ui:menuSelect

Indicates that a menu item has been selected in the menu component.

For example, the ui:menuList component registers this event so it can be fired by the component.

1<aura:registerEvent name="menuSelect"  type="ui:menuSelect"
2                    description="The event fired when a menu item is selected." />

You can handle this event in a ui:menuList component instance. This example shows a menu component with two list items. It handles the ui:menuSelect event and click events.

1<ui:menu>
2    <ui:menuTriggerLink aura:id="trigger" label="Contacts"/>
3        <ui:menuList class="actionMenu" aura:id="actionMenu" menuSelect="{!c.selected}">
4            <ui:actionMenuItem aura:id="item1" label="All Contacts" 
5                               click="{!c.doSomething}"/>
6            <ui:actionMenuItem aura:id="item2" label="All Primary" 
7                               click="{!c.doSomething}"/>
8        </ui:menuList>
9</ui:menu>

When a menu item is clicked, the click event is handled before the ui:menuSelect event, which corresponds to doSomething and selected client-side controllers in the following example.

1({
2    selected : function(component, event, helper) {
3        var selected = event.getParam("selectedItem");
4        
5        // returns label of selected item
6        var selectedLabel = selected.get("v.label"); 
7    },
8    
9    doSomething : function(component, event, helper) {
10        console.log("do something");
11    }
12})
