Problem with back button and AJAX

[marfola]

I have an Ajax application and I want to take control of the back button. I have implemented a Javascript, but it runs correctly only on Firefox. In IE7 I got some problems.

My script runs as follow:
- when I click from a tab to another of the same page I update the sub-content via Ajax and I change my url adding hash parameters (using window.location .hash).
- when I get an url with hash parameters I parse it and I send the correct sub-content to the page.

Everything manage correctly in Firefox. If I click on the browser back button I can always get the right url (with hash parameters), then I parse it and send the correct sub-content to the page.

In I.E. 7.0 if I click from a tab to another of the same page, the history browser doesn't push nothing. It contains always the first entry of my page (without hash parameters), while the browser bookmark got the correct url.

Could someone help me to find the problem?

Can you post your code or a link to a test page that demonstrates the problem?

Here's my code:

[CODE=javascript]var lastSavedHash = "";

/* function called when user click on tab AJAX button */
function makeHash(mode)
{
window.location .hash = mode;
lastSavedHash = window.location .hash;
return true;
}

/* function who checks the hash values and send the correct sub-content to the page.*/
function handleHash()
{
if ( window.location .hash != lastSavedHash )
{
currentHash = window.location .hash;

mode = lastSavedHash.r eplace("#", "");

url = window.location .href;
querytext = url.split("/");

if (mode != querytext[5])
<callAjaxUpdate SubContent(mode )>;
}
else
return '';
}


/* function called onload event and every x seconds Call handleHash function*/
function checkHash() {
handleHash();
setInterval("ha ndleHash()", 200);
}[/CODE]

How do you call makeHash()?

[marfola]

I call makeHash in the getAjaxContent function, i.e. every time the sub-content change after user click on a tab button.
