更改所有活动链接javascript CSS的颜色

Question

I have several buttons on a page which change color from blue to red when pressed down. I want a reset button to reset the colors of the buttons to blue without having to reload the entire page. Is this possible?

<button id="btn" onClick="style.backgroundColor='red'; style.border='3px solid red'; style.color='#FFF';">Copy</button>

Answer 2

You can set

onmouseup="this.style.backgroundColor='blue'"

but like Andy said, you should use CSS classes, switching between them, for this kind of styles

Answer 3

This can be done with HTML+CSS+JS
