    'buttonType'=>'submit',
    'name'=>'btnSubmit',
    'value'=>'1',
    'caption'=>'Submit form',
    'htmlOptions'=>array('class'=>'ui-button-primary')
    ),
));

To use this widget as a button, you may insert the following code in a view:

$this->widget('zii.widgets.jui.CJuiButton',array(
    'buttonType'=>'button',
    'name'=>'btnSave',
    'caption'=>'Save',
    'onclick'=>new CJavaScriptExpression('function(){alert("Save button clicked"); this.blur(); return false;}'),
));

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