Vue—将数字转换为大写金额

一、template

                <el-input
                  type="number"
                  v-enter-number=""
                  v-model="value"
                  placeholder="请输入金额"
                ></el-input>
              <p>
                <span>大写：</span
                ><span>{{ smallToBig(value) }}</span>
              </p>

二、script

data(){
	return {
		value:''
	}
},
methods:{
	smallToBig(money) {
      //  将数字金额转换为大写金额
      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"; //整数完以后的单位
      //最大处理的数字
      var maxNum = 999999999999999.9999;
      var integerNum; //金额整数部分
      var decimalNum; //金额小数部分
      //输出的中文金额字符串
      var chineseStr = "";
      var parts; //分离金额后用的数组，预定义
      if (money == "") {
        return "";
      }

      money = parseFloat(money);
      if (money >= maxNum) {
        //超出最大处理数字
        return "超出最大处理数字";
      }
      if (money == 0) {
        chineseStr = cnNums[0] + cnIntLast + cnInteger;
        return chineseStr;
      }

      //四舍五入保留两位小数,转换为字符串
      money = Math.round(money * 100).toString();
      integerNum = money.substr(0, money.length - 2);
      decimalNum = money.substr(money.length - 2);

      //获取整型部分转换
      if (parseInt(integerNum, 10) > 0) {
        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];
            }
            //归零
            zeroCount = 0;
            chineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
          }
          if (m == 0 && zeroCount < 4) {
            chineseStr += cnIntUnits[q];
          }
        }
        chineseStr += cnIntLast;
      }
      //小数部分
      if (decimalNum != "") {
        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 == "" || /^0*$/.test(decimalNum)) {
        chineseStr += cnInteger;
      }
      return chineseStr;
    }
}
