Question

I have a weird problem in some JavaScript code that’s a part of one of my RoR projects. Here’s the code:

alert(<%= params[:browse_view]%>)

<% if params[:browse_view] == true %>
  alert('Changing to browse view...')
  changeToBrowseView();
<% else %>
  alert('Changing to list view...')
  changeToListView();
<% end %>

What’s happening is that the alert at the top will show false, but then the top portion of the if statement will run. This is going to be a remarkably stupid issue, but I have no idea what’s going on…

Answer 1

Are you sure params[:browse_view] is a boolean rather than a string?

I would take a look at the proven ways to parse string values to their corresponding boolean values:
