enter image description here When I have changed value of "Case Type" picklist, Request Detail section is to appear on change of picklist value

I want to show this section on load of this edit page. I am using following code.

<aura:handler name="init" action="{!c.doInit}" value="{!this}"/>

 <lightning:inputField fieldName="Type" aura:id ="caseTypeId" onchange="{!c.caseTypeChange}"/> 

<aura:if isTrue="{!v.caseTypeValue =='Requests'}"> 
                      <h3 class="slds-section-title--divider">Request Details</h3>
                      <div class="slds-grid">
                        <div class="slds-col">
                               <lightning:inputField fieldName="Description" />
                        <div class="slds-col">
                               <lightning:inputField fieldName="Subject" />

component code

doInit: function(component, event, helper) {
    //Edit Case
    helper.caseTypeChangeHelperFun(component, event);                        
},  caseTypeChange : function(component, event, helper) {        
   helper.caseTypeChangeHelperFun(component, event);

Helper Code

 caseTypeChangeHelperFun: function(component, event){               
         var caseTypeIdValue=component.find("caseTypeId").get("v.value");  
         component.set("v.caseTypeValue", caseTypeIdValue);      


  1. When I click on the 'case Type' pick list "request detail" section is showing perfectly.

  2. When I load the "Edit" page and if value is selected as "request" the related section is not showing. This is the problem.

  • can you update your question with where you want clarification? I mean, is there any parent component or child or any other condition? Your input field is defined in which component? – sanket kumar Aug 24 '18 at 8:19

You can access aura:id value like this :

 var caseTypeidValue=component.find("caseTypeId").get("v.value"); //here you will the value

  • I want to access this value at "init" method not for on change event of lightning component, Yes you are right we can access value by this code but for the same component calling only – Sanjay Aug 24 '18 at 7:14
  • Keep that code in doInit.If you have value Input field you will get the value ,otherwise you will get undefined value – Annappa PH Aug 24 '18 at 7:37
  • Output: ----caseTypeId------undefined, when I put this in init method it returns "undefined", Please suggest some thing here to me – Sanjay Aug 24 '18 at 7:52

By this way, you will get value in init method.

Please add this in lightning component 
<lightning:inputField fieldName="Type" aura:id ="caseTypeId" id="caseTypeId1" value="10"/>   
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

    doInit: function(cmp) {
        var caseTypeidValue=cmp.find("caseTypeId").get("v.value");

  • because in the code snippet you have once: 'cmp' and 'component.find'. Both have to be the same. So just change cmp in the doInit function to component – utm Aug 24 '18 at 8:06
  • As there is no value parameter, it is showing undefined. I have changed inputField declaration. It is accessible now. – Dhanik Lal Sahni Aug 24 '18 at 8:12
  • I was already changed 'cmp' with 'component' but i was getting the same issue – Sanjay Aug 24 '18 at 8:24
  • you have to put value attribute also in lightning:inputField field. as you are not adding that attribute, it is showing undefined. If you add that it will work. – Dhanik Lal Sahni Aug 24 '18 at 8:27
