Going from Pandas Dataframe to Javascript Array

Question

I need to create an array in an HTML file of the form:

<script>
   var markers = [
         [1, 2],
         [3, 4]
         ];
</script>

I can get this array from either one of two sources: python via pandas or sql. I know how to get the list into a flat file or json, but do not know how to get that list into the javascript array.

What's a good way to do this?

plz post your list, as an assumption you can result = json.dumps(list) from python end and JSON.parse(result) from javascript end. — A l w a y s S u n n y

I don't follow. if you can save the data to a flat file, what's the problem? Also, is this running via HTTP or locally? — Ben Harold

Sorry, that is the problem. I can dump a flat file to a local server but then I don't know how to get the contents into the javascript array. Running locally. — racket99

json is something like this: {"a":{"0":-64.08,"1":-64.09},"b":{"0":42.13,"1":42.12}} — racket99

In Django example, you do this:

view.py

data = df.to_dict(orient='records')
return render(request, 'XXX.html',{'data':data})`

in template:

data = {{ data|safe }};
