Can a Button be Made Invisible Via Javascript

[clyde]

I have several butons in my HTML, Depending on conditions
can I make buttons visible or invisible via Java Script

[Khalid Ali]

yes..you can use CSS properties such as
visibility and display

suppose you had an input element of type button name="btn"
in a form name="form1"

following will make it disappear

document.form1.btn.style.visibility="hidden";

and following will make it re appear

document.form1.btn.style.visibility="visible";
