about checkbox

i am designing a page that contains a checkbox,
if the checkbox is checked, then it will show another column(the checkbox is placed under a table).... however, i don't really know how i can achieve this.....

here is my code:
<form name="form2" method="post" action="">
<input type="checkbox" name="checkbox" value="checkbox" onClick="???">
<font size="1">Display Photo(s) </font>


can anyone suggests me someone way to solve this, thanks

i do not know much but u can use innertext property of the JAVASCRIPT to do this.U can get help on innertext property on the web.Sorry i am in a hurry.If i am able to fine the code i will put it here.Bye everyone.......

Here's how I'd do it:



Or course you'd have to put your column content in the string being written by "document.write". I just put a bank row in there to show you how it would look, and so that you would know you can put HTML tags in the string.

Since you're new I'm not sure how much javascript you know. So, it may be vital to add...that this code would need to go b/t the head tags in script tags like this




Then in the body of the page wherever you want you check box...

Is the hidden column already there in the code but you just want to show/hide it when the checkbox is clicked?

Example

i have already got a table, but i would like to create an EXTRA column that i can control its appearance

Well, the dom-2 spedification allows you to create new nodes, but it's somewhat complicated and requires a bit of practice. I just started looking at it recently myself, and here's what I came up with for adding a column to a table using dom-2 methods.

example

I was also able to do pretty much the same thing with innerHTML by using a pre-existing column that was empty and changing it's contents. This is a lot simpler but lacks the flexibility of creating and removing individual nodes on the fly.
