Clear Button

Using Rails 4. I have a text_area_tag with submit_tag to do a query. I
need to add a button to clear out the textarea and resubmit the form
(using form_tag)

Layout looks like this:
Query Button 1 Clear Button

Code looks like this:
form_tag ....
    submit_tag "Query Button"
end form tag

Any ideas? Ajax was suggested.

?! Why would you want to submit an empty form?

Regardless, just create another submit button with an onsubmit
handler to set the textarea value to "".

But I still can't imagine your use case...
