How to translate using flask-babel on javascript?

Question

I have a python project with jinja templates and flask-babel working good. My problem are javascript files. I have all the js files inside a folder called 'static', but after using:

var food = gettext('food');

Then updating and compiling, the browser returns an error :

gettext is not defined

I've seen some projects using babel.js or jsil18n but I'm not sure if I really need that. How can I define gettext the same same way I did with my jinja templates?

Answer 1

如果 food 是一个字符串，那么您可以使用以下语法，前提是您的 messages.po 文件中有 food 的翻译：

var food = "{{_('food')}}";
