I have an attribute in lightning component:
<aura:attribute name="pricingRecommendationListDetailsData" access="PUBLIC" type="list" default="object[]" />
Data stored in it visible as:
{accRecmId: "a07e000", category: "test", Price: 56, PriceRange: {…}, cost: 0.3, …}
Now I need to pass this attribute as parameter to apex controller on button click.And I need to iterate over values such as accRecmId in apex class
you have two option:
JS Controller:
var selectedList = component.get('v.pricingRecommendationListDetailsData');
var ids=new Array();
for (var i= 0 ; i < selectedList.length ; i++){
ids.push(selectedList[i].accRecmId);
}
var idListJSON=JSON.stringify(ids);
var action = component.get("c.callServier");
action.setParams({
"accRecmId":idListJSON
});
Apex Controller:
public static void callServier(String accRecmId) {
Type idArrType = Type.forName('List<string>');
List<string> wrapperList = (List<string>) JSON.deserialize(accRecmId, idArrType);
}
var ids = selectedList.map(value => value.accRecmId); There's usually a shorter way than a for(...) loop in modern JS.
My recommendation is to prepare the required data on the client and send only the list of ids you have to work within the server:
MyComponentController.js
// get the list of pricing details
var pricingDetails = component.get('v.pricingRecommendationListDetailsData');
// map through the list to create a list of acc rec ids
var accRecmIds = pricingDetails.map(function (detail) {
return detail.accRecmId;
});
// get the server call action
var action = component.get("c.iterateOverAccRecmIds");
// set the list of acc rec ids as a parameter
action.setParams({
"accRecmIds":accRecmIds
});
MyComponentController.cls
public with sharing class MyComponentController {
@AuraEnabled
public static void iterateOverAccRecmIds(List<String> accRecmIds) {
// do what you want with the list of ids...
}
}
accRecmIdfrom each instance?
