Evan, Are you proposing something like AJAX does? My understanding is limited here, so bear with me. A control like a hidden imbedded frame (IFRAME) is acted upon by Javascript to cause it to dynamically request loading a page into the frame, and when loaded, the javascript processes the contents of the frame without necessarily displaying it directly?

Been there, done that technique... unfortunately it can't be used to
dynamically load script that will be seen by the currently executing
scope... this isn't quite true... I think one browser saw it right off,
another saw it if I used eval on the retrieved source, but other
browsers don't see it until after the scope (function scope) exits. The
exact semantics are quite varying which provides for completely
unreliable loading of dyanamic script -- and to be frank I try to make
my stuff work with IE/FF/Opera. I could care less about NN4 in this day
and age :)

Rob.

RE: [PHP] New Help with Javascript Navigation
You are absolutely correct, that anything that ran on the client machine would have to be safe and not venture outside the sandbox, but that is not what I had in mind, and I don't think that was the goal of PUB? Who began this thread. I believe he wanted to manage some responses to mouseover, and was sent to another list to find his answer. You are right on again with the understanding that much of the power and elegance of PHP would not be available for this type of coding, but there still is a need and a reason people are forced to turn to Javascript (which is also limited to the sandbox), starting with simple interactive data validation, and moving right on up to managing images, or changing control behaviors and such. I just think it would be nice to be able to do it all in PHP, it's such a graceful language to work with. Meanwhile, I think I'll check out PHPScript, that Richard Lynch found, as soon as I can.

What if there was a function that accepted PHP code as input and tranlated it to Javascript, returning the resulting text ready for imbedding in html? Any creative masochists out there? Has it already been attempted?

Unfortunately your last post contained several problems; a. It was to long. 2. it was a JavaScript question.

RE: [PHP] New Help with Javascript Navigation
Sounds like you may be a young dude ;-) You know what they say about us old dogs and new tricks. PHP was a wonderful new trick for me, but javascript still stretches me a bit much, and if it weren't for the similarities you mention, I'd be completely lost. I think the reason we keep getting questions about Javascript on this list, is because others are struggling with it as I am. It would be nice if it were covered by PHP. Just think how it would be if you could write PHP that could access the browser object model and alter settings on the clients screen dynamically, of course, at some stage it would be necessary to implement a means of communicating back to the server, but just to be able to provide interaction on the client machine would be a great start.

Developers get all excited about the elegence of the PHP language, and somewhere along the way they discover they have been sandbagged (they have to learn Javascipt too, if they want responsive GUI's). One solution would be to develop a PHP Plugin and support that for all the browsers out there, but another just occurred to me. What if there was a function that accepted PHP code as input and tranlated it to Javascript, returning the resulting text ready for imbedding in html? Nice idea, although sandbagged sounds like an exageration: becoming fluent in both PHP JavaScript is hardly a major life challenge. When I finally learned PHP I was delighted at how syntactically similar it was to JavaScript, compared say to the difference between JavaScript VBscript. Perhaps my most common mistake in writing in both PH JS is that I tend to use . as a concatenation operator in JavaScript these days...

It would be possible to write a script which took $a = 3 and converted it into var a = 3, but a huge number of PHP functions either can't be implemented in Javascript (file_get_contents) or are fundamentally unsafe to implement in Javascript (mysql_query), so you'd end up with a language you couldn't do anything with. To the contrary, client-side PHP would simply be a different environment from server-side PHP -- of course certain functions wouldn't apply and others would that aren't relevant to server-side PHP, but that's not rocket science. The point would be to use the same syntax in both contexts. Relevant to this discussion, there is a set of PHP DOM functions (native to the core) that look like they match with the corresponding JavaScript functions pretty closely: http://php.net/dom I haven't used them yet, but the function names look familiar. The way I might implement such a PHP-JavaScript translation might look like this: script type=text/javascript src=phpToJavaScript.php?src=myscript.php/script where phpToJavaScript.php is the translation program and myscript.php is the client-side PHP script to be translated to JavaScript.
