Param | Type | Details |

e | Object | An event object which contains the item |
This event can be handled by binding the 'itemadded' event to the TreeView widget object.
Supported in: v1.0.
In this example we are showing how to handle itemadded event in TreeView widget.
$(document).ready(function() {
// Create an instance of TreeView widget
var $tree = $('#treeview').treeview();
// Get the number of present items in TreeView
var getItemCount = function(){
return $tree.treeview("getList").length + 1;
}
// Create a new item with its header title
var createNewItem = function(){
return { text: "Item" + getItemCount() };
}
// When 'Add Item' button is clicked, add a new item to the TreeView
var add = function(){
var item = $tree.treeview("addItem", createNewItem());
}
// Create a handler to the itemadded event
$tree.on({
"itemadded": function(e){
console.log("itemadded event was fired for item: " + e.object.text);
});
});
