  1. PONot getting Response from ajax , getting into error function
    text
    copied!<p>I am working with ajax and node js for the first time. When I use the client to get response from node js it gets into the error function. On the other hand, when I directly call the url from the browser, I get the correct response from the server. This is an indication that something is wrong with the client side ajax request. </p> <p>This is my client code :</p> <pre><code>function fetch() { $.ajax({ type: 'POST', url: "http://127.0.0.1:8888", data: {data : 'India'}, dataType: 'json', success: function () { alert("hi"); //var ret = jQuery.parseJSON(data); //$('#q').html(ret.msg); }, error: function (jqXHR, textStatus, error) { console.log('Error: ' + error.message); alert("ERROR"); } }); </code></pre> <p>This is the server node.js code (part of it). The console.log msg get the correct values.</p> <pre><code>http.createServer(function(req, response) { console.log("Request received"); response.writeHeader(200, {"Content-Type": "application/json"}); req.on('data', function (chunk) { console.log(chunk.toString('utf8')); console.log(result[0].name); }); response.end(JSON.stringify({data:result})); }).listen(8888); </code></pre> <p>All the console.log in the server gets the correct values. That means the response is not reaching back when there is ajax request, but on directly writing 127.0.0.1:8888, I get correct response.</p> <p>The message on the console is :</p> <pre><code>XMLHttpRequest cannot load http://127.0.0.1:8888/. Origin null is not allowed by Access-Control-Allow-Origin. </code></pre> <p>Please someone help to fix this out. I have been on this for a day now.</p> <p>EDIT : Screen capture of the network tab. As you can see the server gets the request but the client does not get the response. This is done even after writing 'Access-Control-Allow-Origin' : '*'. <img src="https://i.stack.imgur.com/sDYAf.png" alt="enter image description here"></p>
