How To Read Python List In Javascript [in A Django Template]

Solution 1:

It sounds like your data is already JSON, otherwise you would be getting single quotes and u prefixes. So the only issue is Django autoescaping; you can disable it with the safe filter:

var filtered_elements = {{ array|safe }};

Solution 2:

Your data should be JSON, instead of putting the Python list into the contact directly, put "array": json.dumps(array) in the context dictionary.

The JSON string doesn't need HTML escaping inside a tag, but it does need JS escaping! Otherwise some string may include something like </script><script>absolutely anything goes here... to run arbitrary JavaScript, if the JSON contains user data.

So use |escapejs:

var filtered_elements = {{ array|escapejs}};
