I'm trying to add a further function on to the HorizontalSlider onChange function, unfortunatly when I do this through the constructor it overrides the default onChange event(s), since one of these events is updating the hidden which I'm trying to update from it all ends rather disastoursly, is there anyway of adding to an onchange when constructing the slider in the form class? -- View this message in context: http://www.nabble.com/Updating-another-field-on-change-of-a-horizontalSlider-tp24480918p24480918.html Sent from the Zend Framework mailing list archive at Nabble.com.
