jQuery中closest()和parents()的作用非常相似,都是向上寻找符合选择器条件的元素,但是他们之间有一些细微的差别,官网也给出了说明:
.closest() | .parents() |
---|---|
Begins with the current element | Begins with the parent element |
Travels up the DOM tree until it finds a match for the supplied selector | Travels up the DOM tree to the document’s root element, adding each ancestor element to a temporary collection; it then filters that collection based on a selector if one is supplied |
The returned jQuery object contains zero or one element for each element in the original set, in document order | The returned jQuery object contains zero or more elements for each element in the original set, in reverse document order |
以上介绍的很清楚,closest()从当前元素开始找,找到一个符合条件的对象后就返回,而parents()则是从父元素开始向上找,一直到文档根节点,返回所有符合条件的jQuery元素对象。
