Is it possible for a module to insert custom values into the body tag of a dynamic view page? I'm trying to write my own version of a google maps module, and I need to insert onload="initialize()" into the body tag to make the map load automatically (right now I've got a "click here to load the map" link instead). Is there a way to do that?

I don't know how, but it looks like that stuff is inserted into the theme:

See /themes/default/views/page.html.php

<body <?= $theme->body_attributes() ?>>

That function is defined in /modules/gallery/libraries/MY_View.php

And right now it looks like it's not doing anything other than checking if you have a right-to-left language and if so, sets a class for that.

I don't know how to extend that, but you're the plugin machine so maybe you can't figure that out. And share it with me :)

I saw that function call too, but it doesn't take any variables :(

Oh well, it works well enough with the "Load Map" button. If I can't figure something out before I finish the rest of the code maybe I'll load the map inside of an iframe or something.

You can call initialize from within the code, you don't need to do it from the onLoad() in the body tag.
See if this works:

<script src="http://www.google.com/jsapi?key=xxxxxxxxxxxxxxxxxxxxx" type="text/javascript"></script>
<script type="text/javascript">
google.load("maps", "2");
// Call this function when the page has been loaded
      function initialize() {
        var map = new google.maps.Map2(document.getElementById("map"));
		map.addControl(new GSmallMapControl());
        map.setCenter(new google.maps.LatLng(33.214635, -87.545199), 14);
		
		var point = new GLatLng(33.214761, -87.545156);
		
		var marker = new GMarker(point);
		GEvent.addListener(marker, "click", function() {
			marker.openInfoWindowHtml("<a href='http://maps.google.com/maps?f=d&hl=en&geocode=&saddr=7th+St+%4033.214761,+-87.545156&daddr=&sll=33.213199,-87.544899&sspn=0.024164,0.040169&ie=UTF8&ll=33.215838,-87.545285&spn=0.024163,0.040169&z=15&om=1'>The Career Center</a><br/>330 Ferguson Center<br/>Tuscaloosa, AL<br/>35487");
			}
		);
		map.addOverlay(marker);
		
      }
      	google.setOnLoadCallback(initialize);
</script>

Just in case, I just tweaked the code to allow modules to add their own hooks in your xxx_theme helper so that you can override body_attributes.
