Yes; you generally put context-specific information like expanded routes into the templates and access this information from your (static) JavaScript libraries.

Including the context info can be done in various ways, depending on taste:
1. You could use a data attribute on a tag in your generated HTML:
```
<body data-viewurl="http://www.example.com/route/to/view">
    ...
</body>
```
  which you then, in your static JS code load with the jQuery .data() function:
```
var viewurl = $('body').data('viewurl');
```
2. Use a made-up LINK tag relationship to include links in the document head:
```
<head>
    <link rel="ajax-datasource" id="viewurl"
          href="http://www.example.com/route/to/view" />
    ...
</head>
```
  which can be retrieved using $('link#viewurl').attr('href'), or $('link[rel=ajax-datasource]').attr('href'). This only really works for URL information.
3. Generate JS variables straight in your template, to be referenced from your static code:
```
<head>
    ...
    <script type="text/javascript">
       window.contextVariables = {
           viewurl = "http://www.example.com/route/to/view",
           ...
       };
    </script>
</head>
```
  and these variables are referable directly with contextVariables.viewurl.
