HTML anchor tags not working in Firefox, Safari, i

问题:

My html anchor tags work in chrome and IE but in Firefox, Safari, iPad and iPhone they do not work, how come? and what can I do to fix it?

<a href="/services#underpinning">Underpinning</a>

Any help would be appreciated.

Thanks.

This is what I am trying to link it to on the services page:

<h1 id="#underpinning" name="underpinning">Underpinning</h1>

This is where I left off:

This is my link:

<li><a href="/services#underpinning"><h2 id="underpinning">Underpinning<a href="services#underpinning"><img class="alignnone size-full wp-image-127" alt="home" src="http://powellgroupconstruction.com/wp-content/uploads/2013/12/home.jpg" width="500" height="337"></a></h2></a></li>

This is where on my services page I want the link to goto:

<a name="underpinning"><h1 id="underpinning" name="underpinning">Underpinning</h1></a>

If I goto the url directly: http://powellgroupconstruction.com/services/#underpinning into safari or firefox, it works.

There are several issues in your code. On your example website you're using HTML5 Doctype, so I'm just answering respectively with HTML5 in mind:

1. Forget about name attribute in general and <a name> markup as link target in particular.
   
   As the HTML5 Candidate Recommendation spec states:
   "An element's unique identifier can be used for a variety of purposes, most notably as a way to link to specific parts of a document using fragment identifiers, as a way to target an element when scripting, and as a way to style a specific element from CSS."
   That means, you can use any id as a link target.
   
   
2. As Itay Gal has already stated in his answer, don't use the same id more than once. From the HTML5 spec again:
   "The id attribute specifies its element's unique identifier (ID)".
   That said, change your current code:
   <a id="underpinning" name="underpinning"><h1 id="underpinning" name="underpinning">Underpinning</h1></a>
   to
   <h1 id="underpinning">Underpinning</h1>
   
   
3. You're using as link address currently /services#underpinning. As you're going with the WordPress rewrite functionality, entering http://powellgroupconstruction.com/services gets redirected to http://powellgroupconstruction.com/services/.
   Therefore you should better put a slash at the end of your pages' names, so the link address should be
   <a href="/services/#underpinning">Underpinning</a>

You are using the same id in multiple elements. The id needs to be unique, make sure you use each id only once and it should work.

回答3:

Are href for both h2 and img tags are same? then have you tried this one:

    <a href="services#underpinning">
<h2 id="underpinning">Underpinning

<a href="services#underpinning"><img class="alignnone size-full wp-image-127"      alt="home" src="http://powellgroupconstruction.com/wp-content/uploads/2013/12/home.jpg"  width="500" height="337">
</a></h2>

    </a>

I had an issue very similar to this. I believe your problem is that Firefox and Safari do not like an <h2> tag inside an anchor <a> tag. Try :

<a href="/services#underpinning"><span id="underpinning">Underpinning</span></a>
