呈现Play！Framework2 JavaScript作为模板? [英] Render a Play!Framework2 javascript as template?

问题描述

我想从Play！Framework 2中的模板返回一个.js文件.

I'd like to return a .js file from a template in Play!Framework 2.

这就是我的做法:

在我的views文件夹中，创建了一个模板文件:

In my views folder, I created a template file :

initials.scala.js

包含类似以下内容的

Containinig something like :

{
    'data': @Model.find.findList()
}

然后，在我的控制器中:

And then, in my controller :

public static Result initials() {
    return ok(views.js.initials.render());
}

这对我来说很简单，但是我得到了这个错误:

This is pretty straighforward for me, but I get this error :

错误:软件包views.js不存在

error: package views.js does not exist

我做错了什么?

如果我将js重命名为txt(在文件名和控制器中的包调用中)，则一切正常.但是，如果我将其更改为js，则会收到错误消息.

If I rename js to txt (in the filename and the package call in the controller), everything works fine. But if I change it to js, I get an error.

推荐答案

您没做错什么，Play允许您仅将.html，.xml或.txt扩展名用于视图，因此您需要使用以下一种他们.

You did nothing wrong, Play allows you tu use only .html, .xml or .txt extensions for views, so you need to use one of them.

从技术角度来看，使用哪一个都没有关系，无论如何，您都需要将其作为JavaScript从控制器中返回，即:

From technical point of view it doesn't matter which one you'll use, anyway you need to return it from controller as JavaScript, ie with:

public static Result initials() {
    return ok(views.html.initials.render()).as("application/javascript");
}
