如何在jQuery中选择具有多个类的元素？ 11个答案

我有一个问题是只从活动div中删除img类：

<div class="thumb thumb-selected"> <img class="img-thumb BWFilter BWfade" src="100x100.jpg" alt=""><img crossorigin="anonymous" style="height: 100px; width: 100px; margin-top: 0px; margin-left: 0px;" class="img-thumb" src="3-100x100.jpg" alt=""></div>

我想删除（BWFilter BWfade）类，只为这个div（.thumb .thumb-selected），我正在尝试使用这个jquery代码：

$('.thumb .thumb-selected').find('.img-thumb img').removeClass("BWFilter BWfade");

How can I select an element with multiple classes in jQuery? 11 answers

I have a problem to remove only img class from active div :

<div class="thumb thumb-selected"> <img class="img-thumb BWFilter BWfade" src="100x100.jpg" alt=""><img crossorigin="anonymous" style="height: 100px; width: 100px; margin-top: 0px; margin-left: 0px;" class="img-thumb" src="3-100x100.jpg" alt=""></div>

I want to remove (BWFilter BWfade) class, only for this div (.thumb .thumb-selected), I'm trying with this jquery code:

$('.thumb .thumb-selected').find('.img-thumb img').removeClass("BWFilter BWfade");

最满意答案

removeClass接受多个要删除的类：

$('.thumb.thumb-selected > img.img-thumb').removeClass('BWFilter BWfade');

> - 选择器仅在img是div的直接子项时才匹配。

参考

.removeClass（）

css - 子选择器

the removeClass accepts more then one class to remove:

$('.thumb.thumb-selected > img.img-thumb').removeClass('BWFilter BWfade');

The > - selector will only match when the img is a direct child of your div.

Reference

.removeClass()

css - child-selector
