How to use Django variable in JavaScript file

0 votes

I know that we can use Django variable in templates(html files) with {{variable}}, but how can I use a variable Django in a Javascript file that included in the template?

For example here is my template.html:

<html>
<head>
<script src="/static/youtube.js"></script>
...

how can I use variable {{user.get_username}} in youtube.js? not in template.html cause I did't wrote my script here...and when I use {{user.get_username}} in Javascript file youtube.js it caused an error "invalid token { ", but in the template it works fine.

Hello @kartik,

You need to print it before your script tag

<html>
<head>
<script>
    var username = {{user.get_username}};
</script>
<script src="/static/youtube.js"></script>
...

Then you can use the username variable inside your youtube.js as it is declared as a javascript global variable.

Hope it helps!!
