Pass JavaScript object/hash to Handlebars helper?

Question

Is it possible to pass a JavaScript object/hash into a Handlebars helper call? I\'d like to do something like this:

Label here
{{#

Solved. I did this:

Helper:

Handlebars.registerHelper('textField', function(options) {
    var attributes = [];

    for (var attributeName in options.hash) {
      attributes.push(attributeName + '="' + options.hash[attributeName] + '"');
    }

    return new Handlebars.SafeString('');
});

And the template:

Label here
{{textField id="text_field_1" class="some-class" size="30" data-something="data value"}}

Per the documentation (bottom of the page), you can pass in a variable number of parameters to a helper method, and they will be available in options.hash (assuming "options" is a parameter to your helper method). And what's also nice about this is that you can use named parameters, and parameter order doesn't matter.
