Bootstrap 3 navbar链接不工作 [英] Bootstrap 3 navbar links not working
问题描述
我有一个导航栏，其中有链接。 品牌链接正在工作，但在 ul 中没有。我已经阅读关于 e.preventDefault（）; 是一个问题，当它与 $（'ul.nav> li'）的问题。我已经阅读了它与 z-index 有什么关系，我没有找到任何（除非我找不到嵌入在应用程序加载的 js 文件中，而不是驻留在我的资源文件夹中）。
I have a navbar with links in it. The "brand" link is working but nothing in the ul does. I have read things about e.preventDefault(); being a problem when it is with the $('ul.nav > li').click(function (e) {. I also have read where it has something to do with the z-index. I don't find any of those to be the case (unless I couldn't find it embedded in a js file loaded with the application and not residing in my assets folder).
这会导致什么原因？
我不确定是否会在 css 或 js 文件
此外，切换工作正常，只是活动链接。
I'm not sure whether it would be in the css or the js file.
Also, the toggle works fine, it's just the active links.

检查元素时发现错误...
TypeError：undefined不是一个指向 jquery.js c> file。
While inspecting elements, I found an error...
TypeError: undefined is not an object (evaluating '$(target).offset().top') which points to this part of the jquery.js file.
//smooth scroll
$('.navbar-nav > li').click(function(event) {
event.preventDefault();
var target = $(this).find('>a').prop('hash');
$('html, body').animate({
scrollTop: $(target).offset().top // this line here
}, 500);
});
但是，当我看一下jquery文档（ http://api.jquery.com/event.preventdefault/ ），它说，如果调用此方法，默认不会触发事件的操作。。
However, when I look at the jquery documentation (http://api.jquery.com/event.preventdefault/), it say, "If this method is called, the default action of the event will not be triggered.". So it seems that might be the case, but I'm not sure how to get around it.
推荐答案
我有很多同样的问题引起的Javascript。只需给一个链接一个ID和OnClick函数让你顺利地导航。
I had the very same problem caused by Javascript. Just give the a link an ID and the OnClick function lets you navigate smoothly.
HTML ：
<div class="navbar-collapse collapse " id="templatemo-nav-bar">
<ul class="nav navbar-nav navbar-right" style="margin-top: 40px;">
<li class="active"><a href="index.htm">HOME</a></li>
<li><a id="aboutus">ABOUT US</a></li>
<li><a id="clients">OUR CLIENTS</a></li>
<li><a id="products">PRODUCTS</a></li>
<li><a id="contact">CONTACT</a></li>
</ul>
</div><!--/.nav-collapse -->
JS：
document.getElementById("aboutus").onclick = function () {
location.href = "aboutus.html";
};
