Access to property of other object in parent level

[uoziod]

I have 2 objects coming to template:

foo: {
  some: {
    use: "item1"
  },
  thing: {
    use: "item3"
  }
},
bar: {
  item1: {...},
  item2: {...},
  item3: {...}
}

Using {{#each}} helper I switching every foo's property. Inside of each we have use property contains text value of property in bar object that I want to use.

How can I get access to them?

{{doSomething ../bar.[this.use]}}

Doesn't work.

@uoziod In this case, I would pass the bar object and the this.use to the doSomething helper, and update the doSomething helper to get the correct item:

handlebars.registerHelper('doSomething', function(items, itemname) {
  var item = items[itemname];
  ...
  return 'something done';
});

{{doSomething ../bar this.user}}

Hope this helps.

In this case I have another question: how to access to results of helper1 inside of helper2?)

[doowb]

You can call helper1 from within helper2...

Handlebars.registerHelper('helper2', function(input) {
    // pass input to helper1 to do something
    var output = Handlebars.helpers.helper1.call(this, input);
    // do something else
    var finaloutput = output;
    return finaloutput;
});

There isn't a way to chain helpers within the markup/template syntax though.

@doowb, great! Thank you!

Closing as I think this is answered (thanks @doowb) and #569 tracks the in-language support for something like this, whatever that might look like.

Please let me know if there are still issues.
