closest和parents的主要区别是:1,前者从当前元素开始匹配寻找,后者从父元素开始匹配寻找:2,前者逐级向上查找,直到发现匹配的元素后就停止了,后者一直向上查找直到根元素,然后把这些元素放进一个临时集合中,再用给定的选择器表达式去过滤:3,前者返回0或1个元素,后者可能包含0个,1个,或者多个元素. closest对于处理事件委托非常有用.…

分类: 前端开发 parent是找当前元素的第一个父节点,不管匹不匹配都不继续往下找 parents是找当前元素的所有父节点  closest() 是找当前元素的所有父节点 ,直到找到第一个匹配的父节点 1.parent()方法从指定类型的直接父节点开始查找,在"0"中,<a>的直接父节点是<li>所以在这里找不到<ul>父节点.在"2"中先找到了<li>,接着找到<ul>,并将它的背景色设置为yellow…
jquery的parent(),parents(),parentsUntil(),closest()都是向上查找父级元素,具体用法不同 parent():取得一个包含着所有匹配元素的唯一父元素的元素集合. parents():沿 DOM 树向上遍历,直到文档的根元素(<html>)为止,将每个祖先元素添加到一个临时的集合:如果应用了选择器,则会基于该选择器对这个集合进行筛选.返回零个.一个或多个元素. closest():沿 DOM 树向上遍历,直到找到已应用选择器的一个匹配为止.返回零个或一…
