玉在迭代中获取对象键名

Question

var data = {
  thing: 'value1',
  thing2: 'value2',
  thing3: 'value3'
};

each val, index in data
    li= val.keyname??

The output I want is:

<li>thing</li>
<li>thing2</li>
<li>thing3</li>

Is this possible?

I tried just using 'index', but it iterated on the entire list of properties and prototype functions attached to the object, eg $__, isNew, errors, _doc, $__original_save, save, _pres, _posts, toObject, toJSON, $__isNested etc..

The data is from part of a find query from MongoDB.

In my usecase I do not know the names of the keys beforehand.

Answer 1

Data must be a simple key-value object.

If You have most complicated object (like model or collection) use a toJSON pattern like in Backbone.Model or Backbone.Collection .

If You have a simple object, use each val, idx like this:

ul
  each val, idx in data
    li= idx

Use library UnderscoreJS's invert method. Underscorejs.org
