How To Do Auto Search Using JavaScript

In this code we will tackle about Auto Search using JavaScript. The program will enable to automatically search a row data. You are free to modify, and use this code. To learn more about this, just follow the steps below.

Getting started:

First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design

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">
        <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
        <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
    <nav class="navbar navbar-default">
        <div class="container-fluid">
            <a class="navbar-brand" href="">Sourcecodester</a>
    <div class="col-md-3"></div>
    <div class="col-md-6 well">
        <h3 class="text-primary">Auto Search Using JavaScript</h3>
        <hr style="border-top:1px dotted #ccc;"/>
        <div class="col-md-4">
            <div class="form-group">
                <label>Enter a name</label>
                <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="autoSearch()" class="form-control"/>
        <table class="table table-bordered">
            <thead class="alert-info">
                    <th>Member List</th>
            <tbody id="result"></tbody>
        <ul class="list-group" id="list"></ul>
<script src="js/script.js"></script>

Creating the Script

This code contains the script of the application. The code will automatically search a specific keyword. 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 members = ['Tony Stark', 'Jin Mori', 'Luke Cage'];
function displayMember(){
        if(a < b){
            return -1;
        if(a > b){
            return 1;
        return 0;
    data = "";
    for(var i=0; i < members.length; i++){
        data += "<tr><td>"+members[i]+"</td></tr>";
    document.getElementById('result').innerHTML = data;
function autoSearch(){
    var search=document.getElementById('search').value.toLowerCase();
    var parent=document.getElementById("result");
    var children=parent.getElementsByTagName('tr');
    for(var i=0; i<children.length; i++){
        var keyword=children[i].innerText;
            children[i].style.display = "none";
