Let me just say, when you are writing a new web application, Ajaxify it!
Ajax takes your web app to the next level. The ability to access server side scripts and databases without having to reload the web page makes it absolutly amazing.
If you are unfamiliar or new to the concept then allow me to explain the basics. Ajax is not a new technology or programming language but rather a group of web languages that work together. While the official acronym stands for Asyncronous JavaScript and XML technology, the real explaination is the ability for client side JavaScript to access/run server side scripts like PHP and then apply the output of that server side script to the current web page without reloading the page or submiting a form.
So what are you waiting for? Here are some great places to get started:

If you just switched office computers and you’re wondering why the TO box in Outlook doesn’t autocomplete your co-workers email address like your old computer did then what you have encountered is a missing Outlook.NK2 file. The Outlook.NK2 file is a cached list of all email addresses that you have sent to for future autocomplete use.
If you still have the old computer then you can simply copy offer that nk2 file to the new machine. Here is the file path:
C:\Documents and Settings\user\Application Data\Microsoft\Outlook\Outlook.NK2
The filename may also be the name of the user account but still has the .NK2 file extension.
These files may also become corrupted (like anything microsoft). If that is the case then you can try to recover the data with a utility like NK2View.

I would just like to preface this article by saying IE sucks. Seriously… standards have been made, all browsers comply EXCEPT Microsoft Internet Explorer. Microsoft = marketing not quality.
I have just recently tried to dynamically generate an option element list for a select element via an AJAX call. This works great in FF and Chrome, but IE7 is just a giant fail. After some research and viewing several solutions, here is mine… straight forward and simple.
HTML:
<span id=”elementid”></span>
JavaScript:
document.getElementById(“elementid”).innerHTML=xmlhttp.responseText;
Server Side Script (PHP):
$result = mysql_query($sql,$dblink);
echo “<select name=’item’>”;
while($row = mysql_fetch_assoc($result)) {
echo “<option value=’{$row['ID']}’>{$row['ItemName']}</option>”;
}
echo “</select>”;
I ended up generating the select elements and the option elements within the JavaScript because IE would not allow me to use innerHTML to place option elements within the select element.
IE = fail
