Perl File snippet:
<SCRIPT LANGUAGE="JavaScript" SRC="/js_validation/js.js"></SCRIPT>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+">
</head>

<body>
<form onsubmit="return formValidator()">
<table>
<tr><td>
Test Field: <input type="text" value="--" size="2" maxlength="2" id="p
+lace"><br></td>
</tr>
<input type='submit' value='Check Form'><br>

Javascript:
/* SOURCE FILE: form_validation.js */

function formValidator(){
        var place = document.getElementById("place");
                    
        if(isNumeric(place, "Please enter a valid zip code")){
            return true;
        }

    return false;
    
}

function isNumeric(elem, helperMsg){
    var numericExpression = /^[0-9]+$/;
    if(elem.value.match(numericExpression)){
        return true;
    }else{
        alert(helperMsg);
        elem.focus();
        return false;
    }
}


Unfortunately, because I'm a newbie I don't really understand how to u
+sefully incorporate the various modules that are out there.  I instal
+led the JavaScript::DataFormValidator module this morning, but am not
+ sure how to incorporate it yet.  The only modules I am utilizng in m
+y program currently are DBI and CGI.  I don't really know the details
+ of what they do.  I just know that the tutorials I've been taking to
+ld me to use them :)

The idea of putting my javascript into a perl string is intriguing.  H
+owever, it seems that my code could get real messy real quick.  Is it
+ common in Perl to call functions/variables/etc from an external Perl
+ file (like you can in JS "..SRC="/js_validation/js.js"></SCRIPT>" )?

If so, maybe storing my javascript in a variable within an external fi
+le would be a good way to do this?
