Menu
In the server I render a template with an argument, like this:
self.render('templates/test.html', names="['Jane', 'Tom']")
And I successfully got it in the <script> of test.html by this:
var N = "{{ names }}";
Now I want to seperate the js code and html :
<script type="text/javascript" src="static/test.js"></script>
but it failed when I put the N = "{{ names }}" in that js file.
Can anyone tell me what to do with that ? Thanks !

You can create setter function to be called from HTML file to have argument passed:
$ tree
.
├── static
│ └── scripts
│ └── test.js
├── templates
│ └── index.html
└── test.py

var test = ""
function set_test(val)

test=val
