    <p>Your code is almost right but on your code sample you have </p> <pre><code>console.log(data[0].id) </code></pre> <p>the <strong>data</strong> object has <strong>no</strong> property <strong>id</strong> so if you only have </p> <pre><code>console.log(data[0]) </code></pre> <p>there you have a response like </p> <pre><code>{ a: '1' } </code></pre> <p>therefore you can access the property <strong>a</strong> by doing</p> <pre><code>console.log(data[0].a); </code></pre> <p><strong>UPDATED Updated with a full example</strong></p> <p>One more thing is that you are using <strong>eval</strong> and node comes with <strong>JSON.parse</strong> bundle with it so the snippet below is how i made it work </p> <p>File: app.js</p> <pre><code>var sys = require("sys"), http = require("http"), url = require("url"), path = require("path"), fs = require("fs"); http.createServer(function(request, res) { var parsed_url = url.parse(request.url); var uri = parsed_url.pathname; if(uri === "/test"){ res.writeHead(200, {'Content-Type': 'text/javascript'}); request.addListener('data', function (chunk) { // removed this - eval("(" + chunk + ")"); var data = JSON.parse(chunk); console.log(data[0].a); }) request.addListener('end', function() { console.log('end triggered'); res.write("Post data"); res.end(); }); } else if(uri === "/") { fs.readFile("./index.html",function(err, data){ if(err) throw err; res.writeHead(200, {'Content-Type': 'text/html'}); res.end(data); }); } }).listen(8080); </code></pre> <p>On the same directory create a file index.html with the following: </p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script type="text/javascript" charset="utf-8"&gt; var myhttp = new XMLHttpRequest(); var url = "http://localhost:8080/test"; var data = [{"a":"1"},{"b":"2"},{"c":"3"}]; var dataJson = JSON.stringify(data); myhttp.open('POST', url, true); myhttp.send(dataJson); myhttp.onreadystatechange = function() { if ((myhttp.readyState == 4) &amp;&amp; (myhttp.status == 200)){ alert(myhttp.responseText); } else if ((myhttp.readyState == 4) &amp;&amp; (myhttp.status != 200)) { console.log("Error in Connection"); } } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>That is a complete working example of what you want.</p> <p>With regards to the same origin policy issues you were having is mainly due to the fact that you cant POST data between 2 different domains via ajax unless you use some tricks with iframes but that is another story.</p> <p>Also i think is good for anyone to understand the backbone of a technology before moving into frameworks so fair play to you.</p> <p>good luck</p>

    1. COhey, it works on firefox when i replaced the header with res.writeHead(200, { 'Content-Type': 'text/javascript', 'Access-Control-Allow-Origin' : '*' }); but on chrome i am getting errorRequest header field Content-Type is not allowed by Access-Control-Allow-Headers. you have any clue how to resolve in chrome.

    2. COAre running the examples on the same host and port ? If not you must use **jsonp** when making your ajax request.

    3. COThanks Joao , Actually problem was of permissions for request headers that need to be set for webkit based browsers, so doing Access-Control-Allow-Headers - 'Content-type' in response headers solved this.As webkit breaks down the ajax request in two parts..so this solved by seeing webkit cors :-)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
