Answer 1

You can try

<%= submit_tag , :onclick => "return validateform()" %>

OR

You can Use button_to_function

<%= button_to_function "Greeting", "validateform()" %>

And in your Javascript function, if all the validations pass, submit the form.

Answer 2

You would do it in the form_tag...

<%= form_tag({:action => :whatever}, {:onSubmit => 'return validateform();'} ) %>

Answer 3

try onclick

<%= submit_tag , :onclick => "return validateform();" %>

or if you want to use onsubmit you can use that in your form_tag.

Answer 4

You can use something like this on the form tag

 <% form_for :bla, :html => { :onsubmit => 'blahblah;' } do |f| %>
