Handlebars.js：是否可以将多个散列作为参数传递给Handlebars助手？

Question

Let's say I have declared following helper

Handlebars.registerHelper("linkTo", function(request, params) {
    return window.linkTo(request, params);
});

how can I (if possible) do something like this in the view (not correct syntax, just for show purposes)

<a href="{{link_to module='products' controller='view', product=product.id artist= artist.id}}">foo</a>

the comma just symbolises separation between the two hashes.

Answer 1

否 ，由于Handlebars.js使用参数的方式，因此无法分隔多个哈希。

Answer 2

If you can see your way to putting your parameters into a structure that you can pass as part of an object literal then I know that will work. For example:

{ 
  "params" : {
    "module" : "products",
    "controller" : "view",
    "product" : 5,
    "artist" : 25
  }
}

Plus this helper:

Handlebars.registerHelper("link_to", function(params) {
  var result = "";
  var insertAmpersand = false;

  for (var prop in params) {
      if (insertAmpersand) {
          result += "&";
      } else {
          insertAmpersand = true;
      }

      result += prop + "=" + params[prop];
  }
  return result;
});

Can be called like so:

{{link_to params}}

To generate:

module=products&controller=view&product=5&artist=25

Obviously you would want to refine that so that things had the right quote marks around it, etc. But would something like that work for you?
