Answer 1

The jQuery constructor accepts a 2nd parameter called context which can be used to override the context of the selection.(jQuery构造函数接受名为context的第二个参数，该参数可用于覆盖选择的上下文。)

jQuery("img", this); Which is the same as using .find() like this:(这与使用.find()一样的：) jQuery(this).find("img"); If the imgs you desire are only direct descendants of the clicked element, you can also use .children() :(如果你想要的imgs 只是被点击元素的直接后代，你也可以使用.children() ：) jQuery(this).children("img");
