Occurs before a new slide is added to the SlideBar.
| Param | Type | Details |
|---|---|---|
| e | Object | An event object which contains the slide |
This event can be handled by binding the 'slideadding' event to the SlideBar widget object.
Supported in: v1.0.
An example explaining how to create a handle to the slideadding event in SlideBar widget.
By handling this event you can prevent adding of slide depending on some custom conditions. By returning a false value, you can cancel this event. Whenever the 'Add Slide' button is clicked a new slide is added, until SlideBar contains 4 slides. Afterwards, additional slides can't be added.
$(document).ready(function() {
// Create an instance of SlideBar widget
var $bar = $('#slidebar').slidebar({
slideWidth: 250,
slideHeight: 150
});
// Get the number of present slides in SlideBar
var getSlideCount = function(){
return $bar.slidebar("getList").length + 1;
}
// Create a new slide with its header title
var createNewSlide = function(){
return { content: "<div class="slide"><span>Slide " + getSlideCount() + "</span></div>" };
}
// When 'Add Slide' button is clicked, add a new slide to the SlideBar
var add = function(){
var slide = $bar.slidebar("addSlide", createNewSlide());
}
// Create a handler to the slideadding event and allow SlideBar to contain only 3 slides
$bar.on({
"slideadding": function(e){
var slideCount = getSlideCount() - 1;
if (slideCount > 4)
return false;
});
});
