Define tools with an array.

$('#tt').tabs({
	tools:[{
		iconCls:'icon-add',
		handler:function(){
			alert('add')
		}
	},{
		iconCls:'icon-save',
		handler:function(){
			alert('save')
		}
	}]
});

Define tools with an existing DOM container.

$('#tt').tabs({
	tools:'#tab-tools'
});
<div id="tab-tools">
	<a href="#" class="easyui-linkbutton" plain="true" iconCls="icon-add"></a>
	<a href="#" class="easyui-linkbutton" plain="true" iconCls="icon-save"></a>
</div>

$('#tt').tabs({
  onBeforeClose: function(title){
	return confirm('Are you sure you want to close ' + title);
  }
});
// using the async confirm dialog
$('#tt').tabs({
  onBeforeClose: function(title,index){
	var target = this;
	$.messager.confirm('Confirm','Are you sure you want to close '+title,function(r){
		if (r){
			var opts = $(target).tabs('options');
			var bc = opts.onBeforeClose;
			opts.onBeforeClose = function(){};  // allowed to close now
			$(target).tabs('close',index);
			opts.onBeforeClose = bc;  // restore the event function
		}
	});
	return false;	// prevent from closing
  }
});

// add a unselected tab panel
$('#tt').tabs('add',{
	title: 'new tab',
	selected: false
	//...
});
// insert a tab panel to the index 2
$('#tt').tabs('add',{
	title: 'inserted tab',
	index: 2
})

var tab = $('#tt').tabs('getSelected');
var index = $('#tt').tabs('getTabIndex',tab);
alert(index);

// update the selected panel with new title and content
var tab = $('#tt').tabs('getSelected');  // get selected panel
$('#tt').tabs('update', {
	tab: tab,
	options: {
		title: 'New Title',
		href: 'get_content.php'  // the new content URL
	}
});

// call 'refresh' method for tab panel to update its content
var tab = $('#tt').tabs('getSelected');  // get selected panel
tab.panel('refresh', 'get_content.php');

Code example:

$('#tt').tabs('enableTab', 1);	// enable the second tab panel
$('#tt').tabs('enableTab', 'Tab2');	enable the tab panel that has 'Tab2' title

Code example:

$('#tt').tabs('disableTab', 1);	// disable the second tab panel.

Code example:

// scroll the tab header to left
$('#tt').tabs('scroll', 10);
