checklist-model
AngularJS directive for list of checkboxes
Why this is needed?
In Angular one checkbox <input type="checkbox" ng-model="...">
is linked
with one model.
But in practice we usually want one model to store array of checked values
from several checkboxes.
Checklist-model solves that task without additional code in controller.

Installation
Note: since version
1.0.0
you must install theangular
library yourself as it is now apeerDependency
- Download package:
- From npm
npm install checklist-model
- From bower
bower install checklist-model
- From latest release
- From npm
- Include script to the HTML:
<script src='checklist-model.js'></script>
- Add to app dependencies:
var app = angular.module("app", ["checklist-model"]);
Usage
You should play with attributes of <input>
tag:
Attribute | Mandatory | Description |
---|---|---|
checklist-model |
Yes | Use instead of ng-model |
checklist-value |
No | What should be picked as array item |
value |
No | What should be picked as item, but unlike checklist-value , this does not evaluate as an angular expression, but rather a static value |
ng-model |
No | Every checkbok will span a new scope and define a variable named checked to hold its state. You can modify this name by using this attribute. |
checklist-comparator |
No | A custom comparator. If it starts with dot(. ) then it will be an expression applied to the array item. Otherwise it should evaluate to a function as an angular expression. The function return true if the first two arguments are equal and false otherwise. |
checklist-before-change |
No | An angular expression evaluated each time before the checklist-model has changed. If it evaluates to 'false' then the model will not change anymore. |
checklist-change |
No | An angular expression evaluated each time the checklist-model has changed. |
- If you modify directly the value of the
checklist-model
, it is possible that the UI won't be updated. This is because this directive looks for the model in the parent, not in the current scope. Instead of doingchecklistModelList = []
you should dochecklistModelList.splice(0, checklistModelList.length)
or wrap it in another object. Consequently, instead of doingchecklistModelList = angular.copy(allValues)
you should dochecklistModelList.push.apply(checklistModelList, allValues)
. The idea is to use the same array and not replace it with a new one. - If you're using
track by
you must specify the same thing forchecklist-value
too. See #46. - If you're also using
ngModel
, please keep in mind that the state of the checkbok is initialized with the value fromchecklistModel
, not with the one fromngModel
. Afterwards the two will be kept in sync, but initially, these two can be conflicting, so onlychecklistModel
is used. See the entire discussion at #104.

Development
How to run tests
- Generate live demo index.html via
grunt jade
- Run local http server
grunt server
- Open in browser http://localhost:8000 to check that demo is accessible
- Open in browser http://localhost:8000/test and wait until all tests pass
How to add a new test case
- Create a new folder under
docs/blocks
namedyour-test
. - Create under that folder
ctrl.js
to describe the test Angular controller,view.html
to describe the view part in HTML andtest.js
for the Angular scenario test. You can use an existing test as an example. - Add a line like
- items.push({id: 'your-test', text: 'Your test, ctrlName: 'CtrlTestName', testValue: 'selectedItems'})
todocs/index.jade
- Add a line like
<script src="../docs/blocks/your-test/test.js"></script>
totest\index.html
- Run
grunt jade
to generateindex.html
fromdocs/index.jade
- Run
grunt server
- Access
http://localhost:8000
for samples andhttp://localhost:8000/test
for running the tests.
How to make a new release
- Change the version number in
package.json
,bower.json
andchecklist-model.nuspec
(if not already changed - check the version number against the latest release in Github) - Create a new release in github with the same name for tag and title as the version number (e.g.
1.0.0
). Do not forget to include the changelog in the release description. - Run
npm publish
