I want to external my js code but there is twig variable. What are your tricks ?
team: {{ 'Select your team'|trans }}
Thanks,
I just set my twig vars as globals before requiring any javascript files.
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script>
var my_twig_var = {% if twig_var is defined %}'{{ twig_var }}'{% else %}null{% endif %}
</script>
<script src="scripts/functions.js"></script>
</body>
</html>
Another aproach I use is to forsee a javascript block in my main template
base.twig.html
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
{% block body %}
{% endblock %}
{% block javascript %}
{% endblock %}
</body>
</html>
page.html.twig
{% extends base.twig.html %}
{% block body%}
<h1>Hello World</h1>
{% endblock %}
{% block javascript %}
<script>
alert('{{ twig_var|default('Hello World') }}');
</script>
{% endblock %}
