求助! 这个程序好像没调用.

<html> <head> <title>order from example</title> <script language="javascript"> <!-- hide this script from non-javascript-enbled browsers function isANumber(inputvalue){ var result=true if(! parseFloat(inputvalue){ result=false } else{ for(var i=0;i<=inputvalue.length;i++) if(inputvalue.charAt(i)=" "){ if(! parseFloat(inputvalue.charAt(i))){ result=false break } } } }

return result }

function isAvalidE-mail(inputvalue){ var foundAt=flase var foundDot=false for(var i=0;i<=inputvalue.length;i++){ if(inputvalue.charAt(i)=="@"){ foundAt=true } } if(foundAt&&foundDot){ return true } else { return false } }

function isAvalidPhoneNumber(inputvalue){ var digitsfound=0 for(var i=0;i<=inputvalue.length;i++){ if(isANumber(inptvalue.charAt(i))){ digitsfound++ } } if(digitsfound>=10){ return true } else{ return false} }

function exists(inputvalue){ var aCharExists=false for(var i=0;i<=inputvalue.length;i++){

if(inputvalue.chatAt(i)!=" " && inputvalue.chatAt(i)!= ""){ aCharExists=true break } } return aCharExists }

function validateform(){ var rc=true if(!document.quoteForm.designChoice.checked&& !document.quoteForm.mainChoice.checked&& !document.quoteForm.promoChoice.checked){ alert("please check whether yuou're interested in our design,maintenancem, or promotion services so we can give you a more accurate quote. thanks!") rc=false }

就是在上面<head>和</head>中的函数,在<body></body>中没调用, 无任何结果.
