Question

Is it possible to disable spellcheck in a textarea via JavaScript?

I've been looking at the HTML5 'spellcheck' attribute, and I can get it to work on its own. However, I'd like to be able to change this attribute via JavaScript.

After reading the documentation provided at the above link, I put together the following lines of code (snippets from a larger file; I know they won't work on their own):

document.querySelector("#editor").spellcheck = "false";

and

document.querySelector("#editor").spellcheck = "true";

But it doesn't seem to work. Have I made a mistake or misunderstood the documentation? (Unhelpfully, the JavaScript console in Google Chrome is not returning an error.) Or is there any other way to go about doing this?

Answer 1

You are setting it to the String "true" (which is a true value) and to the String "false" (which is also a true value).

Use Booleans, not Strings. Get rid of the quotes.
