在jquery捕获后执行href

我不知道标题是否有意义，但代码值千言万语

以下是：

a href="http://twitter.com/intent/tweet?url=http://campaignmonitor.com/blog&text=I love the Campaign Monitor blog!&via=campaignmonitor&related=yarrcat" id="tweeter">Tweet it</a>

事实上，我喜欢在jquery函数中执行href。。。然后执行。。。可以是a href=“#”

问题，我如何对jquery函数说。。。。执行href

代码实际上相当于一个单词的1/78。

$('#tweeter').click(function(e){
     do some var loading
    and do some validation... 
    if validation fails then e.preventDefault() 
    else don't do anything as the browser will continue and redirect to the link 
});

     do some var loading
    and do some validation... 
    if validation fails then e.preventDefault() 
    else don't do anything as the browser will continue and redirect to the link 
});
