});
});
app.post('/', function (req, res) {

});
});
});
**html code**
<div align="center" ng-controller="FormCtrl">
<form name="form" ng-submit="submitForm()" novalidate>
<table>
<tr><td>Name:</td>
<td>
<input id="firstname" type="text" ng-model="regform.firstname" name="firstname" required="" />

<td>
<div ng-show="form.$submitted || form.firstname.$touched">
<div ng-show="form.firstname.$error.required">Enter your name.</div>
</div>
</td>
</tr>
<tr>
<td>Last Name: </td>
<td>
<input id="lastname" name="lastname" type="text" ng-model="regform.lastname" required>
</td>
<td>
<div ng-show="form.$submitted || form.lastname.$touched">
<div ng-show="form.lastname.$error.required">Enter your Last name.</div>
</div>
</td>
</tr>
<tr>
<td>E-mail:</td>
<td><input id="email" type="email" ng-model="regform.email" name="uEmail" required="" /></td>
<td>
<div ng-show="form.$submitted || form.uEmail.$touched">
<span ng-show="form.uEmail.$error.required">Enter your email.</span>
<span ng-show="form.uEmail.$error.email">This is not a valid email.</span>
</div>
</td>
</tr>
</table>
<input type="button" ng-click="reset(form)" value="Reset" />
<input type="submit" ng-disabled="!form.$valid" value="Save" />
<p id="hu"></p>
</form>
</div>
<%if(data) {%>
<h1>Users</h1>
<% data.forEach(function(user){ %>
<br>
<table>
<tr><td>Name: </td><td><%= user.name %> <%= user.lastname %></td></tr>
<tr><td>Email: </td><td><%= user.email %></td></tr>
</table>
<% }) %>
<% } %>
</body>
</html>
**javascript**
var result;
var app = angular.module('formExample', []);
app.controller('FormCtrl', function ($scope, $http) {
$scope.data = {};
$scope.submitForm = function() {
formData = $scope.regform;
console.log("posting data....");
var request = $http({ url: '/',data: $scope.regform, method: 'post' });
console.log(formData);
};
});
here I can save data on mongodb using expressjs. I need to display data after form submission. Here nothing is displaying after form submission. How to display that saved content in html using embedded Javascript.

What you'll want to do is change your res.render() call to do something like this:
res.render('index', {
data: docsData,
title: 'AJT Family',
header: 'Some Users',
body: req.body, // This is your form data as a JSON object.
});
Then, in your index template, you'll have access to your form data to display however you want, if you're using Jade, for instance, you might want to say like:
h1 Data!
p #{body}
