A topic of concern in Linux

[Darragh]

Here are two common scripts that I use.

This doesn't stop users completely from right clicking on my site but it
certainly makes it more difficult.

<script LANGUAGE="JavaScript">
<!--var message="Sorry, You do not have permission to Right-Click on this
Page.";
function click(e) {
 if (document.all) {
  if (event.button == 2) {
   alert(message);
   return false;
  }
 }
 if (document.layers) {
  if (e.which == 3) {
   alert(message);
   return false;
  }
 }
}
 if (document.layers) {
  document.captureEvents(Event.MOUSEDOWN);
 }
document.onmousedown=click;

functions for validating a form. .
function echeck(str) {

  var at="@"
  var dot="."
  var lat=str.indexOf(at)
  var lstr=str.length
  var ldot=str.indexOf(dot)
  if (str.indexOf(at)==-1){
     alert("Invalid E-mail address")
     return false
  }

  if (str.indexOf(at)==-1 || str.indexOf(at)==0 || str.indexOf(at)==lstr){
     alert("Invalid E-mail address")
     return false
  }

  if (str.indexOf(dot)==-1 || str.indexOf(dot)==0 ||
str.indexOf(dot)==lstr){
      alert("Invalid E-mail address")
      return false
  }

   if (str.indexOf(at,(lat+1))!=-1){
      alert("Invalid E-mail address")
      return false
   }

   if (str.substring(lat-1,lat)==dot || str.substring(lat+1,lat+2)==dot){
      alert("Invalid E-mail address")
      return false
   }

   if (str.indexOf(dot,(lat+2))==-1){
      alert("Invalid E-mail address")
      return false
   }

   if (str.indexOf(" ")!=-1){
      alert("Invalid E-mail address")
      return false
   }

    return true
 }
function ValidateForm(){
 var emailID=document.Feedback.emailaddress

 if (Feedback.name.value == ""){
  alert("Please enter your name.  You must fill out fields marked with a
*");
  Feedback.name.focus();
  return;
 }

 if ((emailID.value==null)||(emailID.value=="")){
  alert("Please Enter your Email address.  Fields marked with a * must be
completed")
  emailID.focus()
  return false
 }
 if (echeck(emailID.value)==false){
  emailID.value=""
  emailID.focus()
  return false
 }
 return true
 }

I know it's heavily used, but why is it better and/or more useful? More to
the point, how does its proper use make it more effective than not using
it, especially in light of all the ways it's used to, as the Car Talk guys
say, obfuscate and de-clarify?

it is heavily used in navigation and forms. I have built several
websites that use javascript navigation and basic form varification
such as email addresses and stuff.

Always borrow money from a pessimist; he doesn't expect to be paid
