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 the angular library yourself as it is now a peerDependency

1. Download package:
   • From npm npm install checklist-model
   • From bower bower install checklist-model
   • From latest release
2. Include script to the HTML:

   <script src='checklist-model.js'></script>
   

3. Add to app dependencies:

   var app = angular.module("app", ["checklist-model"]);
   

Usage

You should play with attributes of <input> tag:

• 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 doing checklistModelList = [] you should do checklistModelList.splice(0, checklistModelList.length) or wrap it in another object. Consequently, instead of doing checklistModelList = angular.copy(allValues) you should do checklistModelList.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 for checklist-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 from checklistModel, not with the one from ngModel. Afterwards the two will be kept in sync, but initially, these two can be conflicting, so only checklistModel is used. See the entire discussion at #104.

Development

How to run tests

1. Generate live demo index.html via grunt jade
2. Run local http server grunt server
3. Open in browser http://localhost:8000 to check that demo is accessible
4. Open in browser http://localhost:8000/test and wait until all tests pass

How to add a new test case

1. Create a new folder under docs/blocks named your-test.
2. Create under that folder ctrl.js to describe the test Angular controller, view.html to describe the view part in HTML and test.js for the Angular scenario test. You can use an existing test as an example.
3. Add a line like - items.push({id: 'your-test', text: 'Your test, ctrlName: 'CtrlTestName', testValue: 'selectedItems'}) to docs/index.jade
4. Add a line like <script src="../docs/blocks/your-test/test.js"></script> to test\index.html
5. Run grunt jade to generate index.html from docs/index.jade
6. Run grunt server
7. Access http://localhost:8000 for samples and http://localhost:8000/test for running the tests.

How to make a new release

1. Change the version number in package.json, bower.json and checklist-model.nuspec (if not already changed - check the version number against the latest release in Github)
2. 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.
3. Run npm publish to publish the new version to npm
