yes brother you can it is very easy
just put your condition in and if
you should have to know how the if condition is working in django templates


{% ifequals comparator1 comparator2 %}

call javascript function from here

{% end ifequals %}

A slight variation of this approach is to map some Django template context info to Javascript variables in one of your templates, making that data accessible to your compressed / minified JS code:

# in a template, "base.html" perhaps..

<script>

window.DjangoContext = {

  userLoggedIn: {{ user.is_authenticated|yesno:"true,false" }}

}

</script>

Note the use of the 'yesno' filter to convert "True" to "true" to match JS syntax.

Now you can access DjangoContext.userLoggedIn anywhere in your JS.

** It's important to note that users can modify any JS variable they wish, so don't rely on something like this for security **
