I have a number of <lightning:select> components in an iteration like so:

<aura:iteration items="{!v.data}" var="obj">
    <div class="slds-grid">
        <div class="slds-size_1-of-2">
        <div class="slds-size_1-of-2">
            <lightning:select name="{!obj.Id}" value="{!obj.Role}" onchange="{!c.changeRole}">

Each of these deals with a particular record, so when a change is made, I need to know the Id, as well as the new value of the select. My method:

changeRole: function(component, event, helper) {
    var val = event.getParam('value');
    val id = event.getParam('name');

...ends up printing "undefined-->undefined" to the console every time.

I know that the prescribed method of getting these values is to use component.find('aura-id').get('v.value'), but that requires my selects to be static, not dynamic. I also know that I've successfully used getParam in similar situations in the past.

How can I get the values I need?


You can try to use event.getSource()

changeRole: function (component, event, helper) {
   const value = event.getSource().get('v.value');
   const name = event.getSource().get('v.name');
