I have a handle on an Un-ordered List (for my example i will call the handle Var1) and would like to be able to assign its last li to a variable. I tried Lastli = var1.lastChild
the only method I figured would work but it didn't. I can't seem to find a answer to this using only Javascript not jQuery any help is appreciated.
You can select the parent element and use the lastChild property.
var container = document.getElementsByTagName("ul")[0];
var lastchild = container.lastChild;
Or you select all the items into an array and get the last item. Here is a quick example:
var items = document.querySelectorAll("li");
var lastchild = items[items.length-1];
you can select all 'li' and take the last one. Something like:
var myLi = document.getElementsByTagName('li');
var lastLi = myLi[myLi.length-1];
试试这个: .childNodes[childNodes.length - 1]
either ulReference.children[ulReference.children.length -1]
or ulReference.childNodes[ulReference.childNodes.length -1]
. The difference between the two can be found here
Lets consider an example
<ul >
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>
To get the last child of the list you can simply make use of queryselector
document.querySelector('li:last-child'); //this will return Milk which is the last child of the list
document.querySelector('li:first-child') OR document.querySelector('li'); //both will give you the first child of the list
Suppose you want the n-th child for that you can use the following syntax:
document.querySelector('li:nth-child(2)'); //it will return the second child (here Tea)
If you want all the list item in the given list:
document.getElementsByTagName('li') //(Will return the whole list)here i am using tagname. It can be also applied on classname or element id
The simplest way is to use the document.querySelector
and use the :last-child
to get it.
Exemple:
const list = document.querySelector("li:last-child");
