Re: how to save json document into couchdb using javascript

Hi,

CouchDB is using JSON as document format, only that it needs to be
stringified to be compatible with AJAX POST method (at least this is the
recommendation from W3C). That means, using plain JavaScript, it should
look like this:

<script type="text/javascript">
> function saveCouchDBDoc(myJSON)
> var xmlhttp;
> var responseJSON;
> if (window.XMLHttpRequest)
>   {// code for IE7+, Firefox, Chrome, Opera, Safari
>   xmlhttp=new XMLHttpRequest();
>   }
> else
>   {// code for IE6, IE5
>   xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
>   }
> xmlhttp.onreadystatechange=function()
>   {
>   if (xmlhttp.readyState==4 && xmlhttp.status==200)
>     {
>     responseJSON=JSON.parse(xmlhttp.responseText); // if you are sure it
> returns a JSON string
>     }
>   }
> xmlhttp.open("POST","/datadase_name",true);
>
> xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
> xmlhttp.send("data="+JSON.stringify(myJSON));
> }
> </script>

Just take care for x-origin permissions if you use another web server.

Another option would be using directly JSON by setting the header
"Content-Type" to "application/json" and data to myJSON.

I admit I never tried any of them directly with CouchDB web server because
I was using two-layer design (CouchDB + dedicated web server with reverse
proxy and/or middleware), so, the code is not 100% error free (e.g., if
"/database_name" doesn't work, I think you can use
"/_utils/database.html?database_name"). But, at least, it gives you a
starting point.

Don't forget about giving a name to the document and providing the revision
number if you already have a document.

Hi Lenin,

Let's shift this conversation to the user@ mailing list where it's
more appropriate.

You'll need to share some of your non-working code with us, to better
understand where you are stuck --  e.g. on http://friendpaste.com/ or
on gist.github.com.

The issue you are having is that the call you're trying to make is
forbidden because they're different origins. I suggest you google for
an explanation in your native language, it will help a lot.

There are many ways of working around this, but the simplest way in
CouchDB is simply to serve the HTML & the database from the same
origin. This is way cool. There is a tool called couchapp which
synchronises files on disk with design documents in your database and
makes this really really simple.

TL;DR:

- download & install couchapp for your platform[1]
- then `couchapp generate myapp`
- put your html files (like index.html and js files) in "myapp/_attachments/"
- `couchapp push` will send these new files to your localhost:5984 (in
admin party) into a new db called myapp
- visit the new url and play

You can use the same code that futon does jquery.couch.js[2] and check
in the test suite for examples on how to hook all of that together.
Running the test suite in the chrome developer tools gives a very good
overview of how this stuff should work.

Useful docs for jquery.couch.js[2] and test suite[3] follow.

A+
Dave

Do you have the same IP and the same port for both requester and receiver?
