Press the return key to submit input in the text area without adding a new line

Looking for a solution to submit text entered in a Shiny textarea without using CTRL or CMD? Check out this binding. Pressing return should do the trick, but without adding a newline. A textarea is needed for ample input space without hiding any text.

UPDATE: Currently, the binding works with CTRL-return (or CMD-return). By adjusting lines 18-22 to use only event.keyCode == 13, the input can be submitted without additional keystrokes. However, it still adds a pesky newline character that we want to avoid.

Answer №1

To ensure your function works correctly, be sure to stop the default action of adding a new line before executing it.

if (event.keyCode == 13 && (event.metaKey || event.ctrlKey)) {
    event.preventDefault();
    ...
}

Answer №2

You should consider adding curly braces to the conditional parts of your if statements on lines 28 and 30.

It's possible that this could be causing some problems...
