Any Javascript example for conenction to the couchDB server

["Wu,Shaolong" <SW...@mdanderson.org>]

Hi,

I am really at the beginning. I would like to use the couch.js at the client site. Couch.js defines the CouchDB. But I did not find anything that specify the host information. How do you specify the server host information?


Here is a simple thing I want to test first:

I want to use the couch.js. First connect to the server, then create a database, then insert some doc.

<script type="text/javascript">

        function testCouchDB()
        {

            CouchDB.host = "127.0.0.1:5984"; // I know this is wrong, but how do I do that?

            var db = new CouchDB("test", {"X-Couch-Full-Commit":"false"});


            db.createDb();

            var nc = {_id:"NC", cities:["Charlotte", "Raleigh"]};
            var ma = {_id:"MA", cities:["Boston", "Lowell", "Worcester", "Cambridge", "Springfield"]};
            var fl = {_id:"FL", cities:["Miami", "Tampa", "Orlando", "Springfield"]};

            db.save(nc);
            db.save(ma);
            db.save(fl);

        }
        </script>

The most basic answer is that for JavaScript clients, the host will usually be the same as the host the HTML file was served from. The same-origin rules require it to be this way.

See the source code of Futon for examples of using jquery.couch.js (better than couch.js for most purposes).

There are lots of examples of using CouchDB from the browser, but the Futon source code is the easiest to get. See: 

http://github.com/apache/couchdb/tree/trunk/share/www

Hope this helps,
Chris
