如何删除隐藏的课程？为了显示色带？

HTML

<div id="alwaysInStockRibbon" class="ribbon-wrapper-productpage hidden">

的CSS

.hidden {
    display: none!important;
    visibility: hidden!important;

我在下面尝试过这些但没有成功。

Jquery的

$(".hidden").remove();
$(".hidden").removeClass();

https://api.jquery.com/remove/

https://api.jquery.com/removeClass/

输入

Answer 1

您需要在removeClass方法中将classname作为参数传递，以便在匹配的集合中删除它：

从匹配元素集中的每个元素中删除单个类，多个类或所有类。

 $(".hidden").removeClass('hidden');

Answer 2

$("#alwaysInStockRibbon").removeClass('hidden');

Answer 3

您必须告诉您要删除的课程。

$(".hidden").removeClass("hidden");

Answer 4

试试这个：removeClass方法需要删除类名。如果要删除多个类，可以放置空格分隔的类名

$('.hidden').removeClass("hidden");

Answer 5

或者您可以执行以下操作来显示功能区：

    String[] hexList = input.toString().split(",");
    int numHex = (int) Math.pow(9, lLevel_From_config - hLevel_From_config);
    for (String hex : hexList) {
        for (int i = 0; i < numHex; i++) {
            context.write(m_mapKey, generateHexagon(hex, i));
        }
    }
