javascript - How to get the content of a text area into a js file

Question

I am aware that tis question has been asked before however I am shit at html so I couldn't really apply the answer to my case.

Basically, I would like to get the content of what is written in the textarea in real time so it updates in realtime onto a javascript file. main.html

<textarea type="text" name="keywords" cols="100" rows="100"></textarea> <br />

Thanks in advance!

Answer 1

Try a framework, for example React, Angular, Vue. Whatever fits you best.

Or:

const textarea = document.getElementById('myTextarea')
const currentValue = ''

function update(e) {
   currentValue = textarea.value
}

textarea.addEventListener('keydown', update)
textarea.addEventListener('keyup', update)
