Using mainly bulma and react to make a page of sorts, im looking to call the Begintransaction function in order to open a modal. Im not sure what im doing wrong with the syntax as it seems to be in order but obviously not

import'bulma/css/bulma.css'
import { useRef } from "react"


    
 export default function MainMenu() {
    
      
        const inputRef = useRef(null);
        return (

            
            
        
        function BeginTransaction(
                            inputRef.current.classList.add("is-active")
                      )

        

            <html>
  
                  <body>
                  <div class="modal" ref ={inputRef} id = "WalletEntry">

                  </body>
            </html>
      )}

Im trying to call a modal with a ref to activate it the modal in question is made at the top of the body.

>Solution :

You put the body of the function inside the parameters.

Also, that function should be moved before the return and switched to an inline function

const inputRef = useRef(null);

const BeginTransaction = () => {
    inputRef.current.classList.add("is-active")
};

return (
    /* your elements here */
);
