Please help me here.
Here is my code for reference, since the actionFunction returns only Pagereference or Void, how can I return the value of function to the next function.

<apex:component controller="EXP_DeleteRowActionController" allowDML="true">
    <apex:form>
        <apex:actionFunction action="{!doCheckBeforeDelete}" name="doCheckBeforeDelete" />  
        <apex:actionFunction action="{!deleteRecord}" name="deleteRecord" />
    </apex:form>

    <script>
function handleConfirm() {
            try{
                //I need some logic like this
                //If doCheckBeforeDelete() return true then execute deleteRecord()
                //Here my problem is actionFunction returns only PageReference or Void
                deleteRecord();
            }catch(error){
                myToast();
            }
            
        }
        function myToast(){
            sforce.one.showToast({
                    'title':'zonex',
                    'message':'test',
                    'type':'warning'
                });
        }
    </script>
    </apex:component>

Thanks,
James
