reactjs - How to force Enter key to trigger "submit" function without need to focus an input -

i'm making app in react-redux , want simple feature that's starting tricky implement.

:)

i want able open webapp (i land on login screen) , hit enter (the browser has saved user , password , filled in in correct input fields) , have "enter" keystroke tigger login function without me needing click anywhere first focus something.

(on non-root component)

i've got password input (the last one) bound enter key correctly.

so pressing enter when have password field focused works :

handlesubmit() {     const { authenticate } = this.props;     const { tusername, tpassword } = this.state;     const credentials = {         username: tusername,         password: tpassword,     };     authenticate(credentials); }  _handlekeypress = (e) => {     if (e.key === 'enter') {         this.handlesubmit();     } };  render() {         return (             <div onkeypress={this._handlekeypress} >                 <card id="signin">                     <cardimg top width="100%" src={rubislogo} alt="rubis" />                     <inputgroup>                         <input                             placeholder="nom d'utilisateur"                             value={this.state.tusername}                             onchange={this.updateuser}                         />                     </inputgroup>                     <inputgroup>                         <input                             placeholder="mot de passe"                             type="password"                             value={this.state.tpassword}                             onchange={this.updatepassword}                             onkeypress={this._handlekeypress}                         />                     </inputgroup>                     <div>                     <button                     id="btn"                     onclick={this.handlesubmit}                     to="/home">login                     </button>                     </div>                     <modalpassword class="modal" buttonlabel="mot de passe oublié ?" />                     <modalaccount class="modal" buttonlabel="créer un compte" />                 </card>             </div>);     } 

as can see i've tried putting on div didn't work. don't want solution based on that. want enter-key gobal fallback on view. user can't loose funtionality because clicked somewhere.

set focus div default using tabindex javascript event triggered

render() {         return (             <div onkeypress={this._handlekeypress} tabindex="1" >                 <card id="signin">             ..)}
