I am developing an application using AngularJS. I want to update meta tags on route change.
How can I update meta tags in AngularJS which can be shown in "view source" on the page?
here is a HTML code -
<!DOCTYPE html>
<html ng-app="app">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="fragment" content="!" />
<meta name="title" content="Test App">
<meta name="description" content="Test App">
<meta name="keywords" content="Test,App">

<html ng-app="app">
<title ng-bind="metaservice.metaTitle()">Test</title>
<meta name="description" content="{{ metaservice.metaDescription() }}" />
<meta name="keywords" content="{{ metaservice.metaKeywords() }}" />
<script>
var app = angular.module('app',[]);
app.service('MetaService', function() {
var title = 'Web App';
var metaDescription = '';
var metaKeywords = '';
return {
set: function(newTitle, newMetaDescription, newKeywords) {
metaKeywords = newKeywords;
metaDescription = newMetaDescription;
title = newTitle;
},
metaTitle: function(){ return title; },
metaDescription: function() { return metaDescription; },
metaKeywords: function() { return metaKeywords; }
}
});
app.controller('myCtrl',function($scope,$rootScope,MetaService){
$rootScope.metaservice = MetaService;
$rootScope.metaservice.set("Web App","desc","blah blah");
});
</script>
<body ng-controller="myCtrl"></body>
