
  return newchar;
}

在公共函数库文件common.js中增加一个函数changeToChineseMoney,然后到页面代码中调用。

实际代码效果图如下
