Aruna Vasahan Lightning Component: Passing parameter to Server side controller
Hi guys,
I'm now working with a community based on Napili template. Here my task is to fetch the record id from the record page and to display the details of the record in a separate page. I've wrote some coding for it but Since I'm new to lightning concept I'm not able to achieve this. I have given my code below.
I want to pass the fetched record Id to the apex class and to display the record dtails using SOQL query.Please help me in accompolishing my task.
Thanks and Regards
Aruna

I've gone through the code and looks like you have not called the echo function
COMPONENT: <aura:component controller="ParamController" implements="force:lightningQuickAction,force:hasRecordId”> <AURA:HANDLER NAME="INIT" VALUE="{!THIS}" ACTION="{!C.DOINIT}" /> <aura:attribute name="recordId" type="String" default="___"/> Record Id is {!v.recordId} <ui:button label="Call server" press="{!c.echo}"/> </aura:component>
COMPONENT CONTROLLER:
({ doInit : function(cmp,event,helper){ var recordId = cmp.getParam("v.recordId"); // console.log("Current Record Id: " + attributeValue); // var target = event.getSource(); //cmp.set("v.recordId", target.get("v.recordId")); var action = cmp.get("c.serverEcho"); action.setParams({ recordId : cmp.get("v.recordId") }); action.setCallback(this, function(response) { var state = response.getState(); if (state === "SUCCESS") { alert("From server: " + response.getReturnValue()); } //else if (cmp.isValid() && state === "INCOMPLETE") { else if (state === "INCOMPLETE") { // do something } //else if (cmp.isValid() && state === "ERROR") { else if (state === "ERROR") { var errors = response.getError(); if (errors) { if (errors[0] && errors[0].message) { console.log("Error message: " + errors[0].message); } } else { console.log("Unknown error"); } } }); $A.enqueueAction(action); } })
