滚动到部分导航问题

Question

我正在构建单页网站，需要'滚动到部分导航'，我将此jsfiddle用作基本模板。正如你可以看到它就像一个魅力，但在我的网站上的一些原因，它似乎并没有工作，我已经粘贴下面

<!-- THIS IS A SECTION --> 

<section id="about" data-anchor="about"> 
    <div id="about-wrap"> 
    <h1>I'm a really cool title about<br>Small Space Living</h1> 
    <p>Lorem ipsum dolor sit amet, consectetur ...esse.</p> 
    <a class="link" href=""><span>Learn More</span></a> 
    </div> 
</section> 


<!-- THIS IS MY NAVIGATION --> 

<div class="navbar pull-right"> 
    <ul class="navi"> 
    <li><a href="#" data-scroll="about">About Us<hr></a></li> 
    <li><a href="#" data-scroll="solutions">Solutions<hr></a></li> 
    <li><a href="#" data-scroll="contact">Contact Us<hr></a></li> 
    </ul> 
</div> 


<!-- THIS IS MY JQUERY --> 

<script> 
$(document).ready(function(){ 
$(function(){ 
$('navi a').on('click', function() { 

    var scrollAnchor = $(this).attr('data-scroll'), 
     scrollPoint = $('section[data-anchor="'+scrollAnchor+'"]').offset().top -10; 

    $('body,html').animate({ 
     scrollTop: scrollPoint 
    }, 500); 

    return false; 

}) 

$(window).scroll(function() { 

}); 

$(window).scroll(function() { 

    if ($(window).scrollTop() >= 100) { 

     $('nav').addClass('fixed'); 

    } else { 

     $('navi').removeClass('fixed'); 

    } 

}); 
});//]]> 
}); 
</script> 

了几个重要的代码片段有CSS相当数量，但我无法想象这是一个风格问题，因为jsfiddle没有风格，仍然有效。

任何帮助真的不胜感激。提前致谢！

我创建了其中的以下文件：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"> 
</script> 

<script> 
window.onload = function() { 

$('nav a').on('click', function() { 

    var scrollAnchor = $(this).attr('data-scroll'), 
     scrollPoint = $('section[data-anchor="'+scrollAnchor+'"]').offset().top -10; 

    $('body,html').animate({ 
     scrollTop: scrollPoint 
    }, 500); 

    return false; 

}) 

$(window).scroll(function() { 

    if ($(window).scrollTop() >= 100) { 

     $('nav').addClass('fixed'); 

    } else { 

     $('navi').removeClass('fixed'); 

    } 
}); 

} 
</script> 
<header></header> 

<nav> 

    <a href="#" data-scroll="top">TOP</a> 

    <a href="#" data-scroll="news">NEWS</a> 

    <a href="#" data-scroll="products">PRODUCTS</a> 

    <a href="#" data-scroll="contact">CONTACT</a> 

</nav>

    </section> 

然后我将它保存为index.html。打开它，它工作。

您遇到的主要问题是$('navi a')，我将其更改为'$（'nav a'）`。我认为一个小小的错字会让你失望。

编辑 我觉得我应该解释更好一点。您不应使用.navi，因为它指的是对象的类别：。您不应该使用#navi，因为它指的是对象的ID：。使用navi引用一个对象。既然你想引用一个标签，我们使用$('nav')。希望这个澄清一点。

它在那里很好用。是否有可能阻止此脚本的其他js错误？

@EDIT：试试这段代码：你错过了班级定义中的一个点！ $('.navi a')。

$(document).ready(function(){ 
$('.navi a').on('click', function() { 

var scrollAnchor = $(this).attr('data-scroll'), 
    scrollPoint = $('section[data-anchor="'+scrollAnchor+'"]').offset().top -10; 

$('body,html').animate({ 
    scrollTop: scrollPoint 
}, 500); 

return false; 

}); 
}); 

如果你不希望任何动画，你可以使用这个简单的锚有：

<nav> 

<a href="#top">TOP</a> 

<a href="#news">NEWS</a> 

<a href="#products">PRODUCTS</a> 

<a href="#contact">CONTACT</a> 

</nav>
