Getting started:

First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. 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"/>
        </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">JavaScript - Simple Remove Words From Paragraph</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-2"></div>
                <div class="col-md-8">
                        <form>
                                <div class="form-group">
                                        <label>Remove Word</label>
                                        <input type="text" id="content"/>
                                        <button type="button" onclick="removeWord();" class="btn btn-primary">Remove</button>
                                </div>
                        </form>
                        <p id="result"></p>
                </div>
        </div>
</body>
<script src="js/script.js"></script>
</html>

Creating the Script

This code contains the script of the application. This code will remove a word when the button is clicked. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.

var paragraph = "The question how knowledge should be defined is perhaps the most important and difficult of the three with which we shall deal.";
        
document.getElementById('result').innerHTML = paragraph;
 
 
var newParagraph = "";
 
 
function removeWord(){
        var content = document.getElementById('content');
        var word = content.value;
 
        if(content.value == ""){
                alert("Please enter something first!");
        }else{
                if(newParagraph == ""){
                        newParagraph = paragraph.replace(new RegExp(word, 'g'), "");
                }else{
                        newParagraph = newParagraph.replace(new RegExp(word, 'g'), "");
                }
                
                document.getElementById('result').innerHTML = newParagraph;
                
                content.value = "";
        }
}
