submit_tag with javascript function

Question

I am new to rails.I want to call a javascript function when click the submit button.I used submit_tag , but the function did not get triggered.I want some thing like the following ,

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

I googled the problem but I couldn't find a solution.Please any one give a solution.

Answer 1

try onclick

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

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

Answer 2

You can use something like this on the form tag

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