Javascript – Is it possible to trigger a mui dialog actions button with CTRL + S?

Is this possible to do?

    You can accomplish this using keycodes.

    Note that you might want to consider COMMAND+S for macOS users aswell.

    function checkForInput(e) {
      var evtobj = window.event? event : e
      if (evtobj.keyCode == 83 && evtobj.ctrlKey) console.log("Pressed CTRL+S")
}

document.onkeydown = checkForInput;

    In a typical Material-UI (MUI) application, the dialog actions button is usually triggered by clicking on it with a mouse or tapping on it on a touch-enabled device. However, you can customize the behavior of your MUI dialog to respond to keyboard events, including CTRL + S, by using JavaScript event listeners.

    import React, { useState } from ‘react’;

    import Button from ‘@mui/material/Button’;

    import Dialog from ‘@mui/material/Dialog’;

    import DialogActions from ‘@mui/material/DialogActions’;

    import DialogContent from ‘@mui/material/DialogContent’;

    import DialogContentText from ‘@mui/material/DialogContentText’;

    import DialogTitle from ‘@mui/material/DialogTitle’;

    function App() {

    const [open, setOpen] = useState(false);

    const handleOpen = () => {

    setOpen(true);

    };

    const handleClose = () => {

    setOpen(false);

    };

    const handleKeyDown = (event) => {

    // Check if CTRL + S is pressed (event.ctrlKey) and the 's' key (event.key)

if (event.ctrlKey && event.key === 's') {

  // Trigger the action you want here, e.g., close the dialog

  handleClose();

}

    };

    // Attach the event listener to the document when the dialog is open

    React.useEffect(() => {

    if (open) {

  document.addEventListener('keydown', handleKeyDown);

} else {

  document.removeEventListener('keydown', handleKeyDown);

}

    }, [open]);

    return (

    <div>

  <Button variant="outlined" onClick={handleOpen}>

    Open Dialog

  </Button>

  <Dialog open={open} onClose={handleClose}>

    <DialogTitle>Dialog Title</DialogTitle>

    <DialogContent>

      <DialogContentText>

        Press CTRL + S to trigger the action.

      </DialogContentText>

    </DialogContent>

    <DialogActions>

      <Button onClick={handleClose} color="primary">


        Cancel

      </Button>

      <Button onClick={handleClose} color="primary">

        Save

      </Button>

    </DialogActions>

  </Dialog>

</div>

    );

    }

    export default App;

    We use the handleKeyDown function to listen for keyboard events on the document when the dialog is open. When CTRL + S is detected, it triggers the desired action (in this case, closing the dialog). Make sure to attach and detach the event listener appropriately to avoid unwanted behavior when the dialog is closed.
