An unobtrusive JavaScript bundle for Symfony 2. Allows for using non-GET routes with simple links.

Dependencies

Symfony
jQuery

Installation

Install just like any other Symfony bundle. See the section below on security for further instructions.

After installing, you will need to run app/console assets:install or add @UjsBundle/Resources/public/js/ujs.js if you are using Assetic.

Usage

For any link that you would like to submit with an HTTP method other than GET, just include a data-method attribute, like so:

<a href="/posts/15" data-method="DELETE">Delete this post</a>

You may optionally include a data-confirm attribute, which will be used as the text in the JavaScript confirm dialog.

<a href="/posts/15" data-method="DELETE" data-confirm="Are you sure you
want to delete this post?">Delete this post</a>

If you set the data-confirm attribute to false, no confirmation message will be presented. Be careful with this, though, since browsers that do link prefetching may follow the link and perform destructive actions.

Security

Important!! If you do not implement these steps, your app will be vulnerable to cross-site scripting attacks!

First, you will need to include an HTML <meta> tag on any page that yo would like to use UJS. For example, add the following to your <head> section:

<meta name="_ujs_csrf_token" content="{{ csrf_token('ujs') }}" />
<meta name="_ujs_csrf_token_name" content="_ujs_csrf_token" />

Any controller action that you would like to submit with UJS should check the CSRF token to make sure it is valid, like so:

public function deleteAction(Request $request)
{
    if ($request->request->has('_ujs_csrf_token') && $this->get('form.csrf_provider')->isCsrfTokenValid('ujs', $request->request->get('_ujs_csrf_token'))) {
        // Do your deleting, posting, etc.
    }
}
