我在引导程序中遇到了菜单 div 的问题。

我有一个带有四个链接的顶部菜单，这些链接指向我网站的相应部分。链接被 jquery 脚本“劫持”，因此它们会将页面滚动到该部分。我想要的是放置一个指向外部链接的链接，但是当我放置<a href标签时它什么也不做。

我的代码

            <ul class="unstyled inline pull-right top-menu">
             <li><a href="http://myblog.tumblr.com">Blog</a></li>
              <li><a href="#contact">contact</a></li>        
              <li><a href="#newsletter">Newsletter</a></li>                
            </ul>

任何想法我将如何绕过仅针对我的外部链接的 scrollTo 功能，但将其包含在我的菜单 div 中？

我从未使用过 scrollTo 插件，但使用引导程序我使用以下内容进行动画滚动。因为我只针对以#我所有其他链接开头的链接按预期工作。 

$(document).ready(function(){
    if(window.location.hash) { //If page loads with hash
        scrollToID(window.location.hash);
    }
    $('a[href^="#"]').click(function(event){ //Only target links that start with #
       event.preventDefault();
       scrollToID($(this).attr('href'));
    });
});     

function scrollToID(ID){
    var navOffset = ($(window).width() > 979) ? 93 : 0; //adjust this if you have a fixed header with responsive design
    $('html, body').animate({
        'scrollTop': $(ID).offset().top - navOffset
    }, 'slow');
}
