Drag & Drop: Window Scrolling

+ + + +

Setting up the Node

First we need to create an HTML Node to make draggable.

<div id="demo"><h2>x</h2>Drag Me</div>

<div id="demo"><h2>x</h2>Drag Me</div>

Now we give that Node some CSS to make it visible.

#demo {
    height: 100px;
    width: 100px;
    border: 1px solid black;
    background-color: #8DD5E7;
    padding: 7px;
}
#demo h2 {
    padding: 0;
    margin: 0;
    position: absolute;
    top: 5px;
    right: 5px;
    font-size: 110%;
    color: black;
    font-weight: bold;
    cursor: move;
}

#demo {
+    height: 100px;
+    width: 100px;
+    border: 1px solid black;
+    background-color: #8DD5E7;
+    padding: 7px;
+}
+#demo h2 {
+    padding: 0;
+    margin: 0;
+    position: absolute;
+    top: 5px;
+    right: 5px;
+    font-size: 110%;
+    color: black;
+    font-weight: bold;
+    cursor: move;
+}

Setting up the YUI Instance

Now we need to create our YUI instance and tell it to load the dd-drag and dd-scroll modules.

YUI().use('dd-drag', 'dd-scroll');

YUI().use('dd-drag', 'dd-scroll');

Making the Node draggable with DD

Now that we have a YUI instance with the dd-drag and dd-scroll modules, we need to instantiate a DD instance from this Node.

var dd = new Y.DD.Drag({
    node: '#demo'
}).addHandle('h2');

var dd = new Y.DD.Drag({
+    node: '#demo'
+}).addHandle('h2');

Making the Window Scroll

Now that we have a draggable Node, we need to plug the Plugin.DDWinScroll plugin onto the Drag instance.

var dd = new Y.DD.Drag({
    node: '#demo'
}).addHandle('h2').plug(Y.Plugin.DDWinScroll);

var dd = new Y.DD.Drag({
+    node: '#demo'
+}).addHandle('h2').plug(Y.Plugin.DDWinScroll);
