How to use ng-repeat for dictionaries in AngularJs?

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 :))
