My intention was to show how to use table for drawing (attach onmouseover event handler to table cells and to change selected color when mouse pointer is over cell). On the other hand, now in HTML5 era, drawing in browsers is much easier using canvas element and canvas element has ready method to save drawn images - <strong>toDataURL()</strong>.

The same is with sending it in e-mail. ;) @Lenny - Drawn image is actually HTML, so I suppose that saving innerHTML of TABLE node should not be a problem. The same is with sending it in e-mail. ;)

It’s a very nice script, by the way. Thanks. Dbunic,

But I'm looking for something that is more efficient than this. I'm looking for the help about drawing charts and graphs in the browser from the data in the database. It's indeed a very good post...!

And as you said, you can simply put this few JavaScript lines to the HTML page. Just click to the "view plain" and copy source code to your file. Please, don't forget to create DIV tag with id="drawing_table" where <em>create_table()</em> function should generate HTML table tags. If you open HTML source of this post, search for the keyword "drawing_table" and you will see styles and needed HTML code. Simon,

Do you call it from a PHP script or do you simply put this code in an HTML/PHP script? I am trying to create something close to a whiteboard, but I am not having any luck in coding it; so some response will be appreciated.
