Its hard to say what goes wrong.<br>
<br>
First thing is to check that the taskpane (where some code is) is on
the EXACT same domain as the page serving the map.<br>
Javascript from a page at <a class="moz-txt-link-abbreviated" href="http://www.example.com">www.example.com</a> cannot access elements on a
page from www2.example.com (you need crossdomain, and that is hard to
get right).<br>
<br>
Second, you must take special care of race conditions, you cannot
control which page loads as the first.<br>
This is especially bad in IE, because the "onload" event from an
embedded iframe can fire _before_ the hosting page's "onload" event.<br>
<br>
The missing "clicked" function is most likely due to some other error,
which prevents the code defining "clicked" to be defined/initialized.<br>
<br>
In firebug, you can set a breakpoint at the line jg = new
jsGraphics(divID), and step into the code to see what is wrong.<br>

I have some javascript that initializes a jsGraphics object when my
taskPane loads. Currently, it loads in a div within the taskPane. And
before the page loads, I have a document.onkeydown and
parent.parent.mapFrame.onkeydown set to a function to capture key
presses and then do something. I have gotten the taskPane to recognize
mouse movements and mouse clicks that are within the mapFrame, and
currently, I use those to draw in the taskPane. I had tried what you
said already, and I found the map table and inserted my own div. To
test at first, I had put some text inside to see where(if at all) it
would show up, and within the 'map' table, it showed up on top of the
map. <br>
<br>
However, if I try to access it dynamically, after everything has loaded
it seems, I cannot. I have something like<br>
<code><br>
var map;<br>
var divID;<br>
var jg;<br>
.<br>
.<br>
.<br>
function init() {<br>
map = parent.parent.document.getElementsByTagName('frame')[1];<br>
divID = map.contentDocument.getElementById("mapSpace");<br>
jg = new jsGraphics(divID);<br>
}</code><br>
<br>
And when my code gets executed, the taskPane turns to a blank page, and
firebug throws numerous errors when I mouseover the map. The error it
seems to be giving me is 'clicked is not defined', which is a global
variable that has been declared and initialized.<br>
<br>
Am I unable to draw in the mapFrame once it has already been loaded?<br>
<br>
Also, somewhat unrelated, is IE7 not able to capture mouse movement or
key presses within the mapFrame from the taskPane? It doesn't seem to
react the same way as Firefox.<br>
<br>
Thanks for any help.<br>

What have you tried to do?<br>
<br>
If you look at the "ajaxmappane.templ" you can see how the mapFrame is
constructed.<br>
It is actually a table, so you may want the item "map" (a cell) or the
item "mapSpace" (a div).<br>
<br>
As long as you taskpane file and the mapframe is served from the same
server, there should be no problems.<br>
