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 :
我不明白你选择的解决方案到底是什么问题，它应该适用于 {{ app.user }} ，除了 app.user 是一个对象，所以你应该有一个 toArray 函数进入你的用户并调用：
app_user = {{ app.user.toArray|json_encode() }};
Or call each parameter of the user like {{ app.user.id }}
或者像 {{ app.user.id }} 这样调用用户的每个参数
Documentation : https://twig.sensiolabs.org/doc/filters/json_encode.html
文档：https: //twig.sensiolabs.org/doc/filters/json_encode.html
You should use json_encode for your variables above, if you have a quote into one of your string it will break your javascript.
您应该对上面的变量使用 json_encode，如果您在其中一个字符串中有引号，它会破坏您的 javascript。
Example for profile:
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>

The accepted solution doesn't work (anymore ?) because of twig autoescaping the outputs, changing all the JSON "with ".
接受的解决方案不起作用（不再起作用？），因为树枝自动转义输出，"用"更改所有 JSON 。
Equivalent would now have to use the rawfilter:
等效项现在必须使用raw过滤器：
<script type="text/javascript">
nickname = {{ profile.nickname|json_encode()|raw }}; // Nickname will be a string
// 2nd solution if you have more informations related to profile
profile = {
nickname: {{ profile.nickname|json_encode()|raw }},
lastname: {{ profile.lastname|json_encode()|raw }}
};
// Profile is now an object with a nickname property.
// use profile.nickname on your javascripts
</script>
That being said, directly printing the raw JSON into the javascript may cause some problems, has in this configuration:
话虽如此，直接将原始 JSON 打印到 javascript 中可能会导致一些问题，在此配置中有：
<script>
var myvar = {{ '{"test": "</script>"}'|raw }};
</script>
The </script>tag in the JSON would be interpreted by the HTML parser, resulting in a broken script.
</script>JSON 中的标记将由 HTML 解析器解释，从而导致脚本损坏。
The truly correct way to do this would rather be to print the JSON as an escaped string, and then parse it within the js script:
真正正确的方法是将 JSON 打印为转义字符串，然后在 js 脚本中解析它：
<script>
var myvar = JSON.parse('{{ '{"test": "</script>"}'|e('js') }}');
</script>

Try this:
试试这个：
var title = '{{ 'My Daily Activities'|trans({}, 'general') }}';
with additional apostrophy
附加撇号

Use an attribute or any tag
使用属性或任何标签
example: <span profile="{{ profile.nickname }}"></span>
例子： <span profile="{{ profile.nickname }}"></span>
