通过引用外部页面中的锚点扩展隐藏的div [英] Expanding a hidden div by referring with an anchor from external page

问题描述

我有一个脚本在页面加载时隐藏（显示：无）列表中的某些div。 Div内容代表书的描述，整个列表是某种书目。每个div都有一个id，例如div1，div2等。

I have a script which hides (display:none) certain divs in the list on page load. Div contents represents description of a book, and the whole list is some sort of bibliography. Every div has an id, for example, "div1", "div2" etc.

<ul>  
<li><div class="hidden" id="div1"></li>  
<li><div class="hidden" id="div1"></li>   
...  
</ul> 

还有另一个带有菜单的页面，其中包含每个这样一个div的锚定链接：

And there's another page with a menu, which consists of anchored links to every such a div:

<ul>  
<li><a href="bibl.html#div1"></li>  
<li><a href="bibl.html#div2"></li>  
...  
</ul>  

我希望隐藏的div在单击其他页面上的链接时自动扩展。我尝试了一些window.location.href的东西，但无济于事 - 我的JS还很弱。我理解它应该采用当前url的逻辑并检查它是否为＃，然后在id属性中搜索具有右边部分的元素。非常感谢很多人。）

I want the hidden div to autoexpand when the link on another page is clicked. I tried some window.location.href stuff, but to no avail - my JS is weak yet. As I understand the logic it should take the current url and check it for "#", then search for an element with the part to the right in the id attribute. Thanks a lot kind people.)

推荐答案

你可以在目标页面上做这样的事情：

You can do something like this on the target page:

window.onload = function() {
    var hash = window.location.hash; // would be "#div1" or something
    if(hash != "") {
        var id = hash.substr(1); // get rid of #
        document.getElementById(id).style.display = 'block';
    }
};

基本上，您检查页面加载窗口的href是否附加了散列。如果是，则找到< div> 并将样式显示更改为阻止。

Essentially, you check on the page load whether the window's href has a hash attached to it. If it does, you find the <div> and change the style display to block.
