Actually it can be done but it is a bit tricky.
For example I have have an HTML doc with two SVG embeds. The first is
a map and the other is a legend. I need to initialize both SVG embeds
from the HTML and I need to control the map from the legend.
First the HTML. I set two globals:
------------------------------------
<script>
var MapDoc;
var LegDoc;
function init(evt) {
MapDoc = document.embeds[0].getSVGDocument();
LegDoc = document.embeds[1].getSVGDocument();
LegDoc.getElementById("minutes_local").setAttribute('transform',..
SVGDoc.getElementById('Basin_230').setAttribute('fill','white');
...
</script>
-------------------------------------------
The function init is called from the onload event of the body tag of
the HTML file. MapDoc and LegDoc gives the two embedded SVG files.
At that point you can manipulate either SVG DOM - I set a SVG clock in
the legend to the current time and color code the map based on
rainfall ammounts.
In the SVG documents it is a little different. I need the legend
document to control the map document.
In the legend file I have the following code:
-------------------------------------------
<script><![CDATA[
var ASV = navigator.appName.indexOf("Adobe") != -1;
var MapDoc = ASV ? self.document.embeds[0].getSVGDocument() :
parent.document.embeds[0].getSVGDocument();
function onoff(cbx,theme) {
legobj = document.getElementById(cbx);
mapobj = MapDoc.getElementById(theme);
......
}
]]></script>
--------------------------------------------
First a global variable is defined to see if you are using the Adobe
plugin or not (ASV is true if you are, false if not).
Then the global MapDoc is set to the first embed depending on the
value of the ASV variable. At this point you are ready to go. In my
example above the function onoff controls an element in the legend
document (legobj) and an element in the map document (mapobj).
When I wrote this it was working with Firefox 1.0 with the Adobe SVG
beta plugin installed in Firefox. It works now in the native Firefox
1.5 with no plugin.
Hope this helps.
