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