JavaScript style.display="none" or jQuery .hide() is more efficient?
提问by Maninda
document.getElementById("elementId").style.display="none"
is used in JavaScript to hide an element. But in jQuery,
在 JavaScript 中用于隐藏元素。但是在 jQuery 中，
$("#elementId").hide();
is used for the same purpose. Which way is more efficient? I have seen a comparison between two jQuery function .hide()and .css("display","none")here.
用于相同的目的。哪种方式效率更高？我已经看到了两个 jQuery 函数.hide()和.css("display","none")这里的比较。
But my problem is whether pure JavaScript is more efficient than jQuery?
但我的问题是纯 JavaScript 是否比 jQuery 更有效？

Talking about efficiency:
谈效率：
document.getElementById( 'elemtId' ).style.display = 'none';
What jQuery does with its .show()and .hide()methods is, that it remembers the last stateof an element. That can come in handy sometimes, but since you asked about efficiency that doesn't matter here.
jQuery 用它的.show()和.hide()方法做的是，它记住元素的最后状态。这有时会派上用场，但既然你问的效率在这里并不重要。

对比
a(2);
function a(nb) {
lot;
of = cross;
browser();
return handling(nb);
}
In youropinion, what do you think is going to be the fastest?
在您看来，您认为最快的是什么？

Efficiency isn't going to matter for something like this in 99.999999% of situations. Do whatever is easier to read and or maintain.
在 99.999999% 的情况下，效率对于这样的事情来说并不重要。做任何更容易阅读和/或维护的事情。
In my apps I usually rely on classes to provide hiding and showing, for example .addClass('isHidden')/.removeClass('isHidden')which would allow me to animate things with CSS3 if I wanted to. It provides more flexibility.
在我的应用程序中，我通常依靠类来提供隐藏和显示，例如.addClass('isHidden')/.removeClass('isHidden')，如果我愿意，我可以使用 CSS3 为事物设置动画。它提供了更多的灵活性。
