我是靠谱客的博主活力飞机，最近开发中收集的这篇文章主要介绍JS案例分享之金额小写转大写，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

之前做项目的时候遇到需要在输入小写金额之后自动转成大写，经过一番研究，整出了如下代码，分享给大家，希望有所帮助

复制代码代码如下:

function Arabia_to_Chinese(Num){ 
for(i=Num.length-1;i>=0;i--) 
{ 
Num = Num.replace(",","") 
Num = Num.replace(" ","") 
} 
Num = Num.replace("￥","") 
if(isNaN(Num)) { 
alert("请检查小写金额是否正确"); 
return; 
} 
part = String(Num).split("."); 
newchar = ""; 
for(i=part[0].length-1;i>=0;i--){ 
if(part[0].length > 10){ alert("位数过大，无法计算");return "";} 
tmpnewchar = "" 
perchar = part[0].charAt(i); 
switch(perchar){ 
case "0": tmpnewchar="零" + tmpnewchar ;break; 
case "1": tmpnewchar="壹" + tmpnewchar ;break; 
case "2": tmpnewchar="贰" + tmpnewchar ;break; 
case "3": tmpnewchar="叁" + tmpnewchar ;break; 
case "4": tmpnewchar="肆" + tmpnewchar ;break; 
case "5": tmpnewchar="伍" + tmpnewchar ;break; 
case "6": tmpnewchar="陆" + tmpnewchar ;break; 
case "7": tmpnewchar="柒" + tmpnewchar ;break; 
case "8": tmpnewchar="捌" + tmpnewchar ;break; 
case "9": tmpnewchar="玖" + tmpnewchar ;break; 
} 
switch(part[0].length-i-1){ 
case 0: tmpnewchar = tmpnewchar +"元" ;break; 
case 1: if(perchar!=0)tmpnewchar= tmpnewchar +"拾" ;break; 
case 2: if(perchar!=0)tmpnewchar= tmpnewchar +"佰" ;break; 
case 3: if(perchar!=0)tmpnewchar= tmpnewchar +"仟" ;break; 
case 4: tmpnewchar= tmpnewchar +"万" ;break; 
case 5: if(perchar!=0)tmpnewchar= tmpnewchar +"拾" ;break; 
case 6: if(perchar!=0)tmpnewchar= tmpnewchar +"佰" ;break; 
case 7: if(perchar!=0)tmpnewchar= tmpnewchar +"仟" ;break; 
case 8: tmpnewchar= tmpnewchar +"亿" ;break; 
case 9: tmpnewchar= tmpnewchar +"拾" ;break; 
} 
newchar = tmpnewchar + newchar; 
} 
if(Num.indexOf(".")!=-1){ 
if(part[1].length > 2) { 
part[1] = part[1].substr(0,2) 
} 
for(i=0;i<part[1].length;i++){ 
tmpnewchar = "" 
perchar = part[1].charAt(i) 
switch(perchar){ 
case "0": tmpnewchar="零" + tmpnewchar ;break; 
case "1": tmpnewchar="壹" + tmpnewchar ;break; 
case "2": tmpnewchar="贰" + tmpnewchar ;break; 
case "3": tmpnewchar="叁" + tmpnewchar ;break; 
case "4": tmpnewchar="肆" + tmpnewchar ;break; 
case "5": tmpnewchar="伍" + tmpnewchar ;break; 
case "6": tmpnewchar="陆" + tmpnewchar ;break; 
case "7": tmpnewchar="柒" + tmpnewchar ;break; 
case "8": tmpnewchar="捌" + tmpnewchar ;break; 
case "9": tmpnewchar="玖" + tmpnewchar ;break; 
} 
if(i==0)tmpnewchar =tmpnewchar + "角"; 
if(i==1)tmpnewchar = tmpnewchar + "分"; 
newchar = newchar + tmpnewchar; 
} 
} 
while(newchar.search("零零") != -1) 
newchar = newchar.replace("零零", "零"); 
newchar = newchar.replace("零亿", "亿"); 
newchar = newchar.replace("亿万", "亿"); 
newchar = newchar.replace("零万", "万"); 
newchar = newchar.replace("零元", "元"); 
newchar = newchar.replace("零角", ""); 
newchar = newchar.replace("零分", ""); 
if (newchar.charAt(newchar.length-1) == "元" || newchar.charAt(newchar.length-1) == "角") 
newchar = newchar+"整" 
return newchar; 
}
