Get the page from where the button is clicked

Question

The New standard button in the Salesforce is overriden by the Lightning component (Aura). Now this New button is being used in the multiple places:

1. While creating a contact record from the list view of contacts:

2. Creating a contact from the Account related list:

In #2, I want the Account lookup field to be populated automatically when clicking on the NEW button. Below is the form that I have built using Lightning component.

My question is that - How do we identify the page where this contact button is getting clicked? With the help of the page reference or if I get the RecordId where the button is clicked, I can populate the Acccount field in the component.

I tried using the document.referrer but that is not serving me with the intended results that I need.

Answer 1

variables need to be append with c__ to use it on aura cmp.
You can create List Button with Contenr Source URL & pass accountId variable as below:

/lightning/cmp/c__AuraCMPNameHere?c__accountId={!Account.Id}
(Note. Don't add any url function or quotes in above button url)

Now in your Aura Cmp js file you've add doint function which will run when cmp loads & take variable values from pageRef state.

AuraCMPNameHere.cmp
<aura:component implements="flexipage:availableForAllPageTypes,force:hasRecordId,lightning:actionOverride,lightning:isUrlAddressable" access="global" description="some description here">
    <aura:handler name="init" action="{!c.doInit}" value="{!this}"/>
    <!--
        //cmps
    -->
</aura:component>


AuraCMPNameHere.js
({
    doInit: function(component, event, helper){
        var myPageRef = component.get("v.pageReference");
        var accountId = myPageRef.state.c__accountId;
        //do something with your accountId variable
    }
})

Now you can assign this accountId variable as per your requirement.
