Description

add is a function similar to JavaScript's Array#push method, in that it appends a new element to an array. The difference is that the value being added is optional and defaults to an empty object.

Note: this function is used to augment the Array type in angular expressions. See angular.Array for more info.

Usage

angular.Array.add(array[, value]);

Parameters

array – {Array} –
The array expand.
value(optional={}) – {*} –
The value to be added.

Returns

{Array} –

The expanded array.

Example

This example shows how an initially empty array can be filled with objects created from user input via the $add method.

[<a href="" ng:click="people.$add()">add empty</a>] [<a href="" ng:click="people.$add({name:'John', sex:'male'})">add 'John'</a>] [<a href="" ng:click="people.$add({name:'Mary', sex:'female'})">add 'Mary'</a>] <ul ng:init="people=[]"> <li ng:repeat="person in people"> <input name="person.name"> <select name="person.sex"> <option value="">--chose one--</option> <option>male</option> <option>female</option> </select> [<a href="" ng:click="people.$remove(person)">X</a>] </li> </ul> <pre>people = {{people}}</pre> beforeEach(function() { expect(binding('people')).toBe('people = []'); }); it('should create an empty record when "add empty" is clicked', function() { element('.doc-example a:contains("add empty")').click(); expect(binding('people')).toBe('people = [{\n "name":"",\n "sex":null}]'); }); it('should create a "John" record when "add \'John\'" is clicked', function() { element('.doc-example a:contains("add \'John\'")').click(); expect(binding('people')).toBe('people = [{\n "name":"John",\n "sex":"male"}]'); }); it('should create a "Mary" record when "add \'Mary\'" is clicked', function() { element('.doc-example a:contains("add \'Mary\'")').click(); expect(binding('people')).toBe('people = [{\n "name":"Mary",\n "sex":"female"}]'); }); it('should delete a record when "X" is clicked', function() { element('.doc-example a:contains("add empty")').click(); element('.doc-example li a:contains("X"):first').click(); expect(binding('people')).toBe('people = []'); });
