XMLHttpRequest response is null in Javascript -

-

when trying execute xmlhttprequest, response returned server (as checked in fiddler), xhr.getallresponseheaders() returns null , throws exception.

is because of "same origin policy"? can please suggest how resolve issue?

code: using datajs.codeplex.com open source code:

                xhr.onreadystatechange = function () {                 if (xhr === null || xhr.readystate !== 4) {                     return;                 }                  // workaround xhr behavior on ie.                 var statustext = xhr.statustext;                 var statuscode = xhr.status;                 if (statuscode === 1223) {                     statuscode = 204;                     statustext = "no content";                 }                  var headers = [];                 var responseheaders = xhr.getallresponseheaders().split(/\r?\n/);

resource located in different domain. accessing http://odata.netflix.com/v1/catalog/genres

to circumvent same-origin policy use js call php script gets contents of external url , echo results.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...
