Disable your site from Greasemonkey !!!

I've found this by an accident!!!

 document._createElement = document.createElement;
 document.createElement = function(tagName, password) {
    if (tagName != "SCRIPT" || password == "My scripts are OK!") {
        return document._createElement(tagName);
just that and your site will be protected

javascript to show and hide element

for html you need to define ID name of an element

<input type="button" name="clickme1" id="clickme1" value="Click me !!" onclick="JavaScript:showbutton('clickme2')"><BR>
<input type="button" name="clickme2" id="clickme2" value="Click me !!" onclick="JavaScript:showbutton('clickme1')" style="visibility:hidden">
For javascript need this code
function showbutton(idName){
 Element = document.getElementById('clickme2');
 Element.disabled=true; = "hidden";
 Element = document.getElementById('clickme1');
 Element.disabled=true; = "hidden";
 clickme1Element = document.getElementById(idName);
 clickme1Element.disabled=false; = "visible";
