Ajax

**evans123** · 10-31-2009, 06:17 AM

Can anyone help me or tell me how to send an ajax request upon a live time change for example

15:15 - Load Content
15:16 - Load Content
15:17 - Load Content

ect...

Is this possible?

It is but you would probably crash the browsers after a few iterations.

A JAVA applet would be a better method, with that you could update every few seconds without draining resources.

do you think it would crash if i used window.SetInterval(functio, time); I only need it to load a string of text etc.

It's not what you load but how! Each iteration will which take up a bit of memory, try leaving Gmail (AJAX version) open for a while and see how the memory usage goes up.

Also IE locks the XMLhttp object so you have to do a bit of hoop jumping to make it fully cross browser functional, even ver8 seemingly, when I tested it a few months ago. (I use AJAX in a application backend that needs to make several server calls)

would this work

Code:

//Submit Data
function submitData(pageId, data, type) {
type = typeof(type) != 'undefined' ? type : 'GET';
//passedData = typeof(passedData) != 'undefined' ? passedData : '';
$(document).ready(function()
{
    message();
    $.ajax({
    type: type,
    data: data+'&pageId='+pageId,
    url: 'ajax/includes/content.php',
    cache: false,
    success: function(data){
     $('#content_holder').html(data);
     remove_message();
    }
    });
});
return false;
}

Run this on a timer???

haven't a clue.

I assume you are using some kind of "framework"?

**evans123** · 10-31-2009, 08:56 AM

yup, jquery!

Ok! I don't use any of them so I have no idea of the syntax.
