js實現阿拉伯數字和中文數字互相轉換

阿拉伯數字轉中文數字

// 節內轉換算法 function SectionToChinese(section){ var strIns = '', chnStr = ''; var unitPos = 0; var zero = true; while(section > 0){ var v = section % 10; if(v === 0){ if(!zero){ zero = true; chnStr = chnNumChar[v] + chnStr; } }else{ zero = false; strIns = chnNumChar[v]; strIns += chnUnitChar[unitPos]; chnStr = strIns + chnStr; } unitPos++; section = Math.floor(section / 10); } return chnStr; } // 轉換算法主函數 function NumberToChinese(num){ var unitPos = 0; var strIns = '', chnStr = ''; var needZero = false; if(num === 0){ return chnNumChar[0]; } while(num > 0){ var section = num % 10000; if(needZero){ chnStr = chnNumChar[0] + chnStr; } strIns = SectionToChinese(section); strIns += (section !== 0) ? chnUnitSection[unitPos] : chnUnitSection[0]; chnStr = strIns + chnStr; needZero = (section < 1000) && (section > 0); num = Math.floor(num / 10000); unitPos++; } return chnStr; }
