I'm facing a beginner's challenge.
I have a div element and I want to extract the URL from the data-element attribute into a .json file
Is there a way to do this?
<div content="" id="preview" data-element="http://thereislink"
class="sampleclass"></div>
To retrieve data attributes, you have two options:
let x = document.getElementById('preview').getAttribute('data-element');
console.log(x)<div content="" id="preview" data-element="http://thereislink" class="sampleclass">Test</div>Alternatively, you can also utilize the dataset method:
let x = document.getElementById('preview').dataset.element;
console.log(x)<div content="" id="preview" data-element="http://thereislink" class="sampleclass">Test</div>When it comes to selecting an element in JavaScript, there are various options available known as JavaScript Selectors. In this particular scenario, I am choosing to target elements by their Id. By using the function getAttribute('attribute_name'), you can access any attribute of the selected element.
HTML Example:
<div content="" id="preview" data-element="http://thereislink"
class="sampleclass"></div>
JS Example:
var url= document.getElementById("preview").getAttribute("data-element");
