Clientside Heart Vote

Question

Is there a way to implement a simple Heart vote(just +1 vote with counter without ability to vote more than once) using only Javascript / jQuery and HTML5 data attributes, other HTML5 APIs, without any serverside stuff?

Answer 1

You can use localStorage to record that client has voted. Something like this:

localStorage.setItem('voted', true);

To check if client voted before:

var voted = localStorage.get item('voted');

Update:

As you need a counter, you may try one of BAAS (backend-as-a-service) services, such as parse.com or kinvey.com

Answer 2

No, there isn't. You need a server to store all the responses.

Answer 3

You need to store it in some type of database. So if you don't have any server side code that does this you need to find a service that will do it for you. (I don't know if one exists but i wouldn't be surprised if there did).
