最新的内容与某些身份识别资料相近(有前述)?
原标题:Closest previous element with certain ID (with prev())?

我有一大批小wit子。 Say,

    <div id="parent">
 <div id="child1">
 </div>
 <div id="child1">
 </div>
 <div id="child2">
 </div>
 <div id="child1">
 </div>
 <div id="child1">
 </div>
</div>

如果目前是最后一名孩子,1 那么,我如何把我dow到最前的1个孩子? 对我来说,这在达到2个孩子时会中断。

最佳回答

我认为你希望:

$(this).prevAll( .child1 ).eq(0);
问题回答

首先,你的超文本标记无效。 文件中还有一个带有相同身份的成分。

http://www.w3.org/TR/html401/struct/global.html#h-7.5.2“rel=” 内容识别符号:id和类别属性

<>strong>id:

This attribute assigns a name to an element. This name must be unique in a document.

<<>strong>

This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

您可使用、<,在您目前的父母要素中获取第一个要素。

如果你目前处于父母一方的任何子女,你可以采用这样的做法。

$(this).parent().find("div:first-child");
 $(this).closest( .parent ).find( .child1:first )

我改为班级,因为你实际上只应在一页内有任何特定身份证明。
