javascript change css class

Temperature: 0 °C

使用classList是一個方便的替代方法,可以將元素的類列表作為空格分隔的字符串來訪問。
document.getElementById("MyElement").classList.add('MyClass');
document.getElementById("MyElement").classList.remove('MyClass');
if ( document.getElementById("MyElement").classList.contains('MyClass') )
document.getElementById("MyElement").classList.toggle('MyClass');

不幸的是,這些在Internet Explorer v10之前的版本中不起作用。

但我想這些應該都是已經是不變的事實~所以也不意外了。

Internet Explorer 永遠都是工程師的惡夢( ̄∇ ̄)
