YUI Library Examples: Drag & Drop: Using Handles

Basic Drag and Drop

The YUI Drag and Drop Utility lets you make HTML elements draggable.

For this example, we will enable drag and drop for the three <div> elements.

Create the demo elements:


1	<div id="dd-demo-1" class="dd-demo">
2	<div id="dd-handle-1a" class="dd-multi-handle-1">H1</div>
3	<div id="dd-handle-1b" class="dd-multi-handle-2">H2</div>
4	</div>
5	<div id="dd-demo-2" class="dd-demo">
6	<div id="dd-handle-2" class="dd-handle">H</div>
7	</div>
8
9	<div id="dd-handle-3b" class="dd-outer-handle">Outer</div>
10	<div id="dd-demo-3" class="dd-demo"></div>
	view plain \| print \| ?

Now we instantiate three YAHOO.util.DD instances. By default, a mousedown on any part of source element would start a drag operation. We use setHandleElId to make it so that only a specific area or areas of the source element will start a drag when clicked.

Elements that are not a child of the source element can be used as drag handles by using setOuterHandleElId.


1	<script type="text/javascript">
2
3	(function() {
4
5	var dd, dd2, dd3;
6	YAHOO.util.Event.onDOMReady(function() {
7	dd = new YAHOO.util.DD("dd-demo-1");
8
9	// Configure one or more child element as a drag handle
10	dd.setHandleElId("dd-handle-1a");
11	dd.setHandleElId("dd-handle-1b");
12
13	dd2 = new YAHOO.util.DD("dd-demo-2");
14	dd2.setHandleElId("dd-handle-2");
15
16	dd3 = new YAHOO.util.DD("dd-demo-3");
17	dd3.setHandleElId("dd-handle-3a");
18
19	// A handle that is not child of the source element
20	dd3.setOuterHandleElId("dd-handle-3b");
21	});
22
23	})();
24	</script>
	view plain \| print \| ?
