Back to the original javascript problem...

I think you could do without the condition parameters on the else condition...either that, or change the 'else' to an 'else if'.

the syntax should either be:

else {

}

OR...

else if (Ticket.PaymentType.options[Pmt].value == 6)

That works with CF in CFScript also... I like to use it with functions
sometimes for the number of arguments:

switch (arraylen(arguments)) {
        case "1": { argument2 = yadda; }
        case "2": { argument3 = yadda; }
        default: { yadda; }
}

Makes it a little easier than having multiple comparisons of the
number of arguments.

The delimitered case statements are a bit different -- you can't have
the same value in two case blocks, so for instance you can't say:

<cfcase value="1"></cfcase>
<cfcase value="1,2"></cfcase>

Delimiters are nice, but they still don't allow quite the same
functionality as the cfscript switch statement (granted, you don't get
delimiters in cfscript either, so there are pros and cons either way).
Personally I think it would have been nice if they'd provided a way of
allowing the tag-based case statements to cascade, like

<cfswitch cascade="true">
  <cfcase value="1">
    blah blah blah
    <cfbreak>
  </cfcase>
  <cfcase value="2"></cfcase>
  <cfcase value="3"></cfcase>
</cfswitch>

Which would allow you to get the same functionality from a tag-based
switch. But it's such a "one-off" feature (so infrequently mentioned)
I doubt it'll ever be implemented.


Might be a little easier to read with a select/case   ;)
It works just like the CF one, except you need to use a
break statement where you want it to stop processing.
(pretty powerful that way - can have multiple case blocks
cascade)



 function checkCCAccount(Ticket) {
   var pmt = Ticket.PaymentType.options[Ticket.PaymentType
   .selectedIndex].value;
   switch(pmt){
    case 1:
      alert(pmt + "You must enter the account information
      if you are paying by Corporate Check");
      break;
    case 3: case 4: case 5: case 6:
      alert(pmt + "Please note that your credit card will
      be process at the time of the service call");
      break;
   }
 }



a lot of people dont realize you can do the same thing in
cold fusion - have a multiple values for a single
case statement with delimiters in it.  i.e. -


<cfswitch expression="#myValue#">
  <cfcase value="1,2">
                <!--- for values 1, 2 --->
 </cfcase>
 <cfcase value="3,4,5,6">
                <!--- for values 3, 4, 5, 6 --->
 </cfcase>
 </cfswitch>


just a tid bit that gets overlooked a lot it seem, so
worth mentioning :)

  Ahh. My arch nemesis, JavaScript. I am having issues
  with this piece of code:


  function checkCCAccount(Ticket) {
    Pmt = Ticket.PaymentType.selectedIndex
     if (Ticket.PaymentType.options[Pmt].value == 1); {
      alert(Ticket.PaymentType.options[Pmt].value + "You
      must enter the account information if you are paying
      by Corporate Check");
     }
     else if (Ticket.PaymentType.options[Pmt].value == 3);
     {
      alert(TIcket.PaymentType.options[Pmt].value +
      "Please note that your credit card will be process
      at the time of the service call");
     }
     else if (Ticket.PaymentType.options[Pmt].value == 4);
     {
      alert(TIcket.PaymentType.options[Pmt].value +
      "Please note that your credit card will be process
      at the time of the service call");
     }
     else if (Ticket.PaymentType.options[Pmt].value == 5);
     {
      alert(TIcket.PaymentType.options[Pmt].value +
      "Please note that your credit card will be process
      at the time of the service call");
     }
     else (Ticket.PaymentType.options[Pmt].value == 6); {
      alert(TIcket.PaymentType.options[Pmt].value +
      "Please note that your credit card will be process
      at the time of the service call");
     }
    }

I keep getting a syntax error. Any takers?

Thanks,

Bruce
