How do i pass jinja2 data into javascript.
I have a Flask REST url as /logs/<test_case_name>
I am trying use .getJSON() to query the above URL and hence would want to pass the jinja2 data which has the testcasename to .getJSON function.

sample code:

<script type=text/javascript>

  alert({{name}});

</script>

It doesn't work.
Any suggestions please?

other than encapsulating the variable in a string, an alternate is jquery for profit:

its generally a bad idea to mix template language with javascript. An alternative would be to use html as a proxy - store the name in an element like so

<meta id=my-data data-name={{name}} data-other={{other}}>

then in the javascript do

var djangoData = $('#my-data').data();

this has advantage in:

javascript no longer tied to the .html page

jquery coerces data implicitly
