Question

I have a textarea in a html form and I would like to have a button to add a big black dot character (•) (is this called a bullet?) into this textarea. is it possible in javascript?

Also it needs to be a UTF8 character.

Thanks for your help!

Answer 1

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

See a live demo.

For the sake of keeping things simple, I haven’t written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.
