AngularJS format JSON string output
I have an AngularJS application, which collects data from input, transforms a model into a string using JSON.stringify() and lets a user edit this model in such a way that input fields get updated if the <textarea> element is updated and vice versa. Some kind of two-way binding :)
The problem is that the String itself looks ugly and I would like to format it so it looks like this:
And not like it looks now:
Any ideas how this can be accomplished? If you need some additional info - don't hesitate asking. Every answer is highly appreciated and answered immediately.
Thank you.
P.S. I guess this should be some kind of directive or a custom filter. Data itself SHOULD NOT be changed, only the output.
Answer
Angular has a built-in filter for showing JSON
<pre>{{data | json}}</pre>
Note the use of the pre-tag to conserve whitespace and linebreaks
Demo:
angular.module('app', [])
.controller('Ctrl', ['$scope',
function($scope) {
$scope.data = {
a: 1,
b: 2,
c: {
d: "3"
},
};
}
