Change  lt button type  button  to  lt button type  submit   Remove the onClick  Instead do  lt form className  commentForm  onSubmit  this onFormSubmit  gt   This should catch clicking the button and pressing the return key   onFormSubmit   e   gt      e preventDefault      const   name  email     this state       send to server with e g   window fetch           lt form onSubmit  this onFormSubmit  gt           lt button type  submit  gt Submit lt  button gt   lt  form gt

It s been quite a few years since this question was last answered  React introduced  Hooks  back in 2017  and  keyCode  has been deprecated   Now we can write this     useEffect      gt        const listener   event   gt          if  event code      Enter     event code      NumpadEnter             console log  Enter key was pressed  Run your function                callMyFunction                       document addEventListener  keydown   listener       return      gt          document removeEventListener  keydown   listener                      This registers a listener on the keydown event  when the component is loaded for the first time  It removes the event listener when the component is destroyed

import React    useEffect  useRef   from  react    function Example          let inp   useRef        useEffect      gt            if   inp  amp  amp   inp current  return          inp current focus            return      gt  inp   null               const handleSubmit        gt                             return            lt form             onSubmit  e   gt                    e preventDefault                    handleSubmit e                           gt               lt input                 name  quot fakename quot                  defaultValue  quot      quot                  ref  inp                  type  quot radio quot                  style                        position   quot absolute quot                       opacity  0                                  gt               lt button type  quot submit quot  gt                  submit              lt  button gt           lt  form gt           Enter code here sometimes in popups it would not work to binding just a form and passing the onSubmit to the form because form may not have any input  In this case if you bind the event to the document by doing  document addEventListener it will cause problem in another parts of the application  For solving this issue we should wrap a form and should put a input with what is hidden by css  then you focus on that input by ref it will be work correctly

this is how you do it if you want to listen for the  Enter  key  There is an onKeydown prop that you can use and you can read about it in react doc  and here is a  codeSandbox  const App        gt        const something  event   gt            if  event keyCode     13                console log  enter                   return        lt div className  App  gt           lt h1 gt Hello CodeSandbox lt  h1 gt           lt h2 gt Start editing to see some magic happen  lt  h2 gt           lt input  type  text  onKeyDown   e    gt  something e     gt       lt  div gt
