父类的addClass(LI) [英] addClass to parent(LI)

问题描述

我有一个元素"A"，当我单击它时，我想将父元素的(LI)类更改为selected，但是没有任何变化...

I have an element "A", when I click on it, I want to change parent element's (LI) class to selected, but nothing changes...

$(".filters-list li a").click(function () {
    $(".filters-list li").removeClass("selected");
    $(this).parent('li').addClass('selected'); // I also tried .parent().addClass
});

然后我尝试了以下代码:

Then I tried this code:

$(".filters-list li a").click(function () {
    $(".filters-list li").removeClass("selected");
    $(this).parent().get(0).addClass('selected'); // IE reports something like this: Object doesn't support addClass...
});

当我尝试使用此代码定义LI时，它只是报告了我[Object HTMLLIElement]:

When I tried to define LI with this code, it just reported me [Object HTMLLIElement]:

alert($(this).parent().get(0));

我做错了什么?

推荐答案

尝试

$(".filters-list li a").click(function (e) {
    e.preventDefault();
    $(".filters-list li").removeClass("selected");
    $(this).closest('li').addClass('selected'); // I also tried .parent().addClass
});

.closest() 将获得第一个与选择器.

.closest() will get the first element that matches the selector.
