<p class=MsoNormal>This code is using the sample gotopoint.aspx file. When
I select the link that activates this gotopoint, the URL contains the X Y and
scale <a
href="http://172.16.186.38/mapguide2010/UtilityMap/gotopoint.aspx?X=632593.974151717&Y=4989398.03115329&Scale=25000">http://172.16.186.38/mapguide2010/UtilityMap/gotopoint.aspx?X=632593.974151717&Y=4989398.03115329&Scale=25000</a>
which should be passed into this onPageLoad() function. However it
appears that nothing is firing for OnPageLoad – so when I click the link
nothing happens, no error message or anything.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone help with this problem? Also, can anyone
point me to something that would help explain this parent.parent. syntax?
I’m not really certain why at one point we would use parent.function() vs
parent.parent.parent.function() etc.<o:p></o:p></p>

</div>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hi List,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m making steady progress with my project and
learning many things about MapGuide along the way thanks largely to the help
from those on this list – many thanks to those who have helped so far<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>From what I can tell parent.parent.parent.mapFrame is how
the map frame is referenced from the task pane in the AJAX viewer. I have
been reading posts about how this is referenced in Fusion and it seems the <i>MapGuideViewerAPI.js</i>
file has a bit of info. Unfortunately I’m having a bit if trouble
putting the pieces together and was hoping that someone here may steer me in
the right direction.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In both AJAX and FUSION I’m working from the taskpane
and using the markup scripts that are part of the AJAX demo’s and
tutorials.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I assume I need to substitute either ‘Fusion’ or
‘window.top.Fusion’ somehow for ‘<i><span style='font-size:
10.0pt;font-family:"Courier New"'>parent.parent.parent.mapFrame.DigitizePoint(OnPointDigitized);’.
</span></i>in my script however I have yet to do this in such a way that it
works. I keep getting ‘Object doesn’t support this property
or method’.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So for example in my editmarkup.aspx code for example, I
have the following function which should be activated when I click the digitize
point button<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='text-autospace:none'><i><span style='font-size:10.0pt;

<p class=MsoNormal style='text-autospace:none'><i><span style='font-size:10.0pt;

}</span><o:p></o:p></i></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In Fusion this code gives an error
‘parent.parent,parent.mapFrame’ is null or not an object<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I see that in MapGuideViewerAPI.js<o:p></o:p></p>
