javascript - How do you refresh js variables after loading a new partial in RoR? -

in javascript file, pull off rails variable view:

this.main_id = <%= images[0].id %>; 

then use ajax load partial portion of page (the view in question):

var url = '/images/thumbnails_newest/'+ this.main_id; new ajax.updater(this.scroller, url); 

now js variable this.main_id has changed... don't know how access rails variable in partial... update value.

this.main_id = this.main_id in partial.

is there way this? thanks.

add these line @ end of partials

<script> this.main_id=<%=images[0].id%>; </script>

or define js method can set value of this.main_id , takes 1 paramerter image_id , call @ end of partial assume js method name set_main_id call @ of partial code below

<script> set_main_id(<%=images[0].id%>); </script>

actually code in script tag run on client side, client have previous content when new content come js update previous one. hope you.
