Ajax page not getting refreshed in IE

[vjayis]

hi

i have a php page in which i have included few tabs links like

games, news,entertainm ent etc.,

when i click the tablink an ajax page is loaded below.
In that ajax page several pages(iframes) are loaded inside the tables, such that it contains three tables in a row.
each table contains different pages loaded through iframes,
and an close button is available so that we can close the unwanted tables(containi ng frames).

"i hav done similar to igoogle drag and drop portion without drag option"

so if we close an table the page name is stored in the database and it is not diaplayed.,

The problem is when i close the tables(page containing iframes) its getting closed and the values are stored correctly in the database., but after that if i click the same tablink the ajaxpage gets loaded along with the closed tables(which i have closed).
i,e the page gets loaded with the old datas without getting the refreshed values from the database.,

it works well in firefox.,

Can anyone help me.,

regards

The page is probably getting cached.

You'll need to get a unique page, so add something like

"&cache="+(new Date()).getTime()

to the end of the URL.

Post your current code.

Here is my code:

<script type="text/javascript">

function ajaxFunction1(action,id,uname,tablename)
{
var xmlHttp;
try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    try
      {
      xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
    catch (e)
      {
      alert("Your browser does not support AJAX!");
      return false;
      }
    }
  }
xmlHttp.onreadystatechange=function()
{ 
 if(xmlHttp.readyState==1)
 {
 	
 }
 if(xmlHttp.readyState==4)
 { 
	document.getElementById("ajax1").innerHTML=xmlHttp.responseText;
 }
}

xmlHttp.open("GET","includes/ajaxpage.php?action="+action+"&id="+id+"&uname="+uname+"&table="+tablename,true);
xmlHttp.send(null);

}
</script>

so when i close an table (containing iframe)., four variables are passed to the ajax page and the same page gets loaded without the closed table. the closed table name is stored in the database such that it is not diaplayed.,

very urgent ., help me in this.,

thanks

Hi

i m with the same problem once again.,

i had added the given code by u to all the ajax url's that are contained in my page.,
but still i m having problem.,

when i select an tab(example:gam es) the tables which comes under the games category are displayed under the tabnames.
Note:each table contains frame in which the particular game is loaded.

if i click on another tab(example:new s) before the tab(containing games) gets loaded-> mismatch occurs.,
the titles of the tables gets changed but the contents(frames ) didnt get changed.,

and i had added the the code given by u to my page redirecting.,

here is my code.,

var dd=(new Date()).getTime();
tabs.open("GET","tabselection.php?tabname="+tab+"&data1="+data1+"&data2="+data2+"&data3="+data3+"&cache="+dd,true);
tabs.send(null);

any other solution to get rid of this.,

regards

That's a slightly different problem. You're reusing the same object which is still in use, so when you make another request whilst one is still ongoing, you need to abort the previous request. You can do that by checking that the ajax request object has not completed. If it hasn't, abort using the abort() method.

if i click on another tab(example:new s) before the tab(containing games) gets loaded-> mismatch occurs.,
the titles of the tables gets changed but the contents(frames ) didnt get changed.

Apparently, you are changing the name of the tab and then sending the Ajax request. Instead, you need to run the change-name part of code in the onreadystatecha nge function, after you receive the xmlHttp response.

sorry to say this.,

i am unable to implement the ideas given by you.,

so could you explain me briefly with some coding.,

here is my full script used to load the another page while selecting another tab.,

<script type="text/javascript">

function tabs123(tab,type,data3,data4)
{
try
  {
  tabs=new XMLHttpRequest();
  }
catch (e)
  {
  try
    {
    tabs=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    try
      {
      tabs=new ActiveXObject("Microsoft.XMLHTTP");
      }
    catch (e)
      {
      alert("Your browser does not support AJAX!");
      return false;
      }
    }
  }
def5=document.getElementById("defaulthid").value;
tabs.onreadystatechange=function()
{ 
 if(tabs.readyState==1)
 {
 	document.getElementById("tabimage").style.display="block";
 }
if(tabs.readyState==4)
 { 
	document.getElementById("tabimage").style.display="none";
	document.getElementById("tabs").innerHTML=tabs.responseText;
 }
}
var dd=(new Date()).getTime();
tabs.open("GET","tabselection.php?tabname="+tab+"&type="+type+"&data3="+data3+"&data4="+data4+"&cache="+dd,true);
tabs.send(null);

}
</script>

<a style="cursor:pointer" onClick="tabs123('games','<? echo $tablename;?>','<? echo $data3;?>','<? echo $data4;?>')" >Games</a>
			<a  style="cursor:pointer" onClick="tabs123('news','<? echo $tablename;?>','<? echo $data3;?>','<? echo $data4;?>')" >news</a>

<div id="tabs"></div>

There are two ways to solve this. One way is to check if the ajax object's readyState is 0 (uninitialized) . If it's not, abort the request.

The second way is to just swap the open() and onreadystatecha nge lines, i.e. place the open() call before the onreadystatecha nge event handler.

i tried out the second way as u suggested.,

but i also like to know how to implement through first method u r saying.,
i am stuck., how to implement it.,
here i check whether the object's readystate is 0.,

if(xmlHttp.readyState==0)
{
}

i dont know what to do within this., to abort the request.,

and if the request is aborted what will happen., the present operation will gets aborted or already running(previou s) operation will get aborted??

I assume that worked then?

but i also like to know how to implement through first method u r saying.,
i am stuck., how to implement it.,

Something like this:

if(xmlHttp.readyState!=0)
{
    xmlHttp.abort();
}

and if the request is aborted what will happen., the present operation will gets aborted or already running(previou s) operation will get aborted??

There's only one Ajax object, so the previous one will get aborted to allow you to use it for the current request.
