rater-js v1.0.1

Rater Js

rater-js is a star rating widget for the browser.

The author is looking for consulting work implementing anything with his open source libraries or other stuff. I do javascript/php/wordpress/c#/asp.net. I have over 10 years experience with software development. Keep in mind that I only work remotely.

Main features:

• Unlimited number of stars.
• Svg as background image makes it look good in any size.
• Custom css. Use your own image as star.
• RTL support.
• Touch support.

Installation

npm install rater-js --save

Usage

rater-js can be used with amd, commonjs or without any module loader using global scope.

In your html create an element that acts as the placeholder for the widget.

<div id="rater"></div>

Global scope

Directly reference the js from the module

<!--Add js before end body tag-->
<script src="node-modules/rater-js/index.js"></script>

The widget will be available globally as "raterJs" on the window object.

Node/Browserify

Just require the module.

var rater = require("rater-js");

Lastly we can use the widget like this:

 var myRater = rater({element: document.querySelector("#rater"), rateCallback: function rateCallback(rating, done) {
                //make async call to server however you want
                //in this example we have a 'service' that rate and returns the average rating
                myDataService.rate(rate).then(function(avgRating) {
                    //update the avarage rating with the one we get from the server
                    myRater.setRating(avgRating);
                     //we could disable the rater to prevent another rating
                     //if we dont want the user to be able to change their mind
                    myRater.disable();
                    //dont forget to call done
                    done();
                }, function(error) {
                        //handle the error
                        //dont forget to call done
                        done();
                });
	}});

Css will be injected at runtime, but you can override the css to get the look you want.

//change the whole image used as the star. Make sure to set starSize in options if not 16px.
//first image is for the 'off' mode
.star-rating {
        background: url("myStar_off.svg") !important;
}

//add style for 'on' mode
.star-rating .star-value{
        background: url("myStar_on.svg") !important;
}
