I have this controller.php

    $repository = $this->getDoctrine()->getManager()->getRepository('TechappStatsBundle:ParentForm');
    $data = $repository->findBy(array(),array('id' => 'desc'),1,0); 

    $formulaire = new ParentForm();

    $parent= $this->get('form.factory')->create(new ParentFormType(),$formulaire);

    if ($parent->handleRequest($request)->isValid()) {
        $em = $this->getDoctrine()->getManager();

    return $this->render('TechappStatsBundle:Stats:index.html.twig',array("res" => $data,

I want to check the variable res in my view with js if it is equals to a specific value or not but I don't know how to pass it.

  $ repository = $ this-> getDoctrine() - > getManager() - > getRepository('TechappStatsBundle:ParentForm'); 
 $ data = $ repository-> findBy(array()  ,array('id'=>'desc'),1,0);  
 $ formulaire = new ParentForm(); 
 $ parent = $ this-> get('form.factory') - > create(new ParentFormType(),$ formulaire); 
  if($ parent-> handleRequest($ request) - > isValid()){
 $ em = $ this-> getDoctrine() - > getManager(); 
 $ em-> persist($ 公式); 
 $ em-> flush(); 
返回$ this-> render('TechappStatsBundle:Stats:index.html.twig',array(“res”=> $ 数据,
“parentform”=> $ parent-> createView(),)); 

我想检查变量 res < / code>在我的视图中使用js,如果它等于某个特定值,但我不知道如何传递它。

    You can pass the parameters from controller like:

    return $this->render('TechappStatsBundle:Stats:index.html.twig', array(
                    "res" => "Your data here"));

    And you can access the "res" parameter in index.html.twig like:

    {% block js %}
     <script type="text/javascript">
    var res = '{{ res }}';
    {% endblock %}

    If you want to pass data to Javascript, you can update your view to either:

    • Add an hidden input (if this is a form) that contains the value of the data
    • Add data to a DIV or P (or whatever) that you hide with CSS
    • Add an attribute to a specific field, for example data-<field>

    Once you get it, you can easily fetch the value from jQuery.

    My option always is send it in a data-value,

    You can do something like

    <div id="res-result" data-res="{{ res }}" style="display: none;">

    The div doesn't need to be hidden, if it's something related with a div I always put it inside the div related, even if it's not hidden

    And then from Jquery:

    resValue = $('#res-result').data('res');

    Having the JS file outside of the HTML is the cleanest way IMO
