如何使用php / jquery在窗口上显示叠加层

I have to disable website links all. if i place any overlay on website but it is not the right solution because we can remove that overlay using firebug or any browser tools...so is there any possible to freeze the site with out any actions...

Thanks, Murali

if you using jquery you can disable link action as follow

$(document).ready(function(e) {
    $('a').click(function(e){ 
        e.preventDefault();
    });
});

Basically e.preventDefault will intercept the default action
