I am trying to trigger events in force:inputfield which is binded by Sobject lookup.How to identify value change of the field.I tried in two approach:

 <aura:registerEvent name="testEventFired" type="c:testevent"/>
 <aura:handler name="testEventFired" event="c:testevent" action="{!c.func}"/>
 <force:inputfield aura:id="Name" value="{!v.objectfieldbinding}" change="{!e.testEventFired}"/>
  testevent is component event
 <force:inputfield aura:id="Name" value="{!v.objectfieldbinding}"/>
   <aura:handler name="change" value="{!v.name}" action="{!c.func}"/>`

func will trigger a another component event in controller side.I cant able to bind the value of inputfield in handler beacause it is not attribute value

NewEdit: To brief you on the context more I am trying display table with team member based on the account selected in the component my code is here below:

<aura:registerEvent name="componentEventFired" type="c:Callevent"/>
<aura:attribute name="obj" type="csutomobjecttype" default="{ 'sobjectType': 'customobject' }"/>
<force:inputfield aura:id="Account" value="{!v.obj.Accountlookupfield}" change="{!c.evac}"/>
<aura:handler name="componentEventFired" event="c:Callevent" action="{!c.trigaction}"/>
<aura:event type="Component" description="Event template">
<aura:attribute name="display" type="object"/>
controller Js:
evac: function(component,event)
            var  evva=component.find("Account").get("v.value");
            var compEvents = component.getEvent("componentEventFired");
            compEvents.setParams({ "display" : evva });

        trigaction : function(component, event) {
        var context = event.getParam("display");
        var atmaction=component.get("c.getatm");
            atr : context
            //get the response state
            var state = a.getState();
            //check if result is successfull
            if(state == "SUCCESS"){
            } else if(state == "ERROR"){
                alert('Error in calling server side action');
Apex class:
public Id atr {get;set;}
Public static List<AccountTeammember> getatm(string atr){
            List<AccountTeammember> atm = new List<AccountTeammember>();
            atm=[SELECT TeamMemberRole,UserId FROM AccountTeamMember where AccountId =:atr ];  
    return atm;
  • So why we need the event for that, can't we simply move this trigaction controller method to helper and call it from evac? that seems easy to me. – itzmukeshy7 Oct 6 '20 at 2:12

Add change attribute which points to a controller method in the force:inputField component.


<aura:application controller="AccountController" extends="force:slds">
   <aura:attribute name="contact" type="Contact" 
               default="{ 'sobjectType': 'Contact' }"/>
   <force:inputField aura:id="accountLookup" 
                 value="{!v.contact.AccountId}" change="{!c.inputChanged}"/> 


    inputChanged : function(cmp, event, helper) {

FYI, force:inputField is noisy at the moment, you might get some weird errors while using it.

  • inputfield is getting disabled after added fuction to the change attribute.See my edited code above – Vidhyasagaran Muralidharan Jan 6 '17 at 19:08
