Passing arbitrary arguments to handlebars helpers?
提问by Alexandros K
sorry if this has been asked a million times before but I can't seem to find a satisfactory answer anywhere.
对不起，如果这已经被问了一百万次，但我似乎无法在任何地方找到满意的答案。
I'm trying to build a handlebars helper to tie into my i18n library and I need it to accept any number of named arguments as follows:
我正在尝试构建一个把手助手来绑定到我的 i18n 库中，我需要它接受任意数量的命名参数，如下所示：
{{i18n yml.text.definition count=2 name="Alex" ... param="hello}}
which will translate to a call like this:
这将转化为这样的调用：
i18n.t("yml.text.definition", { count: 2, name: "Alex", ... param: "hello"})
Is this possible, or am I totally out of my tree?
这是可能的，还是我完全脱离了我的树？

Give the following helper:
提供以下帮手：
{{myHelper "foo" this ... key=value ...}}
You can get the data with the following declaration:
您可以使用以下声明获取数据：
Ember.Handlebars.helper('name', function(param1, param2, options) {
param1 // The string "foo"
param2 // some object in that context
options.hash // { key: value }
});
Each parameter of the function is the parameter passed in {{myHelper param1 param2}}. But the remaining will be an object with some special/private information. With that object you retrieve the key=value information using the hash object.
函数的每个参数都是在{{myHelper param1 param2}}中传入的参数。但剩下的将是一个带有一些特殊/私人信息的对象。通过该对象，您可以使用哈希对象检索 key=value 信息。
If the paramter supplied to the helper is quoted, like "param1", the string is returned, otherwise it's resolved to some object in that context.
如果提供给帮助程序的参数被引用，如“param1”，则返回字符串，否则将其解析为该上下文中的某个对象。
In your case you will need:
在您的情况下，您将需要：
Ember.Handlebars.helper('i18n', function(property, options) {
var hash = options.hash;
return 'i18n.t(' + property + ', { count: ' + hash.count + ', name: ' + hash.name + ', param: ' + hash.param + '})';
});

Try this:
试试这个：
Ember.Handlebars.registerBoundHelper('i18n', function(context, block) {
return i18n.t(context, { count: block.hash.count, name: block.hash.name, ... param: block.hash.param});
});
