When getting the list elements in ul, we use get element by class name or tag and are returned in an array
var targetImages = document.getElementById("image-list-view").getElementsByTagName("img");
I need to get the element image in this list and i seem to be stack
<ul id="image-list-view">
<li>
<a href="#" data-gallery>
<img src="images/pic1.jpg"/>
</a>
</li>
<li>
<a href="#" data-gallery>
<img src="images/pic2.jpg"/>
</a>
</li>
</ul>
EDIT
Sorry i didnt explain the problem with the code.
the code works fine when the site starts but targetImages
can no longer be accessed later or referenced ie (images cannot be accessed);
Your code works, you just need to loop thru the results and do something with the images.
getElementsByTagName
returns anHTMLCollection
, which is almost like an array. You can loop thru it the same way.
var targetImages = document.getElementById("image-list-view").getElementsByTagName("img"); for (var i = 0; i < targetImages.length; i++) { console.log(targetImages[i]); }
I need to get the element image in this list and i seem to be stack <ul id="image-list-view"> <li> <a href="#" data-gallery> <img src="images/pic1.jpg" /> </a> </li> <li> <a href="#" data-gallery> <img src="images/pic2.jpg" /> </a> </li> </ul>
Use the function querySelectorAll
along with this selector ul#image-list-view li img
.
This approach allows you to get the image elements straightforward and avoid a second function execution. Further, this approach doesn't return
null
value if the element with idimage-list-view
doesn't exist.
var targetImages = document.querySelectorAll("ul#image-list-view li img"); console.log("Count of images: " + targetImages.length);
.as-console-wrapper { max-height: 100% !important; top: 0; } ul { display: none }
<ul id="image-list-view"> <li> <a href="#" data-gallery> <img src="images/pic1.jpg" /> </a> </li> <li> <a href="#" data-gallery> <img src="images/pic2.jpg" /> </a> </li> </ul>
document.querySelectorAll()
Returns a list of the elements within the document (using depth-first pre-order traversal of the document's nodes) that match the specified group of selectors. The object returned is a NodeList.
