Im trying to grab the ids of the images using rails, pass those ids to javascript and then flip through them using a javascript Image Viewer.
This is what I have in my rails controller
@rails_array = Images.all
this is in my view file
<script type="text/javascript" >
var myIds=new Array(<% @rails_array %>);
</script>
You can collect Ids from controller like this:
@rails_array = Images.all.map &:id
In the View:
<script type="text/javascript" >
var myIds= <%= @rails_array %>
</script>
A good way to pass any object to javascript is through JSON:
var myId= <%= @rails_array.to_json %> ;
Note: You'll need to append .html_safe for strings & hashes (or arrays containing them), but it isn't needed for arrays of integers.
Hi have you tried split() method of javascript
<script type="text/javascript">
var myId=<% @rails_array %>.split(/,/);
</script>
