+ <p>This example walks you through the basics of creating a Slider from script.
+ Both Sliders in this example link to text input fields that expect numeric input. The first Slider uses the default configuration, spanning values between 0 and 100, and is rendered inline.</p>
+
+ <p>The second Slider is configured to orient vertically (along the y axis) and the configuration includes minimum, maximium, and initial values. It is rendered into a <code></div></code>.</p>
+
+ <p>The first Slider is set up in a more traditional JavaScript coding style and
+ the second using the shorter, method chaining style.</p>

+
+<h3>Horizontal Slider with default configuration</h3>
+<p>Sliders are horizontal by default, with available values ranging from 0 to 100, and an initial value of 0. The rail is 150 pixels long plus a few pixels for the rail's end caps.</p>
+
+<pre class="code prettyprint">var xSlider = new Y.Slider();
+
+// render into the <span> next to the input
+xSlider.render( ".horiz_slider" );</pre>
+
+
+<h3>Linking a Slider with a text input</h3>
+<p>To keep the Slider's value and input value in sync, you need to subscribe to events on both the input and the Slider. For Slider-to-input, the interesting event is <code>valueChange</code>.</p>
+
+<pre class="code prettyprint">// Function to update the input value from the Slider value
+function updateInput( e ) {
+ this.set( "value", e.newVal );
+}
+
+var xInput = Y.one( "#horiz_value" );
+// Subscribe to the Slider's valueChange event, passing the input as the 'this'
+xSlider.on( "valueChange", updateInput, xInput );</pre>
+
+
+<h3>Linking the input with the Slider</h3>
+<p>To feed input changes back to the Slider we'll listen to its <code>keyup</code> event. But we'll put the update on a delay to allow for a user to finish typing.</p>
+
+<p>Additionally, we'll make the update function generic, since we have two Sliders in this example. We'll leverage the <code>setData</code> and <code>getData</code> methods of Node instances and store a reference to the Slider. Then we can use this object from inside the function to get back to the slider the input is related to.</p>
+
+<pre class="code prettyprint">// Function to pass input value back to the Slider
+function updateSlider( e ) {
+ var data = this.getData(),
+ slider = data.slider,
+ value = parseInt( this.get( "value" ), 10 );
+
+ if ( data.wait ) {
+ data.wait.cancel();
+ }
+
+ // Update the Slider on a delay to allow time for typing
+ data.wait = Y.later( 200, slider, function () {
+ data.wait = null;
+ this.set( "value", value );
+ } );
+}
+
+xInput.setData( { slider: xSlider } );
+xInput.on( "keyup", updateSlider );</pre>
+
+
+<h3>Creating the vertical Slider</h3>
+<p>To create a vertical Slider you just need to set the <code>axis</code> attribute to "y".</p>
+
+<p>For this Slider, we'll use more extensive method chaining and include value and rail configurations. First we'll change the value range from 0 - 100 to -100 - +100 and set an initial value of +30.</p>
+
+<p>Note that the <code>min</code> configuration is 100 in this case because the top is associated with the minimum value. Slider has no qualms about <code>min</code> being greater than <code>max</code>.</p>
+
+<p>The rail length is then configured to be 201 pixels, so each value has a distinct pixel position on the rail (don't forget 0).</p>
+
+<p>Finally, the <code>valueChange</code> subscription is included in the configuration as well.</p>
+
+<pre class="code prettyprint">var yInput = Y.one( "#vert_value" );
+yInput.setData( "slider", new Y.Slider({
+ axis: 'y',
+ min : 100, // min is the value at the top
+ max : -100, // max is the value at the bottom
+ value : 30, // initial value
+ length: '201px', // rail extended to afford all values
+
+ // construction-time event subscription
+ after : {
+ valueChange: Y.bind( updateInput, yInput )
+ }
+ }).render( ".vert_slider" ) // render returns the Slider
+ ) // set( "data", ... ) returns the Node
+ .on( "keyup", updateSlider ); // chain the keyup subscription</pre>
