Occurs before a new group is added to the Accordion.
| Param | Type | Details |
|---|---|---|
| e | Object | An event object which contains the group |
This event can be handled by binding the 'groupadding' event to the Accordion widget object.
Supported in: v1.0.
An example explaining how to create a handle to the groupadding event in Accordion widget.
By handling this event you can prevent adding of group depending on some custom conditions. By returning a false value, you can cancel this event. Whenever the 'Add Group' button is clicked a new group is added, until Accordion contains 3 groups. Afterwards, additional groups can't be added.
$(document).ready(function() {
// Create an instance of Accordion widget
var $bar = $('#accordion').accordion();
// Get the number of present groups in Accordion
var getGroupCount = function(){
return $bar.accordion("getList").length + 1;
}
// Create a new group with its header title
var createNewGroup = function(){
return { text: "Group" + getGroupCount() };
}
// When 'Add Group' button is clicked, add a new group to the Accordion
var add = function(){
var group = $bar.accordion("addGroup", createNewGroup());
}
// Create a handler to the groupadding event and allow Accordion to contain only 3 groups
$bar.on({
"groupadding": function(e){
var groupCount = getGroupCount() - 1;
if (groupCount > 3)
return false;
});
});
