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?

how would you keep track of the votes without a resource that is accessible by all users (i.e. a server)? — Neil S, Aug 23 '13 at 20:57

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

That wouldn't work to show the total number of +1 votes because it would be stored locally on the clients. – Tjofras Aug 23 '13 at 21:04

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

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).
