[PHP] help, please, understanding my problem

2010-02-22 Thread Stan 
I have a PHP page that has
 require_once(genMyOverlay.js.php);
 .
 .
 .
 echo body;
 echo script language=\JavaScript\doit(\mydiv\);/scriptbr;
 echo /body;

genMyOverlay.js.php contains: createDiv() (see below) that creates a DIV
ID=mydiv and sets it up to overlay a portion of the wbe page and
doit()starts it off.

invoke the web page once and it works like it should.  invoke the web page a
second time (and thereafter until a new session) and it gets error:
 doit is not defined

view the source (at the client browser) and it is identical both (all) times

can anyone please help me understand what is happening?

genMyOverlay.js.php contains
 script language=PHP
  echo script language=\JavaScript\;
  echo function createDiv();
  echo  {;
   .
   .
   .
  echo  };
  echo function doit(ElementID);
  echo  {;
  echo  creatDIV();
   .
   .
   .
  echo  };
  echo /script;
 /script

Going on just that sample, there's no issue. As it works the first time,
there isn't a problem with it not getting included. Have you tried it on
other browsers to see what happens there? Also, Firefox has a brilliant
addon called Firebug, which can show you the contents of included .js
files on your page, which will show up any problems you may have.

Aside from these points, have you a good reason for including a PHP file
that just outputs javascript? Why not just include the .js file as part
of the header?

Also, your script tags need a type attribute:

script language=javascript type=text/javascript

And lastly, instead of lots and lots of echo statements in your page,
have you looked at heredoc and nowdoc syntax in PHP?

echo EOC
lots and lots of output lines go here.
EOC;

Actually, you only need this:

script type=text/javascript

The language attribute will throw an error in validation.

Never thrown an error for me! I guess it depends on what doctype you
use?

I was trying to be discreet.

The language attribute has been depreciated. If you use a 
transitional DOCTYPE, then it won't throw an error -- but the 
language attribute is outdated and some consider it poor coding 
practice to use depreciated attributes.
