<br>
thanks for giving such a useful site <br>
<br>
Just for learning I am trying to show the number of objects selected <br>
Below is my code taken from that site But <b><span style='font-weight:bold'>not
working</span></b><br>
<br>
<br>
<b><span style='font-weight:bold'>Not showing the number of objects selected in
alert box</span></b> <br>
<br>
///////****************************************/Handling viewer

//Function variable to store the original OnSelectionChanged <br>
var origOnSelectionChanged = null; <br>
<br>
//Our custom selection handler <br>
function MySelectionHandler() <br>
{ <br>
//This is important. We don't want to replace the original
function, rather <br>
//we want to attach our code into the execution sequence. So we
call the original <br>
//function first. <br>
origOnSelectionChanged(); <br>
<br>
//Now our code goes here. For our example, we'll just show the
number of objects selected. <br>
var count = viewerFrame.GetMapFrame().GetSelectedCount(); <br>
alert(count + " features selected"); <br>
} <br>
window.onload = function() <br>
{ <br>

is <br>
// repeatedly checking the mapInit value of the Map Frame. When <br>
// mapInit is true, then the map has been loaded. <br>
var watch = function() <br>
{ <br>
<br>
// What we are doing here is attempting to access
the mapInit <br>

is in a try-catch <br>

clearInterval(timer); <br>
<br>
// Replace the
OnSelectionChanged function with our own function. <br>
// It is safe to do
this now because the DOM for the map frame is fully initialized. <br>

// Store old function <br>
