I have:
const items = document.querySelectorAll('#players li'); console.log(items[0], items[1], items[2]);
<section id="players"> <h1>Players</h1> <ol> <li>Alice</li> <li>Bob</li> <li>Cesar</li> </ol> </section>
Producing:
Players
1.Alice
2.Bob
3.Cesar
Now I want convert the integers to Roman numerals, using javascript, externally in my javascript file, instead of setting the numerals in the HTML-file, like this:
<ol type="i">
<li>First</li>
<li>Second</li>
<li>Third</li>
</ol>
This is my Javascript code so far, but I want to to convert the numbers to numerals:
const items = document.querySelectorAll('#players li');
console.log(items[0], items[1], items[2]);
Just adjust your list with the type
attribute;
document.querySelector("ol").type = "I"; const items = document.querySelectorAll('#players li'); console.log(items[0], items[1], items[2]);
<section id="players"> <h1>Players</h1> <ol> <li>Alice</li> <li>Bob</li> <li>Cesar</li> </ol> </section>
You can just querySelect the parent 'ol' and then change it's list style in Javascript using element.style.listStyleType = "upper-roman". This should apply the style its child elements.
you can change type attribute of the ol tag reference
const items = document.querySelectorAll('#players li'); document.querySelector("ol").type = "i"; console.log(items[0], items[1], items[2]);
<section id="players"> <h1>Players</h1> <ol> <li>Alice</li> <li>Bob</li> <li>Cesar</li> </ol> </section>
