jQuery find anchor tag with exact href
提问by jetlej
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. /imagesAND 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查找具有匹配 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以及指向该网址子文件夹的任何链接，例如。/images/recent. 如果我只要求/images.
$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 withthe match string. Instead, use =, the Attribute Equals selectorwhich requires an exact match:
您正在使用^=的属性开始，随着选择。顾名思义，它匹配值以匹配字符串开头的属性。相反，使用=的属性等于选择需要精确匹配：
$menuChildren = $menuChildren.has('a[href="'+url+'"]');

If you want to match the href exactly then use the [href=...]version
如果您想完全匹配 href 则使用[href=...]版本
$menuChildren = $('a[href="' + relativeUrl + '"]');
