+<script type="text/javascript">
+    function handleError() {
+        return true;
+    }
+    window.onerror = handleError;
+</script>
+<script type="text/javascript" language="javascript">
+    function doCallback1(param1, param2, param3) {
+        Callback1.Callback(param1, param2, param3);
+    }
+    function doCallback2(param1, param2, param3) {
+        Callback1.Callback(param1, param2, param3);
+        Callback2.Callback(param1, param2, param3);
+        Callback3.Callback(param1, param2, param3);
+    }
+    function doCallback3(param1, param2, param3) {
+        Callback2.Callback(param1, param2, param3);
+        Callback3.Callback(param1, param2, param3);
+    }
+
+    function InitLocation(division) {
+        clbDivision.Callback(division);
+    }
+</script>
+{% endhighlight %}
+
+I'm not sure what's worse - The fact that all JavaScript errors are silently ignored, doCallback2 
+having three callbacks and doCallback3 having two callbacks, or the use of globals (Callback1, 
+Callback2, Callback3). The same site had JavaScript functions with names like "foo" and "bar".
+
+As a side note, an interesting oddity in JavaScript: When you return true in the window.onerror 
+handler, this prevents the default event handler. This is the opposite to all the other DOM 0 
+events (such as onclick), where returning false prevents the default handler.
