Hi and thank in advance.
We are migrating to lightning and i have a few javascript buttons to convert.  
Js button "if("{!Account.Account_Status__c}"!="Active Account")
window.alert("You can create an RTO for an active Distributor only.");
else{
window.open

//prepopulate fields.

}"


I created an Aura Component to display a Modal popup.  What I want to do is have an if / else statement

User clicks on Action: New Child record.  If the Account status != Active, display Modal "you can only create child record on Active account.  

If the Account status = Active then proceed with creating a new record.  Then prepopulate some values on the new record.

Component
<aura:component implements="force:lightningQuickAction" >
    <!--Boolean attribute to indicate if modal is open or not 
       default value is false as modal is closed when page is loaded 
    -->
    <aura:attribute name="isModalOpen" type="boolean" default="false"/>
    
    <!--Display modal based on Account status.  If not active, display. Else prepopulate fields 
    -->
    <aura:attribute name="recordId" type="Id" />
    <aura:attribute name = "Account_Status__c" type="String"/>
    <aura:attribute name="passThroughValue" type="String"/>
    
    <lightning:card title="{!v.passThroughValue}">
  
    </lightning:card>
                    
    <div class="slds-m-around_xx-large">
             <div class="slds-modal__content slds-p-around_medium" id="modal-content-id-1">
                        <p><b>
                            You can create an RTO for an active Distributor only.
                            </b>
                        </p>
                    </div>

        <!--Use aura:if tag to display/hide popup based on isModalOpen value-->  
        <aura:if isTrue="{!v.Account_Status__c}">
        <aura:if isTrue="{!v.isModalOpen}">
             
            <!-- Modal/Popup Box starts here-->
            <section role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true" aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">
                <div class="slds-modal__container">
                    <!-- Modal/Popup Box Header Starts here-->
                    <header class="slds-modal__header">
                        <lightning:buttonIcon iconName="utility:close"
                                              onclick="{! c.closeModel }"
                                              alternativeText="close"
                                              variant="bare-inverse"
                                              class="slds-modal__close"/>
                        <h2 id="modal-heading-01" class="slds-text-heading_medium slds-hyphenate">Modal/PopUp Box</h2>
                    </header>
                    
                </div>
            </section>
            <div class="slds-backdrop slds-backdrop_open"></div>
        </aura:if>
            </aura:if>
    </div>
</aura:component>

Controller:
({    
   openModel: function(component, event, helper) {
      // Set isModalOpen attribute to true
      component.set("v.isModalOpen", true);
   },
  
   closeModel: function(component, event, helper) {
      // Set isModalOpen attribute to false  
      component.set("v.isModalOpen", false);
   },
  
   submitDetails: function(component, event, helper) {
      // Set isModalOpen attribute to false
      //Add your code to call apex method or do some processing
      component.set("v.isModalOpen", false);
   }, 
    }   )

Is this possible?
