Question

I'm trying to learn how to use Snap and Heist and wanted to put links to JavaScript libraries in on place. I created this template in _js-libs.tpl:

<bind tag="jquery">
  <script type="text/javascript" src="/js/jquery-2.1.0.js"></script> 
</bind>
<bind tag="d3js">
  <script type="text/javascript" src="/js/d3.js"></script>
</bind>

And then tried this in the base.tpl template:

<html>
  <head>
    <title>Snap web server</title>
    <link rel="stylesheet" type="text/css" href="/screen.css"/>
     <apply template="_js-libs"/>
    <jquery/>
    <d3js/>
  </head>
  ... snip ...

But this just resulted in <jquery></jquery> and <d3js></d3js> in the page. I take it bind tags are not visible in a template which has applied the template containing the bind. How do I create top level tags like this in templates? I can only find examples of creating top level tags in Haskell code.

Was it helpful?

Solution

The bind tag only works locally to a template. The only exception to this is if you use bind tags inside the body of an apply tag as a mechanism to pass named "parameters" to the applied template.
