Question

I have a webpage that contains ASP.NET panels and JavaScript that gets all of the components in the page:

var items = Sys.Application.getComponents();

I need to get the name/ID of each of the elements in the items variable. I have tried the following code: (but it doesn’t work)

for (var item in items) 
{
      alert(item.name);
}

What attribute of ‘item’ contains the name/ID? How can I modify the above code to do this?

Answer 1

Use the get_name() and get_id() functions instead.

var items = Sys.Application.getComponents() ;
for( var i = 0 ; i < items.length; i++ ) {
    var item = items[i];
    var id   = item.get_id();
    var name = item.get_name();
}
