Question

一直在努力解决这个问题，因为我是JS的新手。我想要实现的目标：

要对脚注进行多次引用（不能避免这种情况）。
能够引用回正确的ID

我的代码看起来像这样。

FIDDLE 的 HTML

<section>
    <p>Lorem<a id="fn1-ref" href="#fn1" title="link to footnote" class="art-fn-ref"><sup>1</sup></a>.</p>
    <p>ipsum<a id="fn2-ref" href="#fn2" title="link to footnote" class="art-fn-ref"><sup>2</sup></a></p>
    <p>dolor<a id="mulfn1-1-ref" href="#fn3" title="link to footnote" class="art-fn-ref"><sup>3</sup></a>.</p>
    <p>sit<a id="mulfn1-2-ref" href="#fn3" title="link to footnote" class="art-fn-ref"><sup>3</sup></a>.</p>
</section>
<aside>
    <ul>
        <li><a id="fn1" href="#fn1-ref" title="link to main text" class="art-fn"><sup>1</sup></a> Footnote 1</li>
        <li><a id="fn2" href="#fn2-ref" title="link to main text" class="art-fn"><sup>2</sup></a> Foonote 2</li>
        <li><a id="fn3" href="#mulfn1-1-ref" title="link to main text" class="art-fn"><sup>3</sup></a> Foonote 3</li>
    </ul>
</aside>

JS

//convention
//ID of reference to footnote= Caller ID
//ID of the footnote= FN ID
//HREF of the footnote that refer back to the caller ID = FN HREF

$(document).ready(function () {
    $(".art-fn-ref").one('click', function (e) {
        //001 - check if the Caller ID match a pattern (mulfn#)
        $('[id^=mulfn]').filter(function () {
            //002 - copy the 001 ID
            //003 - store the original HREF and ID of the footnote (FN HREF and FN ID)
            //004 - replace the FN HREF with HREF that points out to the correct caller ID
            //005 - once the "modified" FN HREF is clicked, restore it back to the original FN HREF
        });
    });
});

例如。脚注3有两个引用，其中包含以下ID＆＃34; mulfn1-1-ref＆＃34; ＆安培; ＆＃34; mulfn1-2-REF＆＃34 ;.假设我点击了＆＃34; mulfn1-2-ref＆＃34;它把我带到了＆＃34; fn3＆＃34;如果我点击fn3，我需要它带我回到＆＃34; mulfn1-2-ref＆＃34;而不是＆＃34; mulfn1-1-ref＆＃34;。

怎么做？请帮忙。

Answer 1

点击其中一个顶部链接

在链接到的脚注链接上添加data-href属性和引荐链接的ID
向脚注链接添加click事件侦听器，以禁用默认操作并将window.location设置为data-href值，然后删除事件侦听器

＆＃13;

$(document).ready(function () {
    $(".art-fn-ref").on('click', function (e) {
        var id = $(this).attr('id'),
        		$target = $($(this).attr('href'));
        $target.attr('data-href','#'+id);
        $target.on('click',function(e) {
        	e.preventDefault();
        	window.location = $(this).attr('data-href');
          $(this).off('click');
        })
    });
});
