I have an apex method which is returning map in the form of Map<string,Object> and map will contains only one record

Can anyone help me how can I set attribute on component from map value

On component, I have two string attributes string1 and string2

From Java script, I want to set


doInit : function(component, event, helper) {
    //sai start
    var action = component.get('c.showSearch');
    action.setCallback(this, function(response) {
    var state = response.getState();
    if(state === 'SUCCESS') {
        var result = response.getReturnValue();
            component.set('v.searchHub', response.getReturnValue().Search_Hub_Name__c);
    } else {
        console.log('Error: ' + response.getError());

Can anyone help on this please

  • Log the map in the browser's console so I can understand how the map is formed. Commented Mar 28, 2023 at 6:13
  • I have added apex class code in question which is creating map

Why return a map if you only need to return one object?

Assuming there's a good reason for returning a map:

An Apex Map should become a standard Javascript object when it arrives at the front end.

To access it, if you know the name, you can get the object out of the map like this:

let accessPermissionObj = yourResultObject['Access_Permission'];

Now you have the object, you can access the fields as you were before:


If you don't know the key of the map, you can iterate like so:

Object.keys(yourResultObject).forEach(obj => {
  //do something with your object
  //you'd normally put this object in an array or apply a map function

If you wanted to return just one object, your Apex method would look like:

public static Coveo_Similar_Search__mdt showSearch(){}

this would be the result of your Aura server call. And you'd just use the result directly:

var result = response.getReturnValue();

component.set('v.string1', result.Hub_Name__c)
component.set('v.string2', result.Visualforce_Name__c)
  • thanks for helping out here, if I return object instead of map then how can I assign object field to attributes
