Select All and De-select All

Implementing using javascript

[Ljm32]

I have a web page containing a dynamic table where each row can be selected. I want to add a Select All and De-select All button which is actually an anchor with an image. Could someone let me know how to call/create a javascript function to acheive this.

Thanks.

When you say

each row can be selected

do you mean each row has a checkbox on it?
