思路:
- 数字 => 字符串
- 字符串对应数字 => 汉字 (特别要注意此处插入顺序跟正常正好相反, 要倒序处理)
- 汉字中插入数值单位(万/千/百 …)
- 对连续了零进行处理
handleNumberToChinese = (num) =>{
let arr1 = ['零', '一', '二', '三', '四', '五', '六', '七', '八', '九'];
let arr2 = ['', '十', '百', '千', '万', '十', '百', '千', '亿', '十', '百', '千','万'];
var arr = num;
let newArr = arr.toString().split('');
console.log(newArr);
let result = '';
for(let i = 0 ; i < newArr.length ; i++ ){
result = arr2[i] + result;
let reverse = newArr.length - i -1; //倒序处理
let arr1_index = newArr[reverse];
result = arr1[arr1_index] + result;
}
result = result.replace(/零(千|百|十)/g, '零').replace(/十零/g, '十');
result = result.replace(/零+/g, '零');
result = result.replace(/零亿/g, '亿').replace(/零万/g, '万');
result = result.replace(/亿万/g, '亿');
result = result.replace(/零+$/, '');
result = result.replace(/^一十/g, '十');
return result;
}
