平滑滚动末端定位

发布于 2024-12-27 15:19:23 字数 1913 浏览 1 评论 0原文

我有一个漂亮的平滑动画滚动,根据您在导航上单击的内容上下移动(感谢 CSS 技巧!)。现在这一切都工作得很好,但我有一个导航贴在浏览器窗口的顶部,并在向下滚动时妨碍部分标题。我一生都找不到任何人可能对一个看起来非常简单的函数有类似的问题。

这是我粘贴到 HTML 中的 JS:

<script type="text/javascript">
$(document).ready(function() {
  function filterPath(string) {
  return string
    .replace(/^\//,'')
    .replace(/(index|default).[a-zA-Z]{3,4}$/,'')
    .replace(/\/$/,'');
  }
  var locationPath = filterPath(location.pathname);
  var scrollElem = scrollableElement('html', 'body');

   $('a[href*=#]').each(function() {
    var thisPath = filterPath(this.pathname) || locationPath;
    if (  locationPath == thisPath
    && (location.hostname == this.hostname || !this.hostname)
    && this.hash.replace(/#/,'') ) {
      var $target = $(this.hash), target = this.hash;
      if (target) {
        var targetOffset = $target.offset().top;
        $(this).click(function(event) {
          event.preventDefault();
          $(scrollElem).animate({scrollTop: targetOffset}, 800, function() {
            location.hash = target;
          });
        });
      }
    }
  });

  // use the first element that is "scrollable"
  function scrollableElement(els) {
    for (var i = 0, argLength = arguments.length; i <argLength; i++) {
      var el = arguments[i],
          $scrollElement = $(el);
      if ($scrollElement.scrollTop()> 0) {
         return el;
      } else {
        $scrollElement.scrollTop(1);
        var isScrollable = $scrollElement.scrollTop()> 0;
        $scrollElement.scrollTop(0);
        if (isScrollable) {
          return el;
        }
      }
    }
    return [];
  }

});</script>

我正在学习 JS 和 JQuery,所以我感谢大家的耐心,并期待听到您的评论。

非常感谢。

编辑:这是我的测试站点:测试

I have a nifty smooth animated scroll that goes up and down depending on what you click on the navigation (thanks to CSS-Tricks!). Now this is all working great but I have a nav that sticks to the top of the browser window and gets in the way of the section headers when it scrolls down. I can't for the life of me find anyone who may have had a similar issue with, what seems like, a very simple function.

Here's the JS that I have pasted into my HTML:

<script type="text/javascript">
$(document).ready(function() {
  function filterPath(string) {
  return string
    .replace(/^\//,'')
    .replace(/(index|default).[a-zA-Z]{3,4}$/,'')
    .replace(/\/$/,'');
  }
  var locationPath = filterPath(location.pathname);
  var scrollElem = scrollableElement('html', 'body');

   $('a[href*=#]').each(function() {
    var thisPath = filterPath(this.pathname) || locationPath;
    if (  locationPath == thisPath
    && (location.hostname == this.hostname || !this.hostname)
    && this.hash.replace(/#/,'') ) {
      var $target = $(this.hash), target = this.hash;
      if (target) {
        var targetOffset = $target.offset().top;
        $(this).click(function(event) {
          event.preventDefault();
          $(scrollElem).animate({scrollTop: targetOffset}, 800, function() {
            location.hash = target;
          });
        });
      }
    }
  });

  // use the first element that is "scrollable"
  function scrollableElement(els) {
    for (var i = 0, argLength = arguments.length; i <argLength; i++) {
      var el = arguments[i],
          $scrollElement = $(el);
      if ($scrollElement.scrollTop()> 0) {
         return el;
      } else {
        $scrollElement.scrollTop(1);
        var isScrollable = $scrollElement.scrollTop()> 0;
        $scrollElement.scrollTop(0);
        if (isScrollable) {
          return el;
        }
      }
    }
    return [];
  }

});</script>

So I am in the process of learning JS and JQuery so I appreciate everyones patience and look forward to hearing your comments.

Many thanks in advance.

获取 jquery.scrollTo.js 的副本
来自 http://flesler.blogspot.com/2008/09/jqueryscrollto- 14-released.html

这是控制滚动项的位置的

 $.scrollTo( 0, 500); 

,如果您设置更高的数字,0 将到达页面顶部
它会占据页面下方,在我的示例中,我有 5 个部分想要滚动到。根据需要进行更改。

我在头部部分使用了这个:

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script>


 <script type="text/javascript" src="javascripts/jquery.scrollTo.js"></script>
 <script type="text/javascript">
 $(document).ready(function()
 {
 // scroll to top
 $('a.topOfPage').click(function(){
 $.scrollTo( 0, 500);
 return false;
 });
 // scroll to top
 $('a.twoOfPage').click(function(){
 $.scrollTo( 570, 500);
 return false;
 });
 // scroll to top
 $('a.threeOfPage').click(function(){
 $.scrollTo( 1175, 500);
 return false;
 });
 // scroll to top
 $('a.fourOfPage').click(function(){
 $.scrollTo( 1790, 500);
 return false;
 });
 // scroll to top
 $('a.fiveOfPage').click(function(){
 $.scrollTo( 2385, 500);
 return false;
 });
 });
 </script>

在主体部分相应的导航中:

 <ul class="pagination">

   <li><a href="" class="topOfPage">1</a></li>
   <li><a href="" class="twoOfPage">2</a></li>
   <li><a href="" class="threeOfPage">3</a></li>
   <li><a href="" class="fourOfPage">4</a></li>
   <li><a href="" class="fiveOfPage">5</a></li>

 </ul>  

如果您需要更多参考,我通过找到了原始代码
http://nick.boldison.com/ websites/jquery/jquery-scroll-to-top-animation-scrollto-plugin/

我希望对您有帮助。

干杯

Get a copy of jquery.scrollTo.js
from http://flesler.blogspot.com/2008/09/jqueryscrollto-14-released.html

This is what controls the position of the scroll item

 $.scrollTo( 0, 500); 

the 0 would take to top of the page, if you set higher figure
it would take your lower down the page, in my example I have 5 sections I wanted to scroll to. Change as you need.

I used this in the head section:

 <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script>


 <script type="text/javascript" src="javascripts/jquery.scrollTo.js"></script>
 <script type="text/javascript">
 $(document).ready(function()
 {
 // scroll to top
 $('a.topOfPage').click(function(){
 $.scrollTo( 0, 500);
 return false;
 });
 // scroll to top
 $('a.twoOfPage').click(function(){
 $.scrollTo( 570, 500);
 return false;
 });
 // scroll to top
 $('a.threeOfPage').click(function(){
 $.scrollTo( 1175, 500);
 return false;
 });
 // scroll to top
 $('a.fourOfPage').click(function(){
 $.scrollTo( 1790, 500);
 return false;
 });
 // scroll to top
 $('a.fiveOfPage').click(function(){
 $.scrollTo( 2385, 500);
 return false;
 });
 });
 </script>

In the body section corresponding nav:

 <ul class="pagination">

   <li><a href="" class="topOfPage">1</a></li>
   <li><a href="" class="twoOfPage">2</a></li>
   <li><a href="" class="threeOfPage">3</a></li>
   <li><a href="" class="fourOfPage">4</a></li>
   <li><a href="" class="fiveOfPage">5</a></li>

 </ul>  

If you need more ref I found the original code via
http://nick.boldison.com/websites/jquery/jquery-scroll-to-top-animation-scrollto-plugin/

I hope that helps you.

Cheers
