# Which Button Was Pressed?

To find out which button was pressed in a component containing multiple buttons, use `Component.getLocalId()`.

Let’s look at an example with multiple `lightning:button` components. Each button has a unique local ID, set by an `aura:id` attribute.

```nolang
<!--c:buttonPressed-->
<aura:component>
    <aura:attribute name="whichButton" type="String" />
    
    <p>You clicked: {!v.whichButton}</p>

    <lightning:button aura:id="button1" label="Click me" onclick="{!c.nameThatButton}"/>
    <lightning:button aura:id="button2" label="Click me too" onclick="{!c.nameThatButton}"/>
</aura:component>
```

Use `event.getSource()` in the client-side controller to get the button component that was clicked. Call `getLocalId()` to get the `aura:id` of the clicked button.

```javascript
/* buttonPressedController.js */
({
    nameThatButton : function(cmp, event, helper) {
        var whichOne = event.getSource().getLocalId();
        console.log(whichOne);
        cmp.set("v.whichButton", whichOne);
    }
})
```

In the client-side controller, you can use one of the following methods to find out which button was clicked.

-   `event.getSource().getLocalId()` returns the `aura:id` of the clicked button.
-   `event.getSource().get("v.name")` returns the `name` of the clicked button.
