EmberJs：在Handlebars-helper中呈现模板 [英] EmberJs: render template inside Handlebars-helper

问题描述

我有这种情况，我将模板名称存储在一个变量中。我注意到，如果你有例如

I have this situation in which I have the template-name stored in a variable. I noticed that if you have for example

var config = { view: "PeopleView", .... } ;

你不能这样做

{{view App[config.view]}}

这是可能的，我仍然对解决方案感兴趣！
无论如何，我决定用Handlebars helper来解决这个问题：

If this is possible, I'm still interested in the solution! Anyway, I decided to fix this with a Handlebars helper:

{{setVariableView config}}

...

Ember.Handlebars.registerBoundHelper('setVariableView', function(value, options) {
    return App[value.view].create(value) ; // <-- this doesn't work :)
}) ;

此时我不知道如何调用编译的PeopleView？
有什么建议吗？

At this point I don't know how to call the compiled PeopleView ? Any suggestions ?

干杯

Cheers

推荐答案

我们希望创建你的配置对象，就像你做的那样：

First you'll want to create your configuration object, as you've done:

App.config = Ember.Object.create({ view: 'App.MyView' });

然后你想注册你已经完成的助手，但需要修改它一点点，因为视图需要手动 append ed当你采取这种方法时：

And then you want to register your helper, which you've done, but it needs to be modified a little bit, since views need to be manually appended when you take this approach:

Ember.Handlebars.registerBoundHelper('setVariableView', function(value, options) {
    var view = eval(value.view).create();
    view.append();
});

现在您可以将配置文件传递给 setVariableView helper，它会呈现传递给你配置的视图：

And now you can pass in the configuration file to your setVariableView helper, and it will render the view that was passed in to your configuration:

{{setVariableView App.config}}

唯一值得关注的是 eval 。也许这是清晨没有帮助，但我现在想不出更好的选择。

The only concern is the utilisation of eval. Maybe it's the early morning that's not helping, but I can't think of a better alternative at the moment.
