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;

}
