Give message for empty tree

[sathiyaseelan8Participant]

hi,

i did a function using jqxtree(JSON) and its working fine.

i need to know how to display a message, when there is no data to display in jqxtree.

example message: no data to display.

here is my code

<script type="text/javascript">
            $(document).ready(function () {
				var theme = 'ui-redmond';
				
				$('#submit').click(function() {
					//validate fields
					
					if(document.getElementById('txt_input').value == '')
					{
						alert("Please enter a value");
					}
					else
					{
						disp_tree();
					}
				});
				
                // prepare the data
            var disp_tree = function() {
				$('#jqxWidget').html('<img src="js/jqwidgets/resources/loader_2.gif"><img>');
			
				var search = document.getElementById('txt_input').value;
				var cate = document.getElementById('ddl_list').value;
				
				var source =
					{
						datatype: 'json',
						datafields: [
							{ name: 'id' },
							{ name: 'parentid' },
							{ name: 'text' },
							{ name: 'value' }
						],
						//theme: theme,
						url: 'tree_view.php?search='+search+"&cate="+cate,
						id: 'id',
						root: 'data',
						async: false
					};
					// create data adapter.
					var dataAdapter = new $.jqx.dataAdapter(source);
					// perform Data Binding.
					dataAdapter.dataBind();
					// get the tree items. The first parameter is the item's id. The second parameter is the parent item's id. The 'items' parameter represents 
					// the sub items collection name. Each jqxTree item has a 'label' property, but in the JSON data, we have a 'text' field. The last parameter 
					// specifies the mapping between the 'text' and 'label' fields.  
					var records = dataAdapter.getRecordsHierarchy('id', 'parentid', 'items', [{ name: 'text', map: 'label'}]);
					$('#jqxWidget').jqxTree({ source: records, width: '300px'});
				};
            });
    </script>

thank you.

Hello sathiyaseelan8,

Unfortunately, there is no way to display a message.
