    <p><strong>What i want to do:</strong><br> Simply send some data (json for example), to a node.js http server, using jquery ajax requests.</p> <p>For some reason, i can't manage to get the data on the server, cause it never fires the 'data' event of the request.</p> <p><strong>Client code:</strong></p> <pre><code>$.ajax({ url: server, dataType: "jsonp", data: '{"data": "TEST"}', jsonpCallback: 'callback', success: function (data) { var ret = jQuery.parseJSON(data); $('#lblResponse').html(ret.msg); }, error: function (xhr, status, error) { console.log('Error: ' + error.message); $('#lblResponse').html('Error connecting to the server.'); } }); </code></pre> <p><strong>Server code:</strong></p> <pre><code>var http = require('http'); http.createServer(function (req, res) { console.log('Request received'); res.writeHead(200, { 'Content-Type': 'text/plain' }); req.on('data', function (chunk) { console.log('GOT DATA!'); }); res.end('callback(\'{\"msg\": \"OK\"}\')'); }).listen(8080, '192.168.0.143'); console.log('Server running at http://192.168.0.143:8080/'); </code></pre> <p>As i said, it never gets into the 'data' event of the request.</p> <p><strong>Comments:</strong><br> 1. It logs the 'Request received' message;<br> 2. The response is fine, im able to handle it back on the client, with data;</p> <p>Any help? Am i missing something?</p> <p>Thank you all in advance.</p> <p><strong>EDIT:</strong><br> Commented final version of the code, based on the answer:</p> <p><strong>Client code:</strong> <br></p> <pre><code>$.ajax({ type: 'POST' // added, url: server, data: '{"data": "TEST"}', //dataType: 'jsonp' - removed //jsonpCallback: 'callback' - removed success: function (data) { var ret = jQuery.parseJSON(data); $('#lblResponse').html(ret.msg); }, error: function (xhr, status, error) { console.log('Error: ' + error.message); $('#lblResponse').html('Error connecting to the server.'); } }); </code></pre> <p><br> <strong>Server code:</strong><br></p> <pre><code>var http = require('http'); http.createServer(function (req, res) { console.log('Request received'); res.writeHead(200, { 'Content-Type': 'text/plain', 'Access-Control-Allow-Origin': '*' // implementation of CORS }); req.on('data', function (chunk) { console.log('GOT DATA!'); }); res.end('{"msg": "OK"}'); // removed the 'callback' stuff }).listen(8080, '192.168.0.143'); console.log('Server running at http://192.168.0.143:8080/'); </code></pre> <p><br> Since i want to allow Cross-Domain requests, i added an implementation of <a href="http://en.wikipedia.org/wiki/Cross-Origin_Resource_Sharing">CORS</a>.</p> <p>Thanks!</p>

    2. CO@Eric i have a button firing the ajax call. It's working fine, since i get the response data on the client. My problem is getting the request data on the server, which i believe it's because the 'data' event is not firing, and i don't know why.

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).
