javascript 把手：将多个参数传递给 registerHelper 函数的最佳方法是什么？

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

提问by dhruvpatel

I am using Handlebars to render data in a table.

我正在使用 Handlebars 在表格中呈现数据。

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

其中一个数据项需要处理，需要考虑几个参数才能提供结果。

The templated text example :

模板化文本示例：

{{getOutputByParameters param1=DataFieldName1 param2=DataFieldName2}}

And corresponding registerHelper would be written as:

相应的 registerHelper 将写为：

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.

我认为车把会传递这些参数的数组，我可以使用 hash 属性访问这些参数。

But is that the only best way?

但这是唯一最好的方法吗？

Nope. As per their documentyou can do this in many ways. I would do this way.

不。根据他们的文档，您可以通过多种方式执行此操作。我会这样做。

{{getOutputByParameters param1 param2}}

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