锚定到隐藏 div 中的元素答案

【问题标题】：Anchor to element within hidden div锚定到隐藏 div 中的元素
【发布时间】：2017-02-21 12:59:51
【问题描述】：

我正在尝试在另一个页面上创建一个指向锚点的 href 链接（我们将其称为第 2 页以使其更容易），但是在第 2 页上，有问题的锚点包含在一个 div 中，当你首先访问它（当单击标题时，div 会展开以显示内容。所以当然默认情况下，div 具有属性'display:none'）。

这是我所说的确切类型的一个小样本。

<html>

<head>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<style>
p {color:#000;}
</style>

<script>
$(document).ready(function(){
    $("#f-hdr").click(function(){
        $("#hidden").toggle(1000);
    });
});
</script>

</head>




<body>

<a href="#anch">Link to anchor within hidden div</a>

<h2><a id="f-hdr" href="javascript:void(0)">Div Header</a></h2>

<div id="hidden" style="display:none">

<p id="anch">some text</p>

</div>

</body>
</html>

谢谢！

编辑 - 例如，如果我在“第 1 页”上，我希望能够打开指向“第 2 页”上特定元素的链接（在本例中为 #anch）但“#anch”是包含在第一次打开页面时隐藏的 div (#hidden) 中。最初，要访问“#hidden”中的内容，用户必须单击标题，这会展开 div 以显示内容。我希望能够单击指向“#anch”的链接（这会将我带到“第 2 页”）并查看“#anch”中的内容，而无需先单击标题。

据我所见，这可能与“onhashchange”事件有关。虽然我不太确定（因此发帖）:)

标签： javascript jquery html anchor hidden

【解决方案1】：

有两种方法可以使用 W3schools 建议的名称锚属性来完成这一任务。

W3schools：https://www.w3schools.com/tags/att_a_name.asp

另一种方法可能是使用行为类似于名称锚点的通用 jquery 方法。

HTML：

<a class="nameLink" href="#hidden" >Link to anchor within hidden div</a>

<h2><a id="f-hdr" href="javascript:void(0)">Div Header</a></h2>
<p class="dummy-height"></p>
<div id="hidden" >
  <p id="anch">some text</p>
</div>

jQuery：

$(document).ready(function(){
    $("#f-hdr").click(function(){
        $("#hidden").toggle(1000);
    });
    $(".nameLink").on('click', function(){
                $($(this).attr('href')).show(); 
    })
});

注意：这里的 nameLink 是可以分配给任何锚链接以使用相同功能的类。

最后是链接：

希望这能解决您的问题。

更温暖，但不幸的是没有（抱歉！开始后悔我在问题中选择的词语，哈哈）我已经将小提琴修改为更接近我正在研究的东西 - @987654323 @我希望能够单击该链接并将其链接到“我正在寻找的人”我知道这是不可能的，而包含的 div 具有属性“显示：无”。我需要链接跳转到“我正在寻找的人”，而无需先手动扩展 div（如果这有任何意义） - 谢谢您的帮助。
我已经更新了代码和链接。请检查。希望这可以帮助！ :) 链接：jsfiddle.net/Ashokkumargupta/bc1drx0s

【解决方案2】：

解决方法是你需要使用visibility: hidden而不是display: none。

我的意思是你需要改变这个：

<div id="hidden" style="display:none">
   <p id="anch">some text</p>
</div>

通过这个：

<div id="hidden" style="visibility: hidden">
   <p id="anch">some text</p>
</div>

更多信息你可以查看这个问题What is the difference between visibility:hidden and display:none?

display:none 意味着有问题的标签根本不会出现在页面上（尽管您仍然可以通过 dom 与它进行交互）。其他标签之间不会为它分配空间。

visibility:hidden 表示与 display:none 不同，标签不可见，但在页面上为其分配了空间。标签是渲染，它只是在页面上看不到。

我正在发布更新，其中添加了长文本，以查看当您单击 “链接到隐藏 div 中的锚点”时它如何进入 hidden 元素：

$(document).ready(function(){
    $("#f-hdr").click(function(){
        $("#hidden").toggle(1000);
    });
});

p {color:#000;}

<a href="#anch">Link to anchor within hidden div</a>

<h2><a id="f-hdr" href="javascript:void(0)">Div Header</a></h2>

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
<p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).</p>
<p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.</p>
<p>There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>
