setAttribute('display','none') not working
提问by jason m
function classInfo(e){
document.getElementById('classRight').setAttribute('display','none');
alert(e);
}
I think this code is very straightforward bit it's not working, and is not hiding the element in question. I am getting my alert, which makes me think there is no issue.
我认为这段代码非常简单，它不起作用，并且没有隐藏有问题的元素。我收到警报，这让我认为没有问题。
Any help would be appreciated.
任何帮助，将不胜感激。

displayis not an attribute - it's a CSS property. You need to access the style object for this:
display不是属性 - 它是 CSS 属性。您需要为此访问样式对象：
document.getElementById('classRight').style.display = 'none';

尝试这个：
setAttribute("hidden", true);
