有谁知道如何让JavaScript检索存储的超链接在页面上然后再使用它们？

Does anyone know how to get JavaScript to retrieve the hyperlinks that are stored on a page and then use them later on?

var anchors = document.getElementsByTagName（''a''）;

for（var i = 0; i< anchors。长度; ++ i）

{

alert（anchors [i] .getAttribute（''href''））;

}

var anchors = document.getElementsByTagName(''a'');
for (var i = 0; i < anchors.length; ++i)
{
alert(anchors[i].getAttribute(''href''));
}

如何在点击该链接时使用它来显示或操作链接？


例如如果用户点击了存储在数组中的链接，那么他/她将被重定向，如果没有，那么他们将转到指定的页面

http://www.thescripts.com/forum/thread700874.html ，这就是我目前正在使用的atm，它要求我添加以下所有href'的：


javascript ：validate（''someurl''）

and how could I use this to display or manipulate the link when that link has been clicked?

e.g. if the user has clicked upon a link which was stored in an array then he/she would be redirected and if not then they would go to the specified page

http://www.thescripts.com/forum/thread700874.html, this is what I am currently using atm which requires me to add the following to all href''s:

javascript:validate(''someurl'')

添加使用onclick而不是href的validate函数，即当你遍历链接时，添加一个onclick，它将this.href传递给validate函数。

Add the validate function using onclick rather than as a href, i.e. when you loop over the links, add an onclick which passes this.href to the validate function.
