password restrictions

Ssanai80 · Jul 9, 2001

I am making a asp page where my client can request for an id and password. on the requestform, i want to ensure that the client requests a password that has at least one numeric, one upper case, and one lower case characters. How can i use javascript to alert when requested pwd submitted did not meet above requirements?
i thought about converting the input to all caps than match it with original...then samething but convert to small caps...and if there is a match in either case, alert. would that work? and how do i convert input string to caps? or small caps? and how do i check for at least one numeric character?
thank you in advance for all da help

I think this will work:

Code:

<html>
<head>
<script>
function check() {
var pw = document.forms[0].pw.value
if (pw.toUpperCase() == pw || pw.toLowerCase() == pw) {
alert(&quot;Field must contain an uppercase and lowercase character.&quot;)
return false
}
if (!(/\d/.test(pw))) {
alert(&quot;Field must contain a number.&quot;)
return false
}
else {
return true
}
}
</script>
</head>
<body>
<form onsubmit=&quot;return check()&quot;>
<input type=&quot;password&quot; name=&quot;pw&quot; />
<input type=&quot;submit&quot; value=&quot;Submit&quot; />
</form>
</body>
</html>

thank you very much!! your code worked great!
but why "document.forms(0)"?? i didn't understand that part.
since my form was called "requestform" and the input name was "password", shouldn't requestform.password.value work?
where did "document" or "forms(0)" come from?

forms[0] (square brackets, not parens) refers to the first form in the document. You could also have used document.requestform.password.value
I think he used forms[0] because he wasn't sure if requestform was the name of the form or just a description of it. Tracy Dryden
