The named anchor at the bottom of the page doesn't work more than once on an iPhone. Any suggestions? Thanks, Andy.

如果锚点没有改变，iPhone 似乎就不会滚动，当然，当你第二次点击链接时，iPhone 就不会滚动。这可能是由于 iPhone 上滚动的工作方式（移动视口）造成的，

我想一种解决方案是使用一些 javascript 来在每次单击“返回顶部”链接时替换其目标，例如在“#top”之间'和'#top2'。

编辑

所以我认为类似 jquery 的东西可以解决这个问题。在 html 中，您只需创建大量指向 #top 的链接，

jquery 将这些链接替换为 topXa，其中 X 从 0 开始计数。然后我们附加一个单击处理程序，该处理程序在每次单击时将 a 替换为 b。这应该使每次点击都是独一无二的。在<之前添加eg /身体>

<script type="text/javascript"
 src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
  $(document).ready(function() {

      switch_top = function(e) {
      var link = $(e.target);
      var href = link.attr('href');
      if(href.search('a') != -1)
          href = href.replace('a','b');
      else
          href = href.replace('b','a');

      link.attr('href',href);
      };

      var counter = 0;
      $('a[href="#top"]').each( function(index, value) {
      link = $(value);
      link.
          attr('href', '#top' + (counter++) + 'a')
          .click( switch_top);
      });

  });
</script>

it seems the iphone doesn't scroll if the anchor doesn't change, which of course it doesn't the second time you click the link. this may be due to the way scrolling works on the iphone (moving the viewport)

i guess one solution would be to use some javascript to alternate the target of your 'back to top' link each time it is clicked, e.g. between '#top' and '#top2'.

EDIT

So i think something like this piece of jquery would do the trick. in the html you just make a load of links that point to #top

the jquery replaces these by topXa where X counts up from 0. we then attach a click handler which swaps the a's for b's on each click. that should make each click unique. add e.g. just before < /body >

<script type="text/javascript"
 src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
  $(document).ready(function() {

      switch_top = function(e) {
      var link = $(e.target);
      var href = link.attr('href');
      if(href.search('a') != -1)
          href = href.replace('a','b');
      else
          href = href.replace('b','a');

      link.attr('href',href);
      };

      var counter = 0;
      $('a[href="#top"]').each( function(index, value) {
      link = $(value);
      link.
          attr('href', '#top' + (counter++) + 'a')
          .click( switch_top);
      });

  });
</script>
