Google Maps API：如何使用户添加的标记成为永久标记？

Question

I am currently trying to create a map application which allows users to add their own pins. I want it to be an 'open' map where anyone with an account can add/edit pins on top of everyone else's.

With my limited knowledge of JavaScript, I have got to the point where anyone can add their pins, but they don't save (ie are removed once the application is reloaded). Only those I have put in manually (in the script) actually stick.

So, could anyone help me out?

How can I create some sort of 'database' (like in the custom map editor for google maps) which users can edit without having to actually put it in the code?

look at jStorage http://www.jstorage.info/

<script src="//code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="jstorage.js"></script>
<script>
   // Check if "key" exists in the storage
   var value = $.jStorage.get("key");
   if(!value){
       // if not - load the data from the server
       value = load_data_from_server()
       // and save it
       $.jStorage.set("key",value);
   }
</script>

Have two arrays saved by jStorage, lat and lng arrays, and then set markers by using a for loop and let it work through the arrays.
