<div class="exampleIntro">
|
|
<p>This example demonstrates a vertical implementation of the <a href="http://developer.yahoo.com/yui/slider/">YUI Slider Control</a>. Some characteristics of this implementation include the following:</p>
|
|
<ul>
|
|
<li>The slider range is 200 pixels.</li>
|
|
<li>CSS is used to place the slide thumb at the bottom of the slider.</li>
|
|
<li>Custom logic is added to the slider instance to convert the offset value to a "real" value calculated from a provided min/max range.</li>
|
|
<li>The custom min value is set to 10; the max 110.</li>
|
|
<li>Once the slider has focus, the up and down keys will move
|
|
the thumb 20 pixels (changing the "real" value by 10).</li>
|
|
<li>When the slider value changes, the pixel offset and calculated value are reported below the slider.</li>
|
|
</ul>

<h2 class="first">Building a Bottom-Up Vertical Slider</h2>
|
|
|
|
<p>You supply your own markup for the slider. Keep in mind the following points about markup for <a href="http://developer.yahoo.com/yui/slider/">YUI Slider Control</a> implementations:</p>
|
|
<ul>
|
|
<li>The thumb element should be a child of the slider background</li>
|
|
<li>The tabindex attribute lets this element receive focus in most browsers.</li>
|
|
<li>If the slider background can receive focus, the arrow keys can be used to change
|
|
this slider's value.</li>
|
|
<li>We use an <code><img></code> element rather than a CSS background for the thumb to get around
|
|
a performance bottleneck when animating the thumb's position in IE.</li>
|
|
<li>Both elements should have an explicit CSS position: <code>relative</code> or <code>absolute</code>.</li>
|
|
<li>Don't apply a CSS border to the slider background</li>
|
|
</ul>
|
|
|
|
<p>CSS:</p>
|
|
<textarea name="code" class="CSS" cols="60" rows="1">
|
|
#slide_bg {
|
|
position: relative;
|
|
background: url(assets/bg-v.gif) 12px 0 no-repeat;
|
|
height: 228px;
|
|
width: 48px;
|
|
}
|
|
|
|
#slide_thumb {
|
|
cursor: default;
|
|
position: absolute;
|
|
top: 200px; /* To initialize the slide thumb at the bottom */
|
|
}
|
|
</textarea>
|
|
|
|
<p>Markup:</p>
|
|
<textarea name="code" class="HTML" cols="60" rows="1">
|
|
<div id="demo">
|
|
|
|
<div id="slide_bg" tabindex="-1">

<h2>Invert the <code>getValue</code> offset</h2>
|
|
<p>Offset values returned by the <code>getValue()</code> methods, or passed as a parameter to the <code>change</code> event callback, increase as the slider moves left-to-right and top-to-bottom. Making the value increase in the opposite direction is as simple as multiplying by -1.</p>
|

<p>Look for the magic in this code:</p>

var offset_span = YAHOO.util.Dom.get('d_offset');

|
|
|

<p>For horizontal Sliders, multiplying the offset by -1 makes values increase right-to-left.</p>
