Question

I have a rails app in which I would like only one view to be refreshed every five seconds. I put the following in assets/javascripts/application.js

function timedRefresh(timeoutPeriod) {
    setTimeout("location.reload(true);",timeoutPeriod);
}

$(document).ready(function(){
  timedRefresh(5000);
});

However this will cause every view to be refreshed every five seconds. How could I make this JavaScript apply to only one view?

(using Rails 3.2.5)

If you want to keep your JS in application.js you can simply check for the presence of a specific element and act accordingly. For example:

some_vew.html.erb

<div id = "refreshable">
    <!-- So on and so forth... -->
</div>

application.js

$(function() {

    // function timeRefresh()...

    if ($('#refreshable').length) {
        timedRefresh(5000);
    }
});
