[Dynapi-Help] Extending the List widget - dynapi.gui.list.js

[Jeevan_Sunkersett <Jee...@sa...>]

Hi,

I was successful in extending the List widget as MyList with:

	<script>
	function MyList()
	{
		this.dynlayer = List;
		this.selectedIndex = List.selectedIndex;
		this.selectedItem = List.selectedItem;
		this.ievents = new EventListener(this);
		this.ievents.onselect = function(e) {
			e.getTarget().select(e.getSource());
		}
		this.ievents.ondeselect = function(e){
  			e.getTarget().deselect(e.getSource());
		};
		return this;
	}

	MyList.prototype = new List();
	
	MyList.prototype.select = function(item)
	{
		alert("in myList select func " + this.getIndexOf(item));
//this works
		window.url = http://localhost:8090 <http://localhost:8090>
//but this does not! Why ?
	}
	MyList.prototype.deselect = function(item)
	{
		//how to call super() - The deselect function provided in
the List widget
	}

	</script>

1>But I do not wish to code a "deselect" function in MyList. 
    It should call the default deselect() of List.js.
    I could not figure out how to do this.
    With an OOP like java I would normally call super() but what to do in
case of JavaScript ?

2> The alert() in the select function returns the selected index correctly,
but the following line (to redirect to a another page) does not function.
