In this tutorial we will create a Simple Star Rating using JavaScript. JavaScript is a scripting or programming language that allows you to implement complex things on web pages. It is widely used in designing a stunning website. It is an interpreted programming language that has the capabilities of Object-Oriented.

So Let's do the coding...

Getting started:

This is the link for the bootstrap that has been used for the layout of the calculator https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. This code will render application and display the form. To create this just write these block of code inside the text editor and save this as index.html.

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
                <link rel="stylesheet" type="text/css" href="fontawesome/css/all.css" />
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="continer-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com" target="_blank">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">JavaScript - Simple Star Rating</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-3"></div>
                <div class="col-md-6">
                        <div>
                                <h3>Rating:</h3>
                                <span id="1" style="font-size:45px; cursor:pointer;"  class="fa fa-star" onmouseover="startRating(this)" startRating="starmark(this)" ></span>
                                <span id="2"  style="font-size:45px; cursor:pointer;" class="fa fa-star" onmouseover="startRating(this)" startRating="starmark(this)"></span>
                                <span id="3"  style="font-size:45px; cursor:pointer;" class="fa fa-star" onmouseover="startRating(this)" startRating="starmark(this)"></span>
                                <span id="4"  style="font-size:45px; cursor:pointer;" class="fa fa-star" onmouseover="startRating(this)" startRating="starmark(this)"></span>
                                <span id="5"  style="font-size:45px; cursor:pointer;" class="fa fa-star" onmouseover="startRating(this)" startRating="starmark(this)"></span>
                        </div>
                        <br />
                        <div class="form-group">
                                <h3>Review:</h3>
                                <textarea id="review" class="form-control" style="resize:none; height:100px;"></textarea>
                        </div>
                        <center><button class="btn btn-success" onclick="result()">SUBMIT</button></center>
                        <div id="result"></div>
                </div>
        </div>
<script src="js/script.js"></script>    
</body>
</html>

Creating the Script

This code contains the script of the application. This code will display the review and rating of the users. To do this just copy write the code as shown below inside the text editor and save it as script.js.

var count = 0;
 
function result(){
        if(count != 0){
                document.getElementById('result').innerHTML = 
                "<h4>Rating: <label class='text-primary'>" + count + "</label></h4>"
                + "<h4>Review</h4>"
                + "<p>"+document.getElementById("review").value+"</p>";
        }else{
                
        }
}
 
function startRating(item){
        count=item.id[0];
        sessionStorage.star = count;
        for(var i=0;i<5;i++){
                if(i < count){
                        document.getElementById((i+1)).style.color="yellow";
                }
                else{
                        document.getElementById((i+1)).style.color="black";
                }
        }
}

2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
