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.

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-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 doing checklistModelList = [] it is better to do checklistModelList.splice(0, checklistModelList.length) or wrap it in another object.
• If you're using track by you must specify the same thing for checklist-value too. See #46.

• Fill in an issue.

Please keep in mind to also create a Plunkr or JSFiddle example. This will greatly help us in assisting you and you can use one of the existing examples and fork it.

Development

We're using grunt as the build system. grunt jade generates the demo file and grunt server starts the demo server that can be access at http://localhost:8000. Tests can be ran by accessing http://localhost:8000/test.

The best way to involve is to report an issue/enhancement and then provide a pull request for it using Github usual features.

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 bower.json and package.json
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
