Handlebars : What is the best way to pass multiple parameters to a registerHelper function?

I am using Handlebars to render data in a table.

One of the data items needs processing, which takes a few parameters into account in order to provide outcome.

The templated text example : 

{{getOutputByParameters param1=DataFieldName1 param2=DataFieldName2}}

And corresponding registerHelper would be written as:

var __this = this;
Handlebars.registerHelper('getOutputByParameters', function(params){ __this.getOutputByParameters(params.hash.param1, params.hash.param2)})

I figured that handlebars would pass an array of these parameters, which I can access using hash property.

But is that the only best way?

Solution

  • Nope. As per their document you can do this in many ways. I would do this way.

    {{getOutputByParameters param1 param2}}

Handlebars.registerHelper('getOutputByParameters', function(param1, param2){ 
//do your stuff here.
})
