Is there a way to store the value of a js variable in a ruby variable? The reason I ask is because, for example, when a google maps api returns the result of let's say the location on the map, it returns it in a js variable. I need to get the value from that variable to be stored in a ruby variable. Is there a way in which I can do that? Thanks.

make an http request to your app (either an ajax request or a more traditional form submission)

Thanks for the idea. I did something like this, but the page keeps reloading over and over:

\<script type="text/javascript"\>

&nbsp;&nbsp;&nbsp;temp = "wechangedit"; &nbsp;&nbsp;&nbsp;window.location.href = "[http://localhost:3000/home/abc](http://localhost:3000/home/abc)? keyword="+temp;

\</script\>

\<%= params[:keyword] %\>
