Question

I’m using rails version 3.2.6 and I’m trying to pass a Javascript variable to another page “Test10”. I have the following code in the view:

<script>
var message = "hello world!";
</script>

<%= link_to "Go!", Test10_path(), :with => "'message='+ message"  %>

The parameter is not passed to Test10. I have the following in the Test10 controller:

def Test10
  @hello = params[message]
end

Is this the right way to pass a Javascript variable to my rails controller? It is not working. I’d appreciate any pointers. Thanks!

Answer 1

<%= link_to "Go!", Test10_path(), :id => "my_link"  %>


<script>
    var message = 'test';
    var url = $('#my_link').attr('href') + '?message=' + message;
    $('#my_link').attr('href', url);
</script>

Something like this should work. Although most of the time, it’s best to pass params by using forms instead …
