Trying to make a dropdown menu for changing between font families

« on: December 01, 2023 @666.27 »

okay so... I am trying to make a settings page to change various aspects of my website, mainly appearance wise. I've already gotten a toggle working for theme selection (dark/light mode) but I also want to have a dropdown menu for selecting between different font families for the entire website (and hopefully custom cursors and eventually even cursor trails too, though that's for a different day O_o)
SO basically, I've got the actual dropdown menu in place with values and id's and such, but I have pretty much no idea what to do for the JavaScript in regard to setting the variables to the selected values.
I'm planning on having the font-family property use a var(--font), but unlike the theme management (linked above) I want it to only be a lone variable controlled by the selected dropdown value (and remembered using localStorage, of course) rather than a class that sets the variables, if possible. (I don't particularly mind if I need to make classes for each font variable if it's necessary, but if there is a way to do it without that I would prefer it)
Apologies if this topic is similar to others, I'm still fairly new to using forums and couldn't find an answer to my question in here or by looking it up ^_^"

I believe you can just target the body tag and it should change everything that you haven't already set explicitly. See this JS Fiddle here:

https://jsfiddle.net/6uqLm3za/

I'm not sure how you'd save it from page to page though since I've never actually had to do that before.

HTML:
Code
<html>

<body>
  <p>
    This text should change once you've changed the dropdown below.
  </p>
  
  <p>
    Change font here:
  </p>

  <select id="fontToggle" onChange="changeFont()">
    <option value="0" selected="selected">None</option>
    <option value="courier">Courier</option>
    <option value="comic">Comic Sans</option>
    <option value="roman">Times New Roman</option>
  </select>
</body>

</html>


Code
function changeFont(){
var drop = document.getElementById("fontToggle");
var fchoice = drop.options[drop.selectedIndex].value;
var family = "";

switch(fchoice){
	case "courier":
  	family = "Courier";
    break;
	case "comic":
  	family = "Comic Sans MS";
    break;
	case "roman":
  	family = "Times New Roman";
    break;
}

console.log(family);
document.body.style.fontFamily = family;
}
