I have a form for editing profiles. Rails automatically generates the form id as 'edit_profile_##' where ## is the profile id of the current user(instance variable-@profile_id). I need to use this form id for my javascript functions. Is there a way to get the current user's profile id inside js? Or is there a way I can override the automatic id generation by rails?

you have to send that using function parameter

.html.erb 

<script type="text/javascript">
   var user_id = <%= @profile_id %>; // for integer
   var user_name = '<%= @profile_name %>'; // for string

   abc(user_id)// this is your function in .js file

</script>

.js

 function abc(id){
   alert(""+id)
 }

ok thanks. so thats the only way then? i was trying to see if there was a way without passing it in a function call. coz my js function (see below-submitProfileForm) is actually an event handler which needs to be called only when the form is submitted Event.observe('window','load',function(){ $('edit_profile_##').observe('submit',submitProfileForm); }); –  Sathya Jul 1 '10 at 5:10
    
yes that is the only way you can access instance variable in .js file –  Salil Jul 1 '10 at 5:20

Are you using normal *.html.erb views?

Can't you do something like :

<script type="text/javascript">
    user_id = <%= @profile_id %>;
</script>

?

yes i do use html.erb views. So u mean to say i can include this in my html.erb file? but how do i access user_id inside my .js file? –  Sathya Jul 1 '10 at 4:59
    
I have no idea how you have your js files. But you can create methods and then pass the parameter around, or create a global variable (like in my example, though I really would not recommend that). –  Francisco Soto Jul 1 '10 at 5:37
