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"));
      }
    };
  });
}
