我有以下嵌套<ul> <li>
菜单结构:
<ul class="tree-0">
* #<li>
<a> Root Category </a>
<ul class="tree-1">
* <li>
<a href="/Home/Products/1">Category 1</a>
<ul class="tree-2">
* <li><a href="/Home/Products/11">SubCategory 1.1</a></li>
* <li><a href="/Home/Products/12">SubCategory 1.2</a></li>
</ul>
</li>
# <li>
<a href="/Home/Products/2">Category 2</a>
<ul class="tree-2">
* # <li><a href="/Home/Products/21">Category 2.1</a></li>
<li><a href="/Home/Products/22">Category 2.2</a></li>
</ul>
</li>
</ul>
</li>
</ul>
我想选择所有类别的 2.1 类型的父母<ul>
,直到达到 root ul
。所以我的代码如下:
URL: localhost:22342/Home/Products/21
//Get the `<a>` tag which has the href equal to the pathname
var a = jQuery("a[href='" + window.location.pathname + "']"); //Suppose its Category 2.2
//Get ul parents of <a>
var parents = jQuery(a).parents("ul");
//Loop through the parents array()
for (var i = 0; i < parents.length; i++) {
console.log(jQuery(parents[i]).attr("level")); // check if looping occurs till root
jQuery(parents[i]).find("li:first").css("background","blue"); // apply a class to first child of the parent element.
}
问题:蓝色背景应用于用 * 制作的部分,但我希望用 # 标记部分。
