I'm having a peculiar error with IE11 and ajax. For nearly all the requests I make using the code below, everything is fine, yet when I try use in conjunction with a copy+paste method, it returns an Access is denied error. So to summarise

• This code works normally in most browsers for all functions I have written
• In IE 11 + Windows 8.1, it works in most cases, except when running a particular copy and paste function
• Interestingly, when using IE 11, but with a different Document mode such as 8, I still get the same error, even though it works natively in IE8 + Windows 7
• The error is 'Access is denied'

Here is the AJAX code:

function ajaxRequest(requestName,responseFunction,parameters) {
 var xmlhttp;
 if (requestName.length==0) return;
 if (window.XMLHttpRequest)  {
     xmlhttp=new XMLHttpRequest();
 } else {
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 }
 xmlhttp.onreadystatechange=function() {
     if (xmlhttp.readyState==4 && xmlhttp.status==200) {
        if(xmlhttp.responseText == 'Error') alert('Error processing request. Please refresh the page and try again');
        else if(xmlhttp.responseText != '') eval(responseFunction+"('"+xmlhttp.responseText+"')");
     }
 }
 var now = new Date();
 var url = "control/ajax.php?request="+requestName+"&parameters="+parameters+"&timestamp"+now;
 xmlhttp.open("GET",url,true);
 xmlhttp.send();
}

An example of a failure, had the following variables set:

requestName: "save_marksheet_mark" responseFunction: "update_save_marksheet_mark" parameters: [60962,1284,5]

Is there something wrong with this code? Is there a reason why IE11 would throw an error with this code, in particular circumstances?

• This isn't a cross domain request - var url = "control/ajax.php... It's requesting a page on the same site as the user is already visiting – Ben Commented Nov 12, 2014 at 16:44
• "yet when I try use in conjunction with a copy+paste method, it returns an Access is denied error" did you try the copy paste on it's own to see if that's where the "Access Denied" error is originating from? eliminate unnecessary code if possible. – Kevin B Commented Nov 12, 2014 at 16:48
• That was my initial thought, but the error is clearly on the xmlhttp.open line (as highlighted in the developer tools) - when I ment that out (as well as xmlhttp.send), there are no errors. – Ben Commented Nov 12, 2014 at 17:01
• Try putting the xmlhttp.open("GET",url,true) line above the xmlhttp.onreadstatchange declaration. – idbehold Commented Nov 12, 2014 at 17:23

This question appears to be getting a lot of views, so just in case anybody was wondering, I solved this problem by using a setTimeout() on the original AJAX call. E.g:

setTimeout(function() {
        ajaxRequest('save_mark','save_mark_pleted',[60962,1284,5]) 
    }, 1);

I'm assuming it's some kind of bug in IE. Just 1 millisecond was all it needed!

setTimeout(function() {
        ajaxRequest('save_mark','save_mark_pleted',[60962,1284,5]) 
    }, 1);

This did work for me for the first call after page load but later calls again started to show Access is denied error
