Convert a vb function to javascript function... 1

petersmith · Jul 7, 2005

Hi i have this working vb function which i need to call on an onclick event in javascript...

function ValKey(Vin)
dim k, i, s, b
k= ""

if len(Vin) = 7 then
s = UCase(mid(Vin,1,1))
if s = "A" or s = "S" or s = "M" then
b = true
for i = 2 to 7
if not IsNumeric(mid(Vin,i,1)) then b = false
next
if b then k = ucase(Vin)
end if
end if
Valkey = k
end function

can anyone show me how to convert it or get it to work on an onclick event?

kindest thanks.

If using IE only, you do not need to convert it. You can call the VBScript function directly from the onclick event.

Or do you need it to work cross-browser?

How about this (using regular expressions):

Code:

<html><head><title></title>
<script type="text/javascript">
function valKey(_myKey){
  return (/[AaMmSs]{1}[0123456789]{7}/g.test(_myKey));
}
</script>
</head>
<body>
<form name="myTestForm" action="">
<input type="text" name="keyField" value="A1234567" onchange="alert(valKey(this.value))">
<input type="button" value="Test" onclick="alert(valKey(forms[0].elements['keyField'].value));">
</form>
</body>
</html>

I have added an onclick for a button and an onchange to the input element to allow you to test it.

Hope this does all you want [smile]

Ah... looking at your code you wanted 6 digits... my code requires 7 digits. Make this change:

Code:

return (/[AaMmSs]{1}[0123456789]{[COLOR=red]6[/color]}/g.test(_myKey));

Cheers,
Jeff

Thanks, this works. How would you get it to display false if there are more than 6 digits and display an alert saying "incorect format" or somthing?

kindest thanks.

Hi i have tried to call this function on an onclick event but it doesn't work..

<script type="text/javascript">
function valKey(){
var Key

Key = document.form1.minvin.value;

if (/[AaMmSs]{1}[0123456789]{6}/g.test(Key)) == true {
document.form1.form.submit ;
else
alert("Vin format is incorrect (e.g. A123456)\nPlease try again.")
}
}
</script>

Any ideas where i have gone wrong?

kindest thanks.

Something like this will kind of do it:

Code:

<script type="text/javascript">
function valKey(_myKey){
  var bValid = /[AaMmSs]{1}[0123456789]{7}/g.test(_myKey);
  if (!bValid) errMsg += '\nIncorrect format. Use A, M, S followed by exactly 6 digits. Example: A123456';
  return bValid;
}
</script>

Cheers,
Jeff
