Hi All,
I have a web application that calls an AjaxMethod every 1min based on a javascript timer. It appears that every time I call this ajax method, IE uses more memory.
My function goes like.. - function ajaxFunction() {
-
-
var xmlHttp;
-
xmlHttp = new XMLHttpRequest();
-
xmlHttp.open("GET","./currentActivityReport.do?action=RefreshCurrentActivity&"+parameter,true);
-
xmlHttp.onreadystatechange=function() {
-
-
if(xmlHttp.readyState==4) {
-
-
var myspan = document.getElementById('myspan');
-
var table = document.getElementById("Table");
-
myspan.removeChild(table);
-
table = null;
-
var newspan = document.createElement('span');
-
newspan.setAttribute("id","Table");
-
myspan.appendChild(newspan);
-
document.getElementById("Table").innerHTML=xmlHttp.responseText;
-
xmlHttp.onreadystatechange=function() {};
-
xmlHttp.abort();
-
}
-
}
-
-
xmlHttp.send("");
-
}
If any knows about the problem please let me know..

The innerHTML is over writting html and not releasing it from memory. You will have to look for alternatives to innerHTML.
A JavaScript framework such as the MochiKit is free and can handle your ajax requests for you and resolve all browser incompatabilies .
I have not done this myself yet; so I cannot help you any further.

Hi
I have an .Net application which processes thousands of Xml nodes each

within a loop (like if or for). E.g.

Hi,
Reading the Yahoo! UI AJAX library, there is a unique workaround for an
apparent IE 6 memory leak with binding a function to
onreadystatechange. Instead of binding a function to
onreadystatechange, the library polls the readystate of the request
object until it becomes 4. Then it calls the handler function. This
polling seems like a lot of work but maybe is a good approach? If bad
then what is better? Another person asked about this...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
