alter css values dynamically with javascript

Posted by chris on July 26th, 2007 Comments(0)

You can use javascripts document.getElementById().style method to alter CSS values. Here’s an example:

Create your div tag:

Now create your javascript function:

function changeCss()
{
     document.getElementById("myDiv").style.border = '2px dotted #CCC';
}

Now you can call this javascript function on any given event to alter your CSS tags border. Things like height, width, and a bunch others work as well. For instance create an html button, and onclick call the changeCss() function.

easy mysql backup

Posted by chris on July 6th, 2007 Comments(0)

Here’s an example of quick script I wrote in PHP and added as a cronjob to backup some mysql databases:

// dump database tables to sql text files //
exec('mysqldump -uroot -pPasswordHere music > /tmp/music.sql');
exec('mysqldump -uroot -pPasswordHere taskfreak > /tmp/taskfreak.sql');
// pack into tarballs //
exec("tar -cf /tmp/music.sql.tar /tmp/music.sql");
exec("tar -cf /tmp/taskfreak.sql.tar /tmp/taskfreak.sql");
// gzip tarballs //
exec("gzip /tmp/music.sql.tar");
exec("gzip /tmp/taskfreak.sql.tar");
