如何通过使用JavaScript单击另一个元素来更改元素的字体？

Question

I'm trying to create a style guide generator that would allow someone to select a font they want to use in their project. It would have a list of fonts to choose from and then when they click on the font they would want it'll change the h1 tag so they can preview the font selected

Answer 1

Here is a simple Snippet, that does what I think your after.

 const demo = document.querySelector("h1"); for (const a of document.querySelectorAll(".select-font")) a.onclick = () => { demo.style.fontFamily = a.style.fontFamily; } 

 .select-font { margin: 10px; padding: 10px; background-color: silver; cursor: pointer; display: inline-block; width: 100px; } h1 { margin: 10px; padding: 10px; background-color: yellow; } 

 <div>Click one of the fonts</div> <div class="select-font" style="font-family: Times New Roman, Times, serif"> Times</div> <div class="select-font" style="font-family: Arial, Helvetica, sans-serif"> Arial</div> <div class="select-font" style="font-family: 'Comic Sans MS', cursive, sans-serif"> Comic</div> <br> <h1>Demo</h1> 

Answer 2

You can just use font-family css property.

From javascript you can set it like this:

document.getElementById("preview_element").style.fontFamily = "arial"
