I have some data that I need to pass to JavaScript on a page. I'm using jinja2 to generate my page and here's how this is going:
In python:
some_json_data = json.dumps(some_data)
In jinja2:
JSON.parse('{% autoescape off %}{{ some_json_data }}{% endautoescape %}')
However, sometimes, some_json_data
could contain strings with \\n
as well as '
. Is there a library/some known function that I could use to escape these?
I know I could write this function with no problem, but I was wondering if there's already a library or something that does this. I've been looking around and haven't found anything.
Side note: My application is built on using Flask
You don't need to use JSON.parse
; the output is already valid JavaScript. You then don't need to put quotes around the JSON value either.
Generally, my JavaScript looks like:
<script language="javascript" type="text/javascript">
var serverJSValue = {% autoescape off %}{{ some_json_data }}{% endautoescape %};
</script>
