I'm using the following code to find anchor tags with a matching href URL. Currently it will return anchors linking to the requested URL, eg. /images AND any links to subfolders of that url, eg. /images/recent. I would like it to only return the first if I'm only asking for /images.
我正在使用以下代码来查找具有匹配的href URL的锚标记。目前，它将返回链接到请求的URL的锚点，例如。 / images和该URL的子文件夹的任何链接，例如。 /图像/近。如果我只是要求/图像，我希望它只返回第一个。
$menuChildren = $menuChildren.has('a[href^="'+relativeUrl+'"],a[href^="/'+relativeUrl+'"],a[href^="'+url+'"]');

You're using ^=, the Attribute Starts-With selector. As its name suggests, it matches attributes whose values start with the match string. Instead, use =, the Attribute Equals selector which requires an exact match:
您正在使用^ =，Attribute Starts-With选择器。顾名思义，它匹配其值以匹配字符串开头的属性。相反，使用=，属性等于选择器，它需要完全匹配：
$menuChildren = $menuChildren.has('a[href="'+url+'"]');

If you want to match the href exactly then use the [href=...] version
如果要精确匹配href，请使用[href = ...]版本
$menuChildren = $('a[href="' + relativeUrl + '"]');
