can-key/walk/walk

  • Edit on GitHub

walk(obj, name, keyCallback(info) )

import walk from "can-key/walk/walk";

var user = {name: {first: "Justin"}}
walk(user, "name.first", (keyInfo)=> {
  // Called 2 times.
  // first call:
  keyInfo //-> {parent: user, key: "name", value: user.name}
  // second call:
  keyInfo //-> {parent: user.name, key: "first", value: user.name.first}
})

Parameters

  1. obj {Object}:

    An object to read key values from.

  2. name {String}:

    A string key name like "foo.bar".

  3. keyCallback {function(info)}:

    For every key value, keyCallback will be called back with an info object containing:

    • info.parent - The object the property value is being read from.
    • info.key - The key being read.
    • info.value - The key's value.

    If keyCallback returns a value other than undefined, the next key value will be read from that value.
