Introduction

Filter in Angular JS is a way that will help you to represent your data in View in a certain format. There are many inbuilt filters provided by Angular js that give us the way to format our data in View.  With these inbuilt filters, we can format & show our data in various ways.  Text can be shown in uppercase, lowercase. Date can be also represented in various formats.  All we need to do it is add a "|"  (pipe) after the data.

Example: {{ 'Hello World' | uppercase }}

We can also create custom filter to display our data in a particular way that we want. Let's see how we can create a custom filter. I am going to implement a custom filter, which reverses the input entered in a text box.

How to Create Custom Filters

Hide    Copy Code
//Initialize your ng-app

var myapp = angular.module('MyApp', []);

//Create a Filter

myapp.filter("reversetext", function() {

        //Defining the filter function

         return function(input) {

                 var result = "";

                 input = input || "";

                for (var i=0; i<input.length; i++) {

                       result = input.charAt(i) + result;

                 }

                return result;

         };

});

Now Use the Filter in your View with HTML

Hide    Copy Code
<body ng-app="MyApp">

       <input type="text" ng-model="text" placeholder="Enter text"/>

        <p>Filtered Reverse Input: {{ text | reversetext }}</p>

</body>
