/**
* CJuiSliderInput displays a slider. It can be used in forms and post its value.
*
* CJuiSlider encapsulates the {@link http://jqueryui.com/slider/ JUI
* slider} plugin.
*
* To use this widget, you may insert the following code in a view:
* <pre>
* $this->widget('zii.widgets.jui.CJuiSliderInput',array(
* 'name'=>'rate',
* 'value'=>37,
* // additional javascript options for the slider plugin
* 'options'=>array(
* 'min'=>10,
* 'max'=>50,
* ),
* 'htmlOptions'=>array(
* 'style'=>'height:20px;',
* ),
* ));
* </pre>
*
* The widget can also be used in range mode which uses 2 sliders to set a range.
* In this mode, {@link attribute} and {@link maxAttribute} will define the attribute
* names for the minimum and maximum range values, respectively. For example:
*
* <pre>
* $this->widget('zii.widgets.jui.CJuiSliderInput',array(
* 'model'=>$model,
* 'attribute'=>'timeMin',
* 'maxAttribute'=>'timeMax',
* // additional javascript options for the slider plugin
* 'options'=>array(
* 'range'=>true,
* 'min'=>0,
* 'max'=>24,
* ),
* ));
* </pre>
*
* If you need to use the slider event, please change the event value for 'stop' or 'change'.
*
* By configuring the {@link options} property, you may specify the options
* that need to be passed to the JUI slider plugin. Please refer to
* the {@link http://api.jqueryui.com/slider/ JUI Slider API} documentation
* for possible options (name-value pairs) and
* {@link http://jqueryui.com/slider/ JUI Slider page} for general
* description and demo.
