I would like to ask you the following:
I use Macromedia Dreamweaver as an editor for HTML and Js.
It also writes some js functions to simply validate forms.
I always used it with no bugs.
Till now. This is the problem (and the page):

d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++)
x=d.forms[i][n];

x=MM_findObj(n,d.layers[i].document);

function MM_validateForm() { //v4.0
var i,p,q,nm,test,num,min,max,errors='',args=MM_valida teForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2];
val=MM_findObj(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an
e-mail address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' must contain a
number between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is
required.\n'; }
} if (errors) alert('The following error(s) occurred:\n'+errors);
document.MM_returnValue = (errors == '');
}

<body>
<form name="formA">
<input type="text" name="pippo">
<input type="text" name="email">
<input name="A" type="submit"
onClick="MM_validateForm('pippo','','R','email','' ,'RisEmail');return
document.MM_returnValue" value="Invia">
</form>
<form name="formB">
<input type="hidden" name="pippo">
<input type="hidden" name="email">
</form>
</body>
</html>
================================================== =========================
My target is to validate "pippo" to have it not empty and "email" not
empty but also a valid email.
Dreamweaver wrote these 2 functions to do this and added onClick event
to button this way.
The only new thing I did is to write an hidden form with same fields
names because I have to do this before posting data.
I tried this code in Firefox and it works fine.
I tried this in IE and it says: "'val' is null or it is not an object".
What do you think about it?
Any help much appreciated.
Regards.
