Shouldn't this test to see how long their password is? It doens't do anything! Even if I take out the first emptyValidation part.

function formValidation(PasswordForm)
{
with (PasswordForm)
{
if (emptyValidation(txtPassword, "Please enter a password.") == false)
{
txtPassword.focus();
return false;
}
if (txtPassword.length < 6)
{
alert('Your password must be at least 6 characters long.')
}
if (emptyValidation(ConfirmPassword, &quot;Please enter a confirmation password.&quot;) == false)
{
ConfirmPassword.focus();
return false;
}
}
}

well, I dont really understand your code, especially with
Code: 
emptyValidation()
in there, but try this:

add this line right after the { of you function declaration:

txtPassword=document.formName.txtPassword;

where formName is the name of the form where the password box lies. Robert Carpenter

The emptyValidation is there because I have a function which checks to see if fields are empty (I didn't post ALL of my code on here, I could if that would help).

I changed it to this and it doesn't make a difference.

function formValidation(PasswordForm)
{
txtPassword=document.PasswordForm.txtPassword;

with (PasswordForm)
{
if (emptyValidation(txtPassword, &quot;Please enter a password.&quot;) == false)
{
txtPassword.focus();
return false;
}
if (txtPassword.length < 6)
{
alert('Your password must be at least 6 characters long.')
}
if (emptyValidation(ConfirmPassword, &quot;Please enter a confirmation password.&quot;) == false)
{
ConfirmPassword.focus();
return false;
}
}
}

you might try that. I think the problem could actually be in your emptyValidation code

Oh no! Here's the code for that.

function emptyValidation(entered, alertbox)
{
with (entered)
{
if (value == null || value == &quot;&quot;)
{
if (alertbox!=&quot;&quot;)
{
alert(alertbox);
}
return false;
}
else
{
return true;
}
}
}

ok, well, I dont know what your problem is, it works fine for me. here is the whole html page i used.

Code: 
<html>
<head>
<title></title>
<script language=javascript>
function emptyValidation(entered, alertbox)
{
    with (entered)
    {
        if (value == null || value == &quot;&quot;)
        {
            if (alertbox!=&quot;&quot;) 
            {
                alert(alertbox);
            } 
            return false;
        }
        else 
        {
            return true;
        }
    }    
}

function formValidation(PasswordForm)
{
    //txtPassword=document.PasswordForm.txtPassword;
    
    with (PasswordForm)
    {
        if (emptyValidation(txtPassword, &quot;Please enter a password.&quot;) == false) 
        {
            txtPassword.focus(); 
            return false;
        }
        if (txtPassword.length < 6)
        {
            alert('Your password must be at least 6 characters long.')
        }
        if (emptyValidation(ConfirmPassword, &quot;Please enter a confirmation password.&quot;) == false) 
        {
            ConfirmPassword.focus(); 
            return false;
        }                
    }
}
</script>
</head>
<body>

<form name=&quot;PasswordForm&quot;>
<input type=password name=txtPassword><input type=password name=ConfirmPassword><input type=button onClick=formValidation(this.form)>
</form>

</body>
</html>

actually, I just had a thought, its probably in your function call

make sure that it passes a form as a value, not an input.

see above Robert Carpenter

Ok...It's still not bringing up the prompt. I'm sorry, I am clueless, and don't even enjoy doing this stuff, so I'm sure I am annoying you like crazy.

Here is all of my javascript:



<SCRIPT language=&quot;JavaScript&quot;>

function NewCompany()
{
var NewCompany= prompt('New Company name:', ' ');

if ( (NewCompany==' ') || (NewCompany==null) )
{
NewCompany=&quot;Null&quot;;
}
}

function NewPlan()
{
var NewPlan= prompt('New Plan name:', ' ');

if ( (NewPlan==' ') || (NewPlan==null) )
{
NewPlan=&quot;Null&quot;;
}
}

function AskDelete()
{
var AskDelete= confirm('Are you sure you want to delete this company?', ' ');
}

function emptyValidation(entered, alertbox)
{
with (entered)
{
if (value == null || value == &quot;&quot;)
{
if (alertbox!=&quot;&quot;)
{
alert(alertbox);
}
return false;
}
else
{
return true;
}
}
}


function formValidation(CompanyName)
{
with (CompanyName)
{
if (emptyValidation(CompanyName, &quot;Please enter a Company Name.&quot;) == false)
{
CompanyName.focus();
return false;
}
}
}

function formValidation(PasswordForm)
{
//txtPassword=document.PasswordForm.txtPassword;

with (PasswordForm)
{
if (emptyValidation(txtPassword, &quot;Please enter a password.&quot;) == false)
{
txtPassword.focus();
return false;
}
if (txtPassword.length < 6)
{
alert('Your password must be at least 6 characters long.')
}
if (emptyValidation(ConfirmPassword, &quot;Please enter a confirmation password.&quot;) == false)
{
ConfirmPassword.focus();
return false;
}
}
}

</SCRIPT>

and here is the form code:



<form id=form1 name=PasswordForm onSubmit=&quot;return(formValidation(PasswordForm))&quot;>
<tr>
<td>
<font face=arial,tahoma size=2 color=#000000>
Password:&nbsp;
</td>
<td>
<input type=password size=12 maxlength=255 name=txtPassword>
</td>
</tr>
<tr>
<td>
<font face=arial,tahoma size=2 color=#000000>
Confirm Password:&nbsp;
</td>
<td>
<input type=password size=12 maxlength=255 name=ConfirmPassword>
</td>
</tr>
<tr>
<td colspan=2 align=right>
<input type=button value=&quot;Apply Change&quot; onClick=formValidation(this.form)>
</td>
</tr>
</form>

Nope!

I don't see why it won't work. You know - even if I take out all of the password stuff and just make it

function formValidation(PasswordForm)
{
//txtPassword=document.PasswordForm.txtPassword;

with (PasswordForm)
{
if (txtPassword.length < 6)
{
alert('Your password must be at least 6 characters long.')
}
}
}

...it still doesn't detect that there are less than 6 characters. Very, very strange...

function formValidation(CompanyName){}
function formValidation(PasswordForm){}

CompanyName fuction gets overwritten by PasswordForm function. Try different names.



I think I may have your solution:

Change if (txtPassword.length < 6) in your formValidation function to if (txtPassword.value.length < 6)

Oddly enough, I think it was checking the txtPassword object, which for some reason was undefined, as opposed to it's length. &quot;The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us&quot;

I'm still having the problem that I posted in the other thread, but this one is fixed. I'll deal with the other after lunch ;)

It would work on my system, just not check the value correctly. Without the .value added in, it was returning &quot;undefined&quot;, so it wasn't triggering the if statement. &quot;The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us&quot;
