jQuery上下文选择器与.find() [英] jquery context selector vs .find()

问题描述

什么更有效?

var container = $("#container");

// 1
var links1 = container.find("a");

// 2
var links2 = $("a", container);

我个人更喜欢$("a", container)，因为它看起来更好，但是它们的性能有所不同吗?

I personally prefer $("a", container) because it looks better, but are they different in performance?

推荐答案

将上下文选择器$("a", container)转换为find. find()会更快，但是在大多数情况下可以忽略不计.我会选择find()，因为它的语法对我来说是相当正确的.此 帖子 具有性能比较，可帮助您确定哪个您会使用的一种.

The context selector $("a", container) is converted to find. find() will be faster but in most cases this could be ignored. I would go for find() as its syntax is quite stright forward for me. This post has performance comparison that would help you deciding which one you would use.
