Hi,

Do this by making this call in the section of your .rhtml page.
<%= javascript_include_tag “Name Of Javascript” %>

I thik this will resolve your problem.

Thanks for your help,
but i already included that… my problem is to return the Javascript
variable in a ruby variable…

Cause Javascript is executed on Client side, so i don t see how to get
back the content of that variable later in the ruby code

I hope to be clear…

thanks

Maybe you should include some more context regarding your problem.
There are many ways to send client information to the server…you
could send this along as part of a form POST, or in the query part of a
URL, or using XMLHttpRequest, or…

You have to send it back somehow. A hidden field in a form, a
parameter in the URL, Ajax, …

You’ll typically write JavaScript code to hook into the new request
to add the value of the variable when the request starts. For
instance, if there’s a form some code in onsubmit sets the hidden
field to the value of the variable at that moment. You see the idea.

So there it is…

I ve got some javascript in a view (a part of the view code)… this
javascript has a variable TOTO…
At the end of the javascript execution in the view, this variable TOTO
contain information that i need later…

So to use this information later, i need to put the content of the
Javascript variable TOTO in a new ruby variable…

how do you do that ?

thanks again

I think what other people have already said. Put your variable inside a
hidden text field or someplace else in the dom and then read it out of
it
with an AJAX call. There’s multiple possibilities for getting the value
with something like that.
