` Can we use lightning design resource for mapping? I want to bind the apiName dynamically so what I am doing is like,

So at the time of component placement on a page from app builder, I have given input for TitleApi = FirstName so its not inserting data for FirstName. Can we use such a syntax like value="{!v.conInfo+'.'+v.TitleApi}"to make api name dynamic.

This is possible, but not via a direct binding in the component markup.

A couple of the options in JavaScript to achieve this are...

Generic object

  • Create a new attribute that is of generic Object type and bind this to the inputText component e.g. {! v.tempObj.value }

  • Add a change handler for the new Object attribute, and then in JavaScript update your Contact attribute with whatever was set, e.g. component.set("v.conInfo." + component.get("v.TitleApi"), component.get("v.tempObj.value"));

or...

Dynamic inputText creation

  • On init of your component, create the inputText component dynamically using $A.createComponent(). This will allow you to bind the inputText directly to the correct field on Contact.

  • Thanks. for more clarification, my requirement is like I have already working component I am taking some inputs while placement of the component in-app builder through design resource. And inputs are nothing but field API names so I want to replace it like value={!v.objRef.fieldName1} to -----> value={!v.objRef.fieldName2} where I will provide input for fieldName2 through design resource

  • Yep, understood. The second option in my answer is probably best for your use case. Click the link in my answer to view the documentation for $A.createComponent(). You can create the ui:inputText component and bind it to whatever field the admin entered in App Builder.
