AngularJS | json Filter - GeeksforGeeks

The json filter in AngularJs is used to convert a JavaScript object into a JSON. string.JavaScript object that we are using can be of any kind of JavaScript Object.

Syntax:

    {{ object | json : spacing }}

Where json is used to specifies that object should be displayed in JSON format and spacing is an optional parameter with default value 2 that specifies the number of spaces per indentation.

Example 1:
This example will display the marks of student in JSON

<!DOCTYPE html> 
<html> 
    <head> 
<script src= 
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"> 
</script> 
    </head> 
<body> 
  
<div ng-app="result" ng-controller="resultCtrl"> 
  
<h1>Result:</h1> 
  
<pre>{{marks | json}}</pre> 
  
</div> 
  
<script> 
var app = angular.module('result', []); 
app.controller('resultCtrl', function($scope) { 
$scope.marks = {  
        "Math" : 98, 
        "Computer" : 93, 
        "Physics" : 95, 
        "Chemistry" : 95, 
        "English" : 74 
    }; 
}); 
</script> 
  
</body> 
</html> 

Output :
