How to use ng-repeat for dictionaries in AngularJs?

I know that we can easily use ng-repeat for json objects or arrays like:

<div ng-repeat="user in users"></div>

but how can we use the ng-repeat for dictionaries, for example:

var users = null;
users["182982"] = "{...json-object...}";
users["198784"] = "{...json-object...}";
users["119827"] = "{...json-object...}";

I want to use that with users dictionary:

<div ng-repeat="user in users"></div>

Is it possible?. If yes, how can I do it in AngularJs?

Example for my question: In C# we define dictionaries like:

Dictionary<key,value> dict = new Dictionary<key,value>();

//and then we can search for values, without knowing the keys
foreach(var val in dict.Values)
{
}

Is there a build-in function that returns the values from a dictionary like in c#?

You can use

<li ng-repeat="(name, age) in items">{{name}}: {{age}}</li>

See ngRepeat documentation. Example: http://jsfiddle.net/WRtqV/1/

I would also like to mention a new functionality of AngularJS ng-repeat, namely, special repeat start and end points. That functionality was added in order to repeat a series of HTML elements instead of just a single parent HTML element.

In order to use repeater start and end points you have to define them by using ng-repeat-start and ng-repeat-end directives respectively.

The ng-repeat-start directive works very similar to ng-repeat directive. The difference is that is will repeat all the HTML elements (including the tag it's defined on) up to the ending HTML tag where ng-repeat-end is placed (including the tag with ng-repeat-end).

Sample code (from a controller):

// ...
$scope.users = {};
$scope.users["182982"] = {name:"John", age: 30};
$scope.users["198784"] = {name:"Antonio", age: 32};
$scope.users["119827"] = {name:"Stephan", age: 18};
// ...

Sample HTML template:

<div ng-repeat-start="(id, user) in users">
    ==== User details ====
</div>
<div>
    <span>{{$index+1}}. </span>
    <strong>{{id}} </strong>
    <span class="name">{{user.name}} </span>
    <span class="age">({{user.age}})</span>
</div>

<div ng-if="!$first">
   <img src="/some_image.jpg" alt="some img" title="some img" />
</div>
<div ng-repeat-end>
    ======================
</div>

Output would look similar to the following (depending on HTML styling):

==== User details ====
1.  119827 Stephan (18)
======================
==== User details ====
2.  182982 John (30)
[sample image goes here]
======================
==== User details ====
3.  198784 Antonio (32)
[sample image goes here]
======================

As you can see, ng-repeat-start repeats all HTML elements (including the element with ng-repeat-start). All ng-repeat special properties (in this case $first and $index) also work as expected.

JavaScript developers tend to refer to the above data-structure as either an object or hash instead of a Dictionary.

Your syntax above is wrong as you are initializing the users object as null. I presume this is a typo, as the code should read:

// Initialize users as a new hash.
var users = {};
users["182982"] = "...";

To retrieve all the values from a hash, you need to iterate over it using a for loop:

function getValues (hash) {
	var values = [];
	for (var key in hash) {
		
		// Ensure that the `key` is actually a member of the hash and not
		// a member of the `prototype`.
		// see: http://javascript.crockford.com/code.html#for%20statement
		if (hash.hasOwnProperty(key)) {
			values.push(key);
		}
	}
	return values;
};

If you plan on doing a lot of work with data-structures in JavaScript then the underscore.js library is definitely worth a look. Underscore comes with a values method which will perform the above task for you:

var values = _.values(users);

I don't use Angular myself, but I'm pretty sure there will be a convenience method build in for iterating over a hash's values (ah, there we go, Artem Andreev provides the answer above :))

In Angular 7, the following simple example would work (assuming dictionary is in a variable called d):

my.component.ts:

keys: string[] = [];  // declaration of class member 'keys'
// component code ...

this.keys = Object.keys(d);

my.component.html: (will display list of key:value pairs)

<ul *ngFor="let key of keys">
    {{key}}: {{d[key]}}
</ul>
