javascript - 无法删除/将元素类别切换回 `is-inactive`

Question

我在哪里

选择曲棍球运动员后，将其默认的 is-inactive 类别切换为 is-active 来表示。我还添加了 full 类，以防止选择 picked.is-inactive 类的玩家。

问题

一旦达到最大数量的玩家(四名守门员中的两名、十五名防守队员中的六名以及已达到该类别中 31 名前锋中的 12 名，以便“取消选择”一名球员并将其类别切换回默认的 is-inactive，然后选择另一名球员。

为了解决这个问题，我觉得我需要在函数中使用 .removeClass() 和 if-else 语句？

脚本.js

    /*-------------------------------------
    COUNT SELECTED
    --------------------------------------*/

    function countSelected() {
        $(".player").on("click", function(){

            // Checks if the maximum number of players have been selected
            // If so, return false and then do nothing
            // If not, the class will toggle from `is-inactive` to `is-active`
            if ($(this).find(".picked.full").length > 0) return false;
            $(this).find(".picked").toggleClass("is-inactive is-active");

            // Count the number of players with stars
            var starredGoaltenders = $(".player--goalie").find(".picked.is-active").length;
            var starredDefencemen = $(".player--defencemen").find(".picked.is-active").length;
            var starredForwards = $(".player--forward").find(".picked.is-active").length;

            console.log(starredGoaltenders, starredDefencemen, starredForwards);

            // The number of starred players for each position cannot exceed the following numbers
            var maxGoaltenders = 2;
            var maxDefencemen = 6;
            var maxFowards = 12;

            // If the number of starred players hits its max, a class of `is-completed` is adding to the corresponding checkmark to indicate that the task has been completed
            if (starredGoaltenders === maxGoaltenders) {
                $(".checkmark--goalie").addClass("is-completed");
                $(".player--goalie").find(".picked").addClass("full");
            }

            if (starredDefencemen === maxDefencemen) {
                $(".checkmark--defencemen").addClass("is-completed");
                $(".player--defencemen").find(".picked").addClass("full");
            }

            if (starredForwards === maxFowards) {
                $(".checkmark--forward").addClass("is-completed");
                $(".player--forward").find(".picked").addClass("full");
            }

            // If all the conditions are met show the submit vote button
            if (starredGoaltenders === maxGoaltenders && starredDefencemen === maxDefencemen && starredForwards === maxFowards) {
                $(".btn--submit").show();
                $(".btn--submit").addClass("slideLeft");
            }
        });
} countSelected();

Answer 1

当类 full 存在时，您正在执行return false，但当选择数量未满时，您不会删除它。

尝试像这样return false:

if ($(this).find(".picked.is-inactive.full").length > 0) return false;

然后像这样执行else到removeClass

$(".player--goalie").find(".picked").removeClass("full");
