通过Helper访问全局变量

Question

How can I access a global variable through a helper function in Handlebars.js for the purpose of localization? Here's what I've got so far. The problem I'm seeing is that the parameter 'string' is undefined inside the registerHelper anonymous function.

Template

<span>{{resourceHelper date}}:</span>

String Resources

Resources = {};
Resources['date'] = "Date";

Helper Function

Handlebars.registerHelper('resourceHelper', function(string) {
    return Resources[string];
});

Answer 1

I discovered that the parameter being passed into the helper was the actual object name within the Handlebars context. So passing date obviously didn't work, as there was no associated object in that context. You can, however, pass the values as strings:

{{resourceHelper "date"}}

This solved my problem with no other changes to the helper function required.
