So let's do the coding.

Before we get started:

Here is the link for the template that i used for the layout design https://getbootstrap.com/.

Creating The Interface

This is where we will create a simple interface for our application. This code will only html form and the pyramid object. To create this simply copy and write it into your text editor, then save it 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" />
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">How to Generate Pyramid Shape Object</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-4">
                        <form>
                                <div class="form-group">
                                        <label>Enter the pyramid size</label>
                                        <input type="number" id="row" class="form-control" />
                                </div>
                                <button type="button" class="btn btn-primary btn-block" onclick="generatePyramid();">Generate</button>
                        </form>
                </div>
                <div class="col-md-2"><h2>RESULT</h2></div>
                <div class="col-md-6">
                        <div id="result"></div>
                </div>
        </div>
<script src="script.js"></script>       
</body> 
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will generate a pyramid shape object after submitting the form. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function generatePyramid(){
        var row=document.getElementById('row').value;
        
        if(row ==""){
                alert("Please enter something first!");
        }else{
                var html="";
                for(var i=1; i<=row; i++){
                        for(var k=1; k<=(row-i); k++){
                        
                                html+="&nbsp;";
                        }
                        
                        for(var j=1; j<=i; j++){
                                html+="| ";
                        }
                        
                        html+="<br />";
                }
                
                document.getElementById('result').innerHTML=html;
        }
}

This code above only create one method called generatePyramid(), this function will generate a pyramid shape object after you submit the size number. This method is looping to loop through the element and positioning in a pyramid pattern
