aurelia multi select

This is an Aurelia plugin in order for developers to create star-rate elements in their apps.

1. Installation

• Aurelia CLI

  run the following command :

  npm install aurelia-multi-select --save

  or if you are using yarn

  yarn add aurelia-multi-select

  then update the aurelia.json with the following :

  {
      "name": "aurelia-multi-select",
      "path": "../node_modules/aurelia-multi-select/dist/amd",
      "main": "aurelia-multi-select",
      "resources": [
        "elements/multi-select.html"
      ]
   }

  no need to mention that you should have added jquery and bootstrap in aurelia.json file

  "jquery",
    {
      "name": "bootstrap",
      "path": "../node_modules/bootstrap/dist",
      "main": "js/bootstrap.min",
      "deps": ["jquery"],
      "exports": "$",
      "resources": [
        "css/bootstrap.css"
      ]
    }

  then add the plugin in your main.ts or main.js file.

  .plugin("aurelia-multi-select")

• JSPM

  Run the jspm install command :

  jspm install aurelia-multiple-select=github:bondib/aurelia-multiple-select

  then update your main.ts or main.js file.

  .plugin("aurelia-multi-select")

2. Usage

Simple

Using the control in your .html files is so simple ;-)

<star-rate color="darkgoldenrod" read-only.bind="false" rate.bind="viewmodel.rate & validate" max-rate.bind="5"></star-rate>

keep in mind that once again you need the following line somwhere in your htmls :

<require from="bootstrap/css/bootstrap.css"></require>

Events

You can handle the callback for star rate clicked or changed in two forms :

1. Globally : When any of the star-rate elemnts in your dom which are not read only change the rate a StarRateClicked message will be published which has newRate and oldRate as its data

import { EventAggregator } from 'aurelia-event-aggregator';
import { StarRateClicked } from 'aurelia-multi-select';

and then subscribe fo the message :

@autoinject
export class Welcome {
  
  constructor(ea: EventAggregator) {
    ea.subscribe(StarRateClicked, x => console.info(`E.Aggregator : Rate changed from  ${x.oldRate} to ${x.newRate}`));
  }

}

2. Element based : You can handle seperate event callbacks for individual star-rate elements in your .html file use clicked.call as follows

 <star-rate clicked.call="star_clicked(newRate,oldRate)" max-rate.bind="8" rate.one-way="6" read-only.bind="false" color="darkgoldenrod"></star-rate>

and then in your .js or .ts file add your event handler :

private star_clicked(newRate, oldRate) {
    console.info(`clicked: Rate changed from  ${oldRate} to ${newRate}`);
}

3. Building The Code

To build the code, follow these steps.

1. Ensure that NodeJS is installed. This provides the platform on which the build tooling runs.
2. Ensure that Gulp is installed. If you need to install it, use the following command:

npm install -g gulp

3. From the project folder (root), execute the following command:

npm install && jspm install

4. Install the typings from the root

typings install

5. To build the plugin, you can now run:

gulp build

• You will find the compiled code in the dist folder, available in three module formats: AMD, CommonJS and ES2015.

6. to run the sample do the followings :

• run ```npm install && jsmp install`` in the sample older
• run gulp watch

7. See gulpfile.js for other tasks related to generating the docs and linting.
