Error in script - testing if a field has a non character

[Denize]

I am creating a script that may check if a field has a non character and if yes it may appears an error message after I move to the next field.

When I use this script in PL/SQL (...v_enabled|| ' onBlur ="chkString(thi s)"')
I receive the error: runtime error, object expected.
Can you tell me why this error is happening, please?

geralp.p('<scri pt language="JavaS cript">
function chkstring(p_cam po)
{
var value = (p_campo.value) .toUppercase();
var letras = ''AÁÀÃÂÄBCÇDEÉÈ ÊËFGHIÍÌÎÏJKLMN OÓÒÔÖPQRSTUÚÙÛÜ VWXYÝZ '';

for(i=0;i<value .length;i++)
{
var carct=value.cha rAt(i);

if(letras.index Of(carct)==-1)
{
alert(''teste: ''+carct);
p_campo.value=" ";
p_campo.focus() ;
return false;
}

}

return true;
}
</script>
'
);



Thanks,

By non-character, you mean anything besides the characters in the 'letras' string?

Exactly. I have a field in a form that can accept only the characters in the string letras.

Thanks in advance,

Then you should use regular expressions - see link.
