Having more than one submit_tag call the same javascript function

Hello,

I have a Ruby-on-Rails web application in which I need to have more than one submit_tag (or any type of button) call the same function - WITHOUT having to do an actual submit.

I can do this with one submit_tag like so...

<% submit_tag "Call JS Function", :id => "call_js_function" %>

  $j('#call_js_function').click(function()
  {          
    //Do stuff - function is indeed called
    return false;
  });    

However, this doesn't work with more than one submit_tag - since I can't give two submit_tags the same ID.


So, I though maybe onclick might work.  So far, I've seen dozens of examples of how to user onclick; none of them have actually worked - although maybe I'm just not using it correctly.

I create my javascript function like so...

$j(function javascript_function()
{
  //try to do stuff here - but it never gets executed
  return false;
}

And I try to call it using the onclick attribute.  However, none of these seem to work:

<%= submit_tag "Call JS Function", :onclick => "$j(javascript_function())" %>
<%= submit_tag "Call JS Function", :onclick => "javascript_function()" %>
<input type='submit' value='Call JS Function' onclick='javascript_function()'/>

So far, none of these work.

Any suggestions?

Thanks in advance,
Tim

can try

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

You can Use button_to_function

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