As you can guess this is general problem for all backend languages for passing data to JS.

-- AFAIK the standard practice is attaching the value to a DOM element as "data" property and using fetching the value from that element in your JS. If it is a primitive value it is easy to do so, if it is relatively complex structure, e.g. dictionary of classes etc. you can create a string representation of it (maybe in JSON format) and pass it to the template. Check out this link's method #4, it is on .NET but the idea is the same: https://blog.mariusschulz.com/2014/02/05/passing-net-server-side-data-to-javascript.
Hope it helps!

I am trying to pass values from Django/Python to Javascript, and have it working to a degree, but need some assistance (obligatory: I'm new to Django so could be hosing this)I have three files in play here, views.py, app.js, home.html. I can get the values passed to home.html as part of the render, but I can't get the code to work outside of the home.html file. Below is a very simplified example of what I'm doing.VIEWS.PYreturn render(request, "home.html", {'data':data'})HOME.HTML<html>
<head>
<script src="{% static '/js/app.js' %}"></script>
<script>
myFunction({{ data | safe }});
</script>
</head>
</html>
APP.JS
function myFunction(vars){return vars};I would like to have the JS in the HTML file in the APP.JS file so I can centralize all Javascript, but cannot get it to work outside the HTML. I also tried sending the "data" to JSON using "json.dumps" but got an error that the data was not serializable, so went with this code posted above.Can I do what I'm trying to do?ThanksSteve
