i would like to know about confirm and alert boxes

[Pat Gael]

Confirm and alert boxes are intended to show off a message on specific javascritpt events such as onLoad, onUnload, onClick, onMouseOver, etc.

Read more about javascript in the post you made elsewhere, where I pointed you at the available resouces, as for specific info about alerts here: www.pageresource.com/jscript/jalert.htm

Confirm boxes -------- usually called on existing a function call or a break from loop,condition and returns true or false depending on buttons pressed..
