Answer 1

Yeah, see here for an example. It uses getComputedStyle to find out if a link has been visited. There's also a variant of this hack that doesn't require scripting .

The relevant part of the example is this (modified for clarity):

a:visited {
    color: #00f;
}

var link = document.createElement('a');
link.href = 'http://example.com/';
document.body.appendChild(link);
var color = document.defaultView.getComputedStyle(link, null).getPropertyValue('color');       
// check for visited
if (color == "rgb(0, 0, 255)") {           
    alert(link.href + ' has been visited');
}

May I ask what do you need it for?

Edit: WRT #2, you could open the link in an iframe . That would mark it as visited in the browser history. Like so:

var iframe = document.createElement('iframe');
iframe.src = 'http://example.com/';
document.body.appendChild(iframe);

Edit : You can create new CSS rules with JS. There's a jQuery plugin to make it more simple. Basically, you would do it like this:

$.rule('a:visited { color: #f06 !important }').appendTo('style');

通过CSS怎么做？

a:visited {display:none;}
