Retrieve global variables using Helper

Seeking a way to utilize a global variable in Handlebars.js for localization purposes through a helper function. Currently encountering an issue where the 'string' parameter is undefined within the anonymous function of registerHelper.

Template

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

String Resources

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

Helper Function

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

Answer №1

After some investigation, I realized that the parameter being sent to the helper was actually the object name present in the Handlebars context. Hence, passing date didn't work as expected since there wasn't any corresponding object in that particular context. However, by passing the values as strings like this:

{{resourceHelper "date"}}

I managed to resolve my issue without having to make any other modifications to the helper function.
