The history object

When you are surfing the net, you often use the back and forward buttons to go back to a page you have already visited. The history object allows us to travel forwards and backwards in script.

The use of the history object is straightforward.

history.back();

sends us back one page

history.forward();

sends us forward one page

We can also use

history.go(n);

which sends us forward n pages (n>0), or back n pages (n<0).

history.length retrieves the number of elements in the History list.

如果我在一个会话结束时，我想把在这期间访问过的历史记录都去掉该怎么办？

[saucer]

method 1: use location.replace to load all the pages in 一个会话

method 2: close the window and open a new one

给你个例子吧，
<input type=submit name="press" value="数据错误请返回" onclick="javascript:history.back()" >

[wjmmml]

你把history.back（）换成上面兄弟说的你想用的属性就可以了。

[redv]

window.history.back()
window.history.forward()
window.history.go()
window.history.length

eg:
window.history.go(-1)==window.history.back()
window.history.go(1)==window.history.forward()
window.history.go(-2)

histroy.length: readonly

If you are interested in it, you will find some fun in testing this:

JavaScript:{var str=window.location;histroy.go(-history.length);window.location.replace(str);}

you can also change str to something else;
