如何将所选元素置于一个可信的元素中 [英] How to get the selected element inside a contenteditable element
问题描述
我检查了这个问题,以及这个,问题是它给了我当前选择的内容,但我想要取而代之的是dom元素。
I checked out this question, and this one, the problem is it gives me the content of the current selection, but I want the dom element instead.
我正在寻找一种方法来获取当前正在使用javascript编辑的元素的标记名。例如:
I'm looking for a way to get the tagname of an element that is currently being edited with javascript. For example:
<article contenteditable=true>
<h2>Some List</h2>
<ul>
<li>Item 1</li>
<li>Item *caret here* 2</li>
<li>Item 3</li>
</ul>
</article>
我希望能够将列表项放入javascript el
变量。所以我可以这样做:
I want to be able to put the list item into a javascript el
variable. So I that I can do for example:
el.tagName
el.className
有谁知道如何实现这一目标? Tx:)
Does anyone know how to achieve this? Tx :)
推荐答案
您可以使用范围指代文档的选定部分,而不是检查< ul> 的US / docs / Web / API / Range / commonAncestorContainerrel =noreferrer> commonAncestorContainer 。
在您的示例中,如果您选择列表的一部分,则可以使用以下内容检索< ul>
:
You can use a Range to refer to the selected part of the document and than check the commonAncestorContainer for retriving the <ul>
.
In your example if you select part of the list you can retrieve the <ul>
with something like:
var sel = window.getSelection();
var range = sel.getRangeAt(0);
var ulTag = range.commonAncestorContainer;
如果您想要获取光标指向的元素(没有选择),您可以请参阅 startContainer 属性,然后查看 parentNode
用于重新获取< li>
。例如:
If you instead want to get the element pointed by the cursor (without there being a selection) you can refer to the startContainer property and than check the parentNode
for retriving the <li>
. For example:
var sel = window.getSelection();
var range = sel.getRangeAt(0);
var pointedLiTag = range.startContainer.parentNode;
请注意,这些只是简单的用例,在真实文档中有很多嵌套元素,因此您必须确保在使用之前检索的元素是您所期望的元素。
