　　網(LieHuo.Net)教程本教程介紹的知識可以將數字翻譯成英語的JavaScript，可以自動判斷出你輸入的數字是多大，它會自動拼合，按億、千萬、百萬的語法翻譯出來，挺實用。

<html><head><title>數字轉換成英文的JavaScript - 網LIEHUO.NET - 關注站長，建設互聯網！</title><script>var arr1=new Array(""," thousand"," million"," billion")var arr2=new Array("zero","ten","twenty","thirty","forty","fifty","sixty","seventy","eighty","ninety")var arr3=new Array("zero","one","two","three","four","five","six","sever","eight","nine");var arr4=new Array("ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen");function Translate(num){ var len=num.length,i,j=0,strRet=""; var cols=Math.ceil(len/3); var first=len-cols*3 var strRet="" for(i=first;i<len;i+=3){ ++j; if(i>=0) num3=num.substring(i,i+3) else num3=num.substring(0,first+3) strEng=English(num3) if(strEng!=""){ if(strRet!="") strRet+="," strRet+=English(num3)+arr1[cols-j] } } return strRet}function English(num){ strRet="" if((num.length==3) && (num.substr(0,3)!="000")){ if((num.substr(0,1)!="0")){ strRet+=arr3[num.substr(0,1)]+" hundred" if(num.substr(1,2)!="00")strRet+=" and " } num=num.substring(1); } if((num.length==2)){ if((num.substr(0,1)=="0")){ num=num.substring(1) } else if((num.substr(0,1)=="1")){ strRet+=arr4[num.substr(1,2)] } else{ strRet+=arr2[num.substr(0,1)] if(num.substr(1,1)!="0")strRet+="-" num=num.substring(1) } } if((num.length==1) && (num.substr(0,1)!="0")){ strRet+=arr3[num.substr(0,1)] } return strRet;}</script></head><body><input id=number value=654321><input type=button title="網LIEHUO.NET - 關注站長，建設互聯網！" value=翻譯 onclick=alert(Translate(document.all.number.value))></body></html>
