How to Generate Routing URLs in JavaScript

Warning: You are browsing the documentation for Symfony 2.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.2 (the current stable version).

If you're in a Twig template, you can use the same path() function to set JavaScript variables. The escape() function helps escape any non-JavaScript-safe values:

1
2
3
<script>
var route = "{{ path('blog_show', {'slug': 'my-blog-post'})|escape('js') }}";
</script>

2.8

The path() PHP templating helper was introduced in Symfony 2.8. Prior to 2.8, you had to use the generate() helper method.

But if you actually need to generate routes in pure JavaScript, consider using the FOSJsRoutingBundle. It makes the following possible:

1
2
3
4
5
<script>
var url = Routing.generate('blog_show', {
    'slug': 'my-blog-post'
});
</script>
