eCard message conditional - how to?

Serge,

This is a little tricky. The Ecard content rendered with the S63 tag includes an intro line, "A message from <<sender name>> <<sender email>>", so S63 is actually never empty.

The only solution I can think of is to use JavaScript on the Ecard form to set a session variable indicating whether or not the sender has filled in a message. That would look something like this:

<img id="AjaxHelper" alt="" width="1" height="1" style="position:absolute;left:-999em;" src="AjaxHelper?s_isMessageEmpty=1" />
<script type="text/javascript">
var messageIsEmpty=true;
function isMessageEmpty(){
     var ecardMessage=document.getElementById('message');
     var ajaxHelper=document.getElementById('AjaxHelper');
     if(ecardMessage.value==''&&!messageIsEmpty){
          ajaxHelper.src='AjaxHelper?s_isMessageEmpty=1';
          messageIsEmpty=true;
     }
     else if(ecardMessage.value!=''&&messageIsEmpty){
          ajaxHelper.src='AjaxHelper?s_isMessageEmpty=0';
          messageIsEmpty=false;
     }
}
addOnLoadHandler(function(){
     var ecardMessage=document.getElementById('message');
     isMessageEmpty();
     Utils.addEvent(ecardMessage,'keyup',isMessageEmpty);
});
</script>

Then in the Ecard stationery, you'd use a conditional like this to test the session variable's value:

]x::<br /><strong>Personal Note:</strong><br/>::]]
]

Note that the "Personal Note:" text will appear above the aforementioned "A message from <<sender name>> <<sender email>>" text. If you want "Personal Note" to appear directly above the Ecard message itself, the conditional would need to go in the Message Catalog entry for "A message from {0} {1}."

Serge Tkachov:

Thanks Noah,

that is tricky!

Perhaps there is a less complex way..

I am thinking that perhaps I would like to test the message for emptyness on the form (I use API, so have full control of the client side)

and insert a key string into the message if message on the html form is not empty, say ***.

On html API form:

Something like this:

<script>

var o = getObject('ecard.message');

if( o ) {

    if( o.value != '' ) then o.value = '***'+o.value;

}

</script>

Then on eCard side do something like this (pseudocode):

if ecardMessage.contains("***") then

   print "<br /><strong>Personal Note:</strong><br/>"

   print ecardMessage

end if

How would I test the message for a presence of ***, and then display a title?

Thanks,

You could do that like so:

]::***::::<br /><strong>Personal Note:</strong><br/>]]
]

Bearing in mind the issue I noted before -- this text will appear above "A message from ..."
