JavaScript - Simple Data Filter Using AngularJS

Submitted by razormist on Friday, May 24, 2019 - 11:02.

In this tutorial we will create a Simple Data Filter Using AngularJS. This code will filter any data that have been inputted by the user. The code itself use AngularJS directives that has a built-in filter function by just adding a filter function with a ng-model value in the ng-repeat table. This a user-friendly program feel free to modify and use it to your system. We will be using AngularJS as a framework which has additional custom HTML attributes embedded into it. It can interprets those attributes as directives to bind inputted parts of the page to a model that represent as a standard JavaScript variables.

Getting Started:

First you have to download Bootstrap, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/. And, this is the link for the AngularJS https://angularjs.org/.

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into you text editor, then save it index.html.

<!DOCTYPE html>
<html lang="en" ng-app="myModule">
        <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 ng-controller="myController">
        <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 Data Filter Using AngularJS</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="form-inline pull-right">
                        <input type="text" class="form-control" ng-model="filter" placeholder="Search here..."/>
                </div>
                <br />
                <br />
                <table class="table table-bordered">
                        <thead class="alert-info">
                                <tr>
                                        <th>Firstname</th>
                                        <th>Lastname</th>
                                        <th>Gender</th>
                                </tr>
                        </thead>
                        <tbody>
                                <tr ng-repeat="member in members | orderBy: 'lastname' | filter: filter">
                                        <td>{{member.firstname}}</td>
                                        <td>{{member.lastname}}</td>
                                        <td>{{member.gender}}</td>
                                </tr>
                        </tbody>
                </table>
        </div>
<script src="js/angular.js"></script>   
<script src="js/script.js"></script>    
</body>
</html>

Creating the Main Function

This code contains the main function of the application. This code will automatically filter any data that have been inputted. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js directory.

var app = angular.module("myModule", [])
                                        .controller("myController", function($scope){
                                                var members = [
                                                        {firstname: "John", lastname: "Smith", gender: "Male"},
                                                        {firstname: "Johhny", lastname: "Sins", gender: "Male"},
                                                        {firstname: "Claire", lastname: "Temple", gender: "Female"}
                                                ];
                                                
                                                $scope.members = members;
                                        });

There you have it we successfully created a Simple Data Filter using AngularJS. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!!
