JS realizes the conversion of RMB capital amount form_javascript skills

The example in this article shares with you the relevant js code to convert the amount to uppercase for your reference. The specific content is as follows

function convertCurrency(num) { //转成人民币大写金额形式
  var str1 = '零壹贰叁肆伍陆柒捌玖'; //0-9所对应的汉字
  var str2 = '万仟佰拾亿仟佰拾万仟佰拾元角分'; //数字位所对应的汉字
  var str3; //从原num值中取出的值
  var str4; //数字的字符串形式
  var str5 = ''; //人民币大写金额形式
  var i; //循环变量
  var j; //num的值乘以100的字符串长度
  var ch1; //数字的汉语读法
  var ch2; //数字位的汉字读法
  var nzero = 0; //用来计算连续的零值是几个
  num = Math.abs(num).toFixed(2); //将num取绝对值并四舍五入取2位小数
  str4 = (num * 100).toFixed(0).toString(); //将num乘100并转换成字符串形式
  j = str4.length; //找出最高位
  if (j > 15) {
    return '溢出';
  }
  str2 = str2.substr(15 - j); //取出对应位数的str2的值。如：200.55,j为5所以str2=佰拾元角分
  //循环取出每一位需要转换的值
  for (i = 0; i str3 = str4.substr(i, 1); //取出需转换的某一位的值
    if (i != (j - 3) && i != (j - 7) && i != (j - 11) && i != (j - 15)) { //当所取位数不为元、万、亿、万亿上的数字时
      if (str3 == '0') {
        ch1 = '';
        ch2 = '';
        nzero = nzero + 1;
      } else {
        if (str3 != '0' && nzero != 0) {
          ch1 = '零' + str1.substr(str3 * 1, 1);
          ch2 = str2.substr(i, 1);
          nzero = 0;
        } else {
          ch1 = str1.substr(str3 * 1, 1);
          ch2 = str2.substr(i, 1);
          nzero = 0;
        }
      }
    } else { //该位是万亿，亿，万，元位等关键位
      if (str3 != '0' && nzero != 0) {
        ch1 = "零" + str1.substr(str3 * 1, 1);
        ch2 = str2.substr(i, 1);
        nzero = 0;
      } else {
        if (str3 != '0' && nzero == 0) {
          ch1 = str1.substr(str3 * 1, 1);
          ch2 = str2.substr(i, 1);
          nzero = 0;
        } else {
          if (str3 == '0' && nzero >= 3) {
            ch1 = '';
            ch2 = '';
            nzero = nzero + 1;
          } else {
            if (j >= 11) {
              ch1 = '';
              nzero = nzero + 1;
            } else {
              ch1 = '';
              ch2 = str2.substr(i, 1);
              nzero = nzero + 1;
            }
          }
        }
      }
    } if (i == (j - 11) || i == (j - 3)) { //如果该位是亿位或元位，则必须写上
      ch2 = str2.substr(i, 1);
    }
    str5 = str5 + ch1 + ch2;
    if (i == j - 1 && str3 == '0') { //最后一位（分）为0时，加上“整”
      str5 = str5 + '整';
    }
  }
  if (num == 0) {
    str5 = '零元整';
  }
  if (str5.indexOf("分") == -1) {
    if (str5.indexOf("拾元零") > 0) {
      str5 = str5.replace("拾元零", "拾元");
    };
  }
  return str5;
}
 
function doConvert(m, n) {
  Ext.getCmp(m).on('change', function() {
    var objm = Ext.getCmp(m);
    var objn = Ext.getCmp(n);
    if (!(/^\d+(\.\d+)?$/.test(objm.getValue()))) {
      objn.setValue("");
    } else {
      var money = convertCurrency(objm.getValue());
      if (objm.getValue() == "") {
        objn.setValue("");
      } else {
        objn.setValue(money);
      }
    }
    var money = convertCurrency(objm.getValue());
    if (money.indexOf("拾元零") > 0) {
      if (money.indexOf("分") == -1) {
        objn.setValue(money.replace("拾元零", "拾元"));
      }
    };
  });
}
