How to execute a JavaScript function when returning HttpResponse?

Question

Here's my scenario: User adds something to the shopping cart, and if the python view handling this logic does it successfully, it should fire off a JavaScript function saying 'You've added a product into your cart!'.

How would one go about doing that?

Here's what I tried so far:

return HttpResponse("alert('hello world');", mimetype="application/x-javascript")

but this just outputs the code as a string.

To be specific: I need to fire a function in a JS file.

In django 1.9 the following code works:

return HttpResponse("<script>alert('hello world');</script>")

This works, but I need to fire a specific function in a JS file. Any tips?

If your javascript file is included in the response you can just call the function in the script tags above. If i were you I would first write a html site that works, then copy the html and return it in the HttpResponse

If I add src tag, like this: pastebin.com/uKduU9L3, it suddenly stops working.

it seems you need some training in javascript. try it on an empty html page before trying it in django. tip: you need two script tags.
