Thank you guys. With your help now it's working. If anyone is interested here
is my final version (including code for confirmation):
var Confirm = Class.create();
Confirm.prototype =
{
initialize: function(element, message)
{
console.log("initialize -> " + element + " ---> " + message);
this.alreadyClickedOnce = false;
this.message = message;
var el = $(element);
var form = jQuery(el).closest("form");
Event.observe(el, 'click',
this.doConfirm.bindAsEventListener(this));
var self = this;
form.bind('submit',
function()
{
if (self.clickOnceTimeout != null)
{
window.clearTimeout(self.clickOnceTimeout);
}
});
},
doConfirm: function(e)
{
console.log("Clicked");
if (this.alreadyClickedOnce)
{
e.stop();
console.log("and cancelled");
return;
}
if(!confirm(this.message))
{
e.stop();
return;
}
console.log("Confirmed");
this.alreadyClickedOnce = true;
var self = this;
this.clickOnceTimeout = window.setTimeout(
function()
{
console.log("Let them click again")
self.alreadyClickedOnce = false;
},
3000);
}
};

Hi
You are using tapestry-jquery and trying to access a prototype library method.
Try bind instead of observe
