Simulate Enter In JavaScript

Question

I try to simulate Enter in JavaScript in a specific TextArea. This is my code:

 function enter1() {
       var keyboardEvent = document.createEvent('KeyboardEvent'); 
       var initMethod = typeof keyboardEvent.initKeyboardEvent !== 'undefined' ? 'initKeyboardEvent' : 'initKeyEvent'; 
       keyboardEvent[initMethod]('keydown', // event type : keydown, keyup, keypress
            true, // bubbles
            true, // cancelable
            window, // viewArg: should be window
            false, // ctrlKeyArg
            false, // altKeyArg
            false, // shiftKeyArg
            false, // metaKeyArg
            13, // keyCodeArg : unsigned long the virtual key code, else 0
            13 // charCodeArgs : unsigned long the Unicode character associated with the depressed key, else 0
       );
       document.getElementById('text').dispatchEvent(keyboardEvent);
 }

TextArea:

<textarea id="text"> </textarea>

When I call enter1(), it doesn't do anything in the TextArea. Why is this?

Answer 1

For anyone that has a problem dispatching the event, try adding the key-value pair bubbles: true:

const keyboardEvent = new KeyboardEvent('keydown', {
    code: 'Enter',
    key: 'Enter',
    charCode: 13,
    keyCode: 13,
    view: window,
    bubbles: true
});
