Setting options runtime (changing options dynamically)

There are two ways to modify options after initalization

  1. Using the option method.

    The option method always triggers reinitialization. Most of the settings can be updated only this way, updating without initialization has no effect, because the markup is already generated. If the scroller was visible, the reinitialization hides it and it's not shown again automatically (except in inline display mode).

    Javascript
    // Modify options
    mobiscrollInstance.option({ 
        theme: 'ios', 
        lang: 'de'
    });
    HTML
    <input id="mobiscroll"/>
  2. Modify directly the settings object.

    Useful when changing dynamic settings, which do not need redraw (e.g. readonly, calendar marked days).

    // Modify a setting
    mobiscrollInstance.settings.readonly = true;
    
    // Modify settings in an event
    mobiscroll.image('#mobiscroll', {
        onBeforeShow: function (event, inst) {
            inst.settings.readonly = true;
        }
    });
