You can’t set the float propety directly, like other properties, e.g. element.style.fontSize= "small";

One needs to use cssFloat for standard-compliant browsers, and styleFloat for Internet Explorer.

Simply set both of them. It will not cause any problems, and will work in all possible browsers.

    element.style.cssFloat = "right";
    element.style.styleFloat = "right";

Here is a function that returns the current date in JavaScript in the following format : May 29, 2007

function getCurrentDate(){
        var months = new Array(’January’,'February’,'March’,'April’,'May’,
            ‘June’,'July’,'August’,'September’,'October’,'November’,'December’);
        var date = new Date();
        var month = date.getMonth();
        return months[month] + " "+ date.getDate() +" , "+ date.getFullYear();
 }

I wrote a tutorial that shows how to build two select boxes in JavaScript where values in the one depend on the value in the other.

  [-a-z\d]   -  a character class that matches a hyphen, letter, or digit

Some metacharacters:  

 Quantifiers:

    *      Match 0 or more times
    +      Match 1 or more times
    ?      Match 1 or 0 times
    {n}    Match exactly n times
    {n,}   Match at least n times
    {n,m}  Match at least n but not more than m times

To enable url rewriting on a per-directory basis, you need to use an .htaccess file that should be located in the directory used for url
rewriting.

In the .htaccess file, type: 

Options FollowSymLinks
RewriteEngine On

Then use the RewriteRule directive, e.g:

RewriteRule ^oldname.php$ /subsite/newname.php [R] 

A very basic mod_rewrite tutorial is located at http://www.webmastertips.us/tutorials/mod_rewrite.htm 

 However, there is an important detail missing from the tutorial - make sure the <Directory…> container in the httpd.conf file contains the following directive:

 AllowOverride All

If AllowOverride is set to None, no url rewriting will take place. 

Also, do not forget to uncomment the LoadModule rewrite_module modules/mod_rewrite.so directive in the httpd.conf file.

For creating .htaccess, don’t create it inside Explorer. Open Notepad, type something and SAVE AS “.htaccess” and choose the file type as “ALL FILES”.

To get session values in JSTL, use the following piece of code:

<c:forEach items="${sessionScope}" var="par">
        Session object name/value : <c:out value="${par.key} - ${par.value}"/>
</c:forEach>

I always have trouble remembering the correct arguments to the substring() method in order to delete the last character in a String.

Here is how you do it in Java: 

str =  str.substring(0, str.length()-1);

A similar statement in PHP:

$str = substr($str,0, strlen($str)-1);

Apparently, you cannot continue a long string on multiple lines with a \ separator like you do it in C or JavaScript.

Can’t be done. Gotta use the plus sign or append() to a StringBuffer. So the post title is actually misleading.
