Create a Standard Page with the name “Sample”:

Sample code:

Component1 cmp:

<aura:component implements="forceCommunity:availableForAllPageTypes" access="global" >  
    <aura:attribute name="Txt1" type="String" default=""/>  
    <aura:attribute name="Txt2" type="String" default=""/>  
    <div class="slds-box slds-theme_default">  
        This is component 1.<br/><br/>  
        <lightning:input type="text" value="{!v.Txt1}" label="Enter some text"/><br/>  
        <lightning:input type="text" value="{!v.Txt2}" label="Enter some text"/><br/>  
        <lightning:navigation aura:id="navService"/>  
        <lightning:button label="Navigate" onclick="{!c.navigateToComTwo}"/>  
    </div>  
</aura:component> 

Component1 JavaScript Controller:

({  
      
    navigateToComTwo : function( component, event, helper ) {  
          
        event.preventDefault();  
        var navService = component.find( "navService" );  
        var listVars = [];
        listVars.push( component.get( "v.Txt1" ) );
        listVars.push( component.get( "v.Txt2" ) );
        var pageReference = {  
            type: "comm__namedPage",  
            attributes: {  
                pageName: "sample"  
            },  
            state: {  
                sampleVar: listVars 
            }  
        };  
        sessionStorage.setItem( 'pageTransfer', JSON.stringify( pageReference.state ) );  
        console.log( 'State is ' + pageReference.state );
        navService.navigate( pageReference );  
          
    }  
      
}) 

Component2 cmp:

<aura:component implements="forceCommunity:availableForAllPageTypes" access="global" >  
    <aura:attribute name="Texts" type="String[]" default=""/>  
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>  
    <div class="slds-box slds-theme_default">  
        This is component two.<br/><br/>  
        Texts are <br/>
        <aura:iteration items="{!v.Texts}" var="obj">
            {!obj}<br/>
        </aura:iteration>
    </div>  
</aura:component> 

Component2 JavaScript Controller:

({  
      
    doInit : function( component, event, helper ) {  
          
        var resultMsg = sessionStorage.getItem( 'pageTransfer' );  
        
        if ( resultMsg ) {
            
            console.log( 'resultMsg is ' + JSON.parse( resultMsg ).sampleVar );
            component.set( "v.Texts", JSON.parse( resultMsg ).sampleVar );  
            
        }
          
    }  
      
})
