AJAX Problem - Firefox and IE6 issue

violinandviola

I have just put 4 different ajax bits on this page:
http://jimpix.co.uk/default-ajax.asp

The ajax spits out chunks of images / news content, and users can view
the chunks via next / prev links.

When I first view the page in Firefox, there is a short delay while
the content first loads in the ajax sections.

When I first view the page in IE6, none of the ajax content appears to
start with. It only appears if I click a 'next' link.

Initially the body tag contained this, to fire off the 4 relevant
functions:
<body id="root" onload="sendReq uest(MyCurrentV ar + ',' +
MyCurrentCat); sendPhotoReques t(MyPhotoVar);
sendNewsRequest (MyNewsVar); sendWPRequest(M yWPVar)">

I then got rid of that, and used this instead:

window.onload = function()
{
sendRequest(MyC urrentVar + ',' + MyCurrentCat)
sendPhotoReques t(MyPhotoVar)
sendNewsRequest (MyNewsVar)
sendWPRequest(M yWPVar)
}

But I get the same result regardless.

Any advice much appreciated.

Thanks

Are these send*Request sync or async? Do not forget that the page is
not displayed until the first execution break in onload handler. If
onload one starts a long operation, it may take a lot of time before
the initial blank screen will be repainted by the actual content. I am
not saying that it is your problem but it is a very often problem for
many current script-intensive sites. In my solution I am always using
onload over overlay to release the context so to let the page to be
initially drawn:

<script type="text/javascript">

function init() {
// do your stuff
}

function releaseContextA ndInit() {
window.setTimeo ut('init()',10) ;
}

window.onload = releaseContextA ndInit;
</script>

P.S. That excludes situations when one indeed doesn't want to display
the page until all its content is fully prepared.

Firefox - replacing the whole page by the new one in Ajax response

by: evgenyg | last post by:

Hello ! We have the following situation - when Ajax request is sent what's being returned by the server is usually an XML (which is used for DOM updates) but sometimes it's HTML which is a whole new page that should replace an existing one.

ASP.NET AJAX: problems with UpdatePanel, GridView & RowCommand in Firefox

I have a user control which contains an UpdatePanel, which contains a MultiView inside, with a GridView in one of the views. In my GridView, I have a ButtonField which is supposed to trigger a server-side operation, using the RowCommand functionality. In IE, this all works great, but in Firefox (v2.0.0.6), clicking the above mentioned ButtonField fires off two similar AJAX requests, which is causing errors in my server-side code. ...
