Get particular value from json string in Aura component

apexaurajsonlightning-aura-components

I have below code where I am converting json.stringify and getting below output

let theData = JSON.stringify(helper.getData(component));
console.log('theData>>>' + theData);

output:

{"userName":"[email protected]","profile":"Sales","Account":"Self","Contact":"Personal","Time":"IST"}

I need to get profile value in one var/let, but I am not able to understand how I can get the specific value.

I tried this but not working

var Profile = theData[0].get('profile'))

getting error. Please help

first you don't need to do JSON.stringify because its returning object.
so you can simple get profile value using below code

let theData =helper.getData(component);
console.log(theData.profile);

second way:

let theData = JSON.stringify(helper.getData(component));
let output = JSON.parse(theData);
console.log(output.profile);

Hope its help

create an aura:Attribute in your event, which you should pass while invoking the event

Aura attribute in event -

<aura:attribute name="sObjectId" type="Id" required="true" description="The Id of the selected SObject." />

While invoking event - var updateEvent = cmp.getEvent("eventName");

// Populate the event with the selected Object Id
updateEvent.setParams({
    "sObjectId" : value
});

In the event handler's action write following -

// Get the Id from the Event
var accountId = event.getParam("sObjectId");

Hope this helps :)

String str = '{johny:[1,2,3,4,5],erich:[5,6,7,8,9],}';
system.debug('strValue: ' + str.left(str.length()-2)+str.right(1));

yields

strValue: {johny:[1,2,3,4,5],erich:[5,6,7,8,9]}
