Question

I’m trying to use the pageless jquery plugin and in my application helper I need to pass the name of the callback function as one of the parameters:

opts = {
        :totalPages => total_pages,
    :url        => url,
    :loaderMsg  => 'Loading more items...',
    :loaderImage => image_path("img/ajax_loader.gif"),
    :complete => "update"
}

javascript_tag("$('#tiles').pageless(#{opts.to_json});")

This doesn’t work apparently because jquery tries calling “update”.call()

How should I pass the name of my callback function so in json it’ll be without quotations

Answer 1

You want to do something like this:

<%= javascript_tag do %>
  $('#tiles').pageless({
    totalPages: <%= total_pages %>,
    url: '<%= url %>',
    loaderMsg: 'Loading more items...',
    loaderImage: '<%= image_path("img/ajax_loader.gif") %>',
    complete: update
  });
<% end %>

If I’m correct in assuming your snippet comes from a Rails view.
