Angularjs Ng Repeat Key Value Array

Or better use an array containing objects with a key attribute and a value attribute.

Angularjs ng repeat key value array. Isabelhm for many reasons a lot of us recommend against iterating over objects in an ngrepeat in fact i once heard a core team member regret ever implementing the ability to do so. Previously the order of items when using ngrepeat to iterate over object properties was guaranteed to be consistent by sorting the keys into alphabetic order. The example below makes use of this feature. The collection must be an array or an object.

Here the variable key contains the key of the object and value contains the value of the object. The set of html will be repeated once per item in a collection. Each instance of the repetition is given its own scope which consist of the current item. Ng repeat is a built in directive in angular which lets you iterate an array or an object and gives you the ability to repeat an element once for each item in the collection.

The task is to iterate over a js object its keys and values using the ng repeat directive. This is fixed as of angular 1 4. The ng repeat directive repeats a set of html a given number of times. The ng repeat start directive works the same as ng repeat but will repeat all the html code including the tag it s defined on up to and including the ending html tag where ng repeat end is placed.

Fyi a template in angularjs is referred to the html with angular specific elements and attributes directives etc. Join the community of millions of developers who build compelling user interfaces with angular.

As the directive name suggests the ng repeat instantiates a set of html or template for each item in the given collection. Make sure the array is on the scope. Use an object rather than an array.
