Question

I would like to run JSHint on all my Javascript source files but several of them have some embedded Django template markup. JSHint throws a ton of errors on this markup.

Is there a way to either…

1. Tell JSHint to ignore this markup
2. Run the Djnago template parser with some dummy data to generate all permutations of the rendered js file and then run JSHint on that?

I assume I could write a bunch of code to do #2 but i’m wondering if there’s an easier way.

Answer 1

Depending on a markup you can get away with “hiding” Django markup with JavaScript comments. We do this, for example:

// {% if cond %}
someJavaScriptCode();
// {% else %}
somethingElse();
// {% endif %}

// {% include "script.js" %}

The only thing is that you have start script.js with a blank line—otherwise // will eat the first legitimate line of JavaScript code you have there. I wrote a simple helper {% includejs %} that does that for me automatically.
