rest - Javascript code using xhr is not working? -

below response server (as per google chrome rest-client):

below code snippet i'm using post info our server. want info xml ouput. keeping in mind concept of same origin policy uploaded piece of code onto our sever html page, not getting response.

is there wrong code or approach wrong?

<html> <head> <script type="text/javascript"> function gettoken() { var xmlhttp; var txt,x,i; if (window.xmlhttprequest) {// code ie7+, firefox, chrome, opera, safari xmlhttp=new xmlhttprequest(); } else {// code ie6, ie5 xmlhttp=new activexobject("microsoft.xmlhttp"); } alert("stage 1"); xmlhttp.onreadystatechange=function() { alert("stage 2"); if (xmlhttp.readystate==4 && xmlhttp.status==200) { alert("stage 3"); xmldoc=xmlhttp.responsexml; txt=""; x=xmldoc.getelementsbytagname("token"); alert("stage 4"); (i=0;i<x.length;i++) { txt=txt + x[i].childnodes[0].nodevalue + "<br />"; } document.getelementbyid("mydiv").innerhtml=txt; } } alert("stage 5"); xmlhttp.open("post","http://abc.mysite.com:9090/myapi/xxx",true); xmlhttp.send("op=login&pass=xxx"); } </script> </head> <body> <center><h2>userpreview:</h2></center> <br /> <div id="mydiv"></div> <br /> <button type="button" onclick="gettoken()">gettoken</button> <div data-role="footer" data-position="fixed" data-theme="a"><h4>ver: 1.1(17112)</h4> </div> </body> </html> <response><token>8768768768768768</token></response>

you have take business relationship that: ajax calls, can access same hostname (and port / scheme) page loaded from. same domain , same port:

how same-domain policy enforced?

in past utilize ie version, suppose possible compatibility issues:

try { xmlhttp = new activexobject("msxml2.xmlhttp"); } catch(e) { seek { xmlhttp = new activexobject("microsoft.xmlhttp"); }catch(e){}

i set code this:

var theurl="http://mysite.abc.com:8080/myapi/xxx" var data="op=login&pass=xxx"; http.open("post",theurl, true); http.onreadystatechange = function(){ }; xmlhttp.setrequestheader("content-type", "application/x-www-form-urlencoded"); xmlhttp.setrequestheader("content-length", data.length); xmlhttp.setrequestheader("connection", "close"); xmlhttp.send(data);

can't utilize jquery? much more efficient.

to create ajax call: http://api.jquery.com/jquery.ajax/

for example:

$.ajax({ url: "test.html", context: document.body, success: function(){ $(this).addclass("done"); } });

the sooner utilize jquery sooner work faster.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
