Tiny Star Rating System In Vanilla JavaScript

A lightweight, Vanilla JavaScript-only star rating system for ranking products, services, or articles on your web page.

Features:

• Fractional rating support.
• Custom min/max/intial rating values.
• Readonly mode.
• Custom rating symbols. Not only stars.

How to use it:

1. Load the main JavaScript in the document and we’re ready to go.

<script src="./index.js"></script>

2. Create a container in which you want to insert the rating system.

<div class="starRatingContainer">
  <div class="className"></div>
</div>
<div class="ratingHolder"></div>

3. Set up the star rating system.

var settings =[{
    // initial rating value
    "rating":"4.3", 
    // max rating value
    "maxRating":"5", 
    // min rating value
    "minRating":"0.5", 
    // readonly mode?
    "readOnly":"no", 
    // custom rating symbols here
    "starImage":"./star.png", 
    "emptyStarImage":"./starbackground.png", 
    // symbol size
    "starSize":"16", 
    // step size for fractional rating
    "step":"0.5"
}];

4. Render the star rating system on the page. Done.

rateSystem("ratingSystem", mySettings, function(rating, ratingTargetElement){
  ratingTargetElement.parentElement.parentElement.getElementsByClassName("ratingHolder")[0].innerHTML = rating;
});
