[mapguide-users] OnSelection Event?

Fri May 5 03:21:37 EDT 2006

Ok, I came across a short sample in one of the documentations and
created this very simple page:

<?

// testing the getXMLSelection...

// testframe

// ViewerFrame (map contents)

?>

<html>

<head>

</head>

<script>

function doXml()

{

            xmlSel = parent.ViewerFrame.mapFrame.GetSelectionXML();

            params = new Array("test","1", "SEL", xmlSel);

parent.ViewerFrame.formFrame.Submit("http://localhost/sites/viewer/mytes
t.php", params, "taskPaneFrame"); 

}

</script>

<body>

<?

if($_POST['test']==1)

{

            echo $_POST['SEL'];

}else

{

?>

<a href="#" onClick="doXml();">Show it!</a>

<?

}

?>

</body>

</html>

First I will select an object on the map, next I will click the  'Show
it!' link...

In the taskpaneframe the mytest.php file is loaded. If I look at the
source there is a piece of XML:

<?xml version="1.0" encoding="UTF-8"?>

<FeatureSet>

<Layer id="8fa14c82-ffff-ffff-8000-0014a40277a1">

<Class id="Default:lki_v">

<ID>rBAAAA==</ID>

</Class>

</Layer>

</FeatureSet>

How can I use this to get the properties from this object on the map?

Is still need this mytest page to be executed automatically on selection
of the object..

Thanks

I've just read the dev manual and want to try to create a little test
program, to get me started on understanding the flow of events etc.. 

What I want is:

When something gets selected, read a property and call an asp-page in
another frame (in short).

But how can I tell if something is selected?

I suppose there is no onSelectionChanged event like in MG6.5. So this
would be done on a onClick? Where would I put the code for this?
