Javascript中的变量Twig [英] variable Twig in Javascript

问题描述

我怎样才能将{{app.user}}传递给Javascript？

How can i pass {{app.user}} into Javascript ?

现在我做了一个像这样的块;

for now I do a block like;

<script type="text/javascript">
    var app_name = '{{ app_name }}';
    var app_url= '{{ app_url }}';
    var app_description= '{{ app_description }}';
    var app_email= '{{ app_email }}';
    var app_title= '{{ app_title }}';
    var app_dominio= '{{ app_dominio }}';
    var env = '{{ app.environment }}';
</script>

这些参数在config.yml中设置

where these parameters are set in config.yml

推荐答案

我不明白您选择的解决方案究竟是什么问题，它应该与{{app.user}}一起使用，除了app.user是一个对象，所以你应该在你的用户中使用toArray函数并调用：

I don't understand what's exactly your problem with the solution you choose, it should work well with {{ app.user }} except that app.user is an object, so you should have a toArray function into your user and call :

app_user = {{ app.user.toArray|json_encode() }};

或调用用户的每个参数，如{{app.user.id}}

Or call each parameter of the user like {{ app.user.id }}

文档： https://twig.sensiolabs.org/doc/filters/json_encode.html

你应该使用json_encode为你的上面的变量，如果你的一个字符串中有引号，它将破坏你的javascript。

You should use json_encode for your variables above, if you have a quote into one of your string it will break your javascript.

个人资料示例：

<script type="text/javascript">
    nickname = {{ profile.nickname|json_encode() }}; // Nickname will be a string
    // 2nd solution if you have more informations related to profile
    profile = {
        nickname: {{ profile.nickname|json_encode() }},
        lastname: {{ profile.lastname|json_encode() }}
    };
    // Profile is now an object with a nickname property.
    // use profile.nickname on your javascripts
</script>
