Can anyone help me with this code snippet I have?
<i class="my-class" title="AB">
::before
</i>
I need to extract and output the value of the title attribute, which is AB
Example output should be:
<span class="my-class">AB</span>
I've searched online but haven't found a solution yet. Any guidance would be highly appreciated.
Thank you!
Forget about Javascript, CSS is all you need for this task.
.my-class::before {
content: attr(title);
}<i class="my-class" title="AB"></i>To grab the information, simply utilize the getAttribute method:
var newSpan = document.createElement("span");
newSpan.innerText = document.querySelector(".my-class").getAttribute("title");
Utilizing CSS, you have the ability to define the content of pseudo elements (::before and ::after) as shown below:
.my-class::before {
content: "I am some unique text!";
}
By leveraging the CSS function attr(), you can populate the pseudo element's content with an attribute from your element:
.my-class::before {
content: attr(data-text);
}
It is important to note that if you add extra text within the element's content tag like
<span class="my-class" data-text="Some Text">Hello, I am different Content!</span>
it will be displayed as
Some TextHello, I am different Content!
To access a DomElement using JavaScript, you can choose from methods like document.getElementById, document.getElementsByClassName, document.querySelector, and document.querySelectorAll.
Then, retrieve the data-text attribute through HtmlElement.getAttribute and insert it as a string into the element's textContent:
const element = document.querySelector('.my-class');
element.textContent = element.getAttribute('data-text');
