Question

updating javascript in the body tag using zend framework

Answer 1

+2 A:

Instead of putting your Javascript directly in the code, you could also use an non-obstrusive approch : plugging in the javascript when the page is fully loaded.

Have a look, for instance, at a function called addOnLoadEvent (can be found on many websites ^^ )

If you are using a JS Framework, it certainly has that kind of feature :

for jQuery : http://docs.jquery.com/Events/ready#fn
for prototype : http://www.prototypejs.org/api/event/observe

If you register the "plugging-in" with headScript, there should be no need to modify the tag directly.

Answer 2

A:

I'm no expert on the Zend framework, so I don't know if there is any build in functions for this, but you could do something like this: In layout-file: body_params?>>

And then in your controller, you set or add to the body_params:

$this->view->body_params='onload="initialize()" onunload="GUnload()"';

Answer 3

+3 A:

Approach one - Use a layout variable

One idea would be the following:

<body class="trandra" <?php echo $this->layout()->bodyScripts ?>>

And in your view:

<?php
   $this->layout->bodyScripts = 
       'onload="initialize()" onunload="GUnload()"';

Approach two - Additional JS-file that adds event handlers

Another approach, which is less obtrusive and doesn't affect the HTML whatsoever is to add an additional JS-file in the view that requires the onload- and onunload-handlers. It could look something like this:

<?php
   $this->headScript()->appendScript(
                         '/path/to/javascripts/loadGMaps.js');

In your loadGMaps.js (using prototype)

Event.observe(window, 'load', function onLoadHandler() {
    // Code for initializing Google maps here
});

Event.observe(window, 'unload', function onUnloadHandler() {
    // Code for unloading Google maps here
});

Hi guys,

Developed something like this recently, I've blogged about it here: http://www.evilprofessor.co.uk/311-zend-framework-body-tag-view-helper/

Demo on site and code is available via github.

Cheers, Lloyd.
