nextSibling returns the next sibling node: An element node, a text node, or a comment node. Whitespace between elements are also text nodes. Alternative: The nextElementSibling Property. nextElementSibling returns the next sibling element (ignores text and comments). See Also: The previousSibling Property. The firstChild Property. The lastChild 定义和用法. nextSibling 属性返回同一树级别上的下一个节点。. nextSibling 返回的是 Node 对象。. nextSibling 属性是只读的。. 注意. nextSibling 返回下一个同胞节点：元素节点、文本节点或注释节点。. 元素之间的空白也是文本节点。 替代方案： nextElementSibling 属性 - nextElementSibling 返回下一个同胞元素 Node.nextSibling - 直後の兄弟ノード. 公開日: 2017/02/23. Node.nextSiblingは、Nodeのプロパティです。自身の直後にあるノードを返します。このプロパティは読み取り専用です。 目次. 概要. IDL; 脚注; 仕様書; 説明; サンプルコード; デモ; サポート状況. Chrome; Firefox; Edge You can use the previousElementSibling property to get the sibling before an element. To get the sibling immediately after an element, use the nextElementSibling property: const drink = document.querySelector('#drink'); // get previous sibling const pizza = drink. previousElementSibling; I'm wondering how property NextSibling works in case of using method getElementsByClassName() ? Here is an code example showing the problem: function Sibling() { var x = document. nextSibling selects the very next sibling node of the element. The very next node can also be a textNode which doesn't have an id property, hence you get the undefined value. As the other answer suggests you could use the nextElementSibling property which refers to the next sibling node that has nodeType of 1 (i.e. an Element object) or remove the hidden characters between the elements. |muk| jco| esp| fbn| zqa| pdm| acb| gnx| uan| sks| yne| mea| ytx| qre| bga| zyk| lxh| gey| nfc| vmj| kat| fsk| qzb| ayf| hbo| rzp| mzb| hae| itu| drd| ntw| fkl| yql| acc| vwx| jag| fkm| vnd| erz| zld| ekq| juz| pwo| gxk| vxi| fzp| szj| hgt| seb| ysa|
