So has anybody else around here used AJAX for anything? AJAX is basically using Javascript to send/retrieve information from the server. I've recently started trying to encorperate it into a project I have been working on and so far have found it to be fairly easy to use and it should be pretty useful. I'd be very interested in seeing someone elses work with AJAX though as mine has been bit of a case of making it up as I go along  |

No, but I have looked at it. It seems interesting, but I think Ill stick with PHP right now. I never did really like how Javascript goes. I mean the syntax. It just seems wierd.

I actually used AJAX recently; It was for Enchant's Website..she didn't want to use Iframes.
function getPage(url, objId) {
var call_page = (window.XMLHttpRequest)? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP");
call_page.onreadystatechange = function() {
loadpage(call_page, objId);
}
call_page.open('get', url, true);
call_page.send(null);
}
function loadpage(call_page, objId){
if (call_page.readyState == 4 && (call_page.status == 200 || window.location.href.indexOf("http")==-1)){
document.getElementById(objId).innerHTML = call_page.responseText;
}
}
nothing fancy, but quite affective  |

Amused To Death, what the code Dre posted does is grabs the contents of another file (the file will depend on what link is clicked) and writes its contents to part of the page. And all that without the page having to be refreshed. Dre, looks good. With the one I'm doing, I'm looking at the possibilities of using the XML version to check if the code has returned certain information and then dealing with each piece returned seperately. For me, the biggest challenge has been handling javascript functions that need to be loaded and called after the AJAX request has been sent. You see, I'm using AJAX to submit a form and then depending which form is submitted, I want to load an external JS file which changes some of the text/links on the page, I just don't want this external js file to be sent to the page every time. I'm just wondering though, maybe it'd be easier if I grabbed the file contents as text and just wrote out the JS, not sure if that'd work though  |

So Ross, what you want to do is when request is sent you want to write specific JS on to the web page? why not setup a function that when a form submit button is pressed it writes a specific JS file using a function. If you want those text/links to be more persistent, why not use cookies? and it reads the cookie and writes that JS file.
I'm not 100% sure what you want done, maybe a little more detail ? >.<

nice code, Dre. I haven't learnt AJAX. I'm still learning HTML and javascript. Beginning languages come first |

The AJAX request returns the URL to an external JS file (if necessary) which the code already on the page uses to create a new script element, append it to the <head> element and then call the function within. Not perfect, but it seems to be working well enough for my purposes |

Wouldnt AJAX be somewhat similar to PHP because it deals with servers(etc)? |
