Walaupun tutorial sejenis sudah banyak yang membahas, tidak salahnya juga, jika saya membahasnya lagi diblog ini, hitung hitung menambah perbendaharaan pengetahuan tentang javascript.
JavaScript
function toggleClass(selectorID,newClass){
var selector = document.getElementById(selectorID);
//metode classList
if(selector.classList)
selector.classList.toggle(newClass);
else{
//jika tidak support classList
var splitClass = selector.className.split(" "),
i = splitClass.indexOf(newClass);i>=0?splitClass.splice(i,1):splitClass.push(newClass),
selector.className=splitClass.join(" ")
}
}
HTML Example
<button onclick='toggleClass("demo","red");'>Toggle Class</button>
<div class='boxs' id='demo'></div>
Penjelasan :
- Yang bergaris bawah dengan kata
demoadalah targetIDdari element yang ditargetkan. - Yang bergaris bawah dengan kata
redadalah nama kelas (className) yang ingin disematkan.
Demo :
<!DOCTYPE html>

.boxs {
