Could you please help me and describe how can I able to change the style of switchbutton in readonly mode.
Switchbutton declared as:
<input class="easyui-switchbutton" value="1" name="hours_7" id="hours_7" 
            data-options="onText:'Да',offText:'Нет'">
<style>
    .switchbutton-readonly {
        opacity: 0.5;
        filter: alpha(opacity=50);
    }
</style>
not working
