So let's do the coding.

Before we get started:

This 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 list and the search box. 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 Create Filter Search List in JavaScript</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-6">
                        <div class="form-group">
                                <div class="input-group">
                                        <div class="input-group-addon"><span class="glyphicon glyphicon-search"></span></div>
                                        <input type="text" id="search" placeholder="Search here..." onkeyup="searchResult()" class="form-control"/>
                                </div>
                        </div>
                        <ul class="list-group" id="list"></ul>
                </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 try to filter the entered result in the list. To do this just copy and write these block of codes inside the text editor and save it as script.js.

let name_list = ['Steve', 'Bruce', 'Tony', 'Rimuru', 'Millim', 'Leon', 'Takamitchy', 'Draken'];
        
displayList();
 
 
function searchResult(){
        let search = document.getElementById('search').value.toLowerCase();
        let target = document.getElementById("list");
        let list = target.getElementsByTagName('li');
        for(var i=0; i < list.length; i++){
                let text = list[i].innerHTML;
                if(text.toLowerCase().indexOf(search) > -1){
                        list[i].style.display = "";
                }else{
                        list[i].style.display = "none";
                }
        }
}
 
function displayList(){
        name_list.sort(function(a,b){
                if(a < b){
                        return -1;
                }
 
                if(a > b){
                        return 1;
                }
 
                return 0;
        });
        
        data = "";
        
        for(var i=0; i < name_list.length; i++){
                data += "<li class='list-group-item'><a href='https://www.google.com/search?q="+name_list[i]+"'>"+name_list[i]+"</a></li>";
        }
        
        document.getElementById('list').innerHTML = data;
}

In the code above we just simply first create a variable that will handle the array of the list. Then we create a new method called displayList(), this function will sort out the filtered data that we enteredfrom our displayed list. And last we will create a method called searchResult(). This function will bind the search box and will display a result base on the entered keyword.
