Inheritance class CJuiSliderInput » CJuiInputWidget » CJuiWidget » CWidget » CBaseController » CComponent
Since 1.1
Source Code framework/zii/widgets/jui/CJuiSliderInput.php
CJuiSliderInput displays a slider. It can be used in forms and post its value.

CJuiSlider encapsulates the JUI slider plugin.

To use this widget, you may insert the following code in a view:
$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;',
    ),
));


The widget can also be used in range mode which uses 2 sliders to set a range. In this mode, attribute and maxAttribute will define the attribute names for the minimum and maximum range values, respectively. For example:

$this->widget('zii.widgets.jui.CJuiSliderInput',array(
    'model'=>$model,
    'attribute'=>'timeMin',
    'maxAttribute'=>'timeMax',
    // additional javascript options for the slider plugin
    'options'=>array(
        'range'=>true,
        'min'=>0,
        'max'=>24,
    ),
));


If you need to use the slider event, please change the event value for 'stop' or 'change'.

By configuring the options property, you may specify the options that need to be passed to the JUI slider plugin. Please refer to the JUI Slider API documentation for possible options (name-value pairs) and JUI Slider page for general description and demo.
