拿来主义-点select复选框显示隐藏div

点select复选框显示隐藏div，HTML代码是基于bootstrap v5.1框架来的，主要是注意data-related-item="carrierAlliance"和id="carrierAlliance"的使用。

1、效果：

2、HTML

<div class="d-flex align-items-center">

    <div class="">
        <input type="checkBox" class="form-check-input" id="carrier" data-related-item="carrierAlliance">
        <label class="form-check-label" for="carrier">
            指定船公司
        </label>
    </div>

    <div class="hideArea">
        <label for="" class="label_required1 col-form-label">船公司：</label>
        <select class="form-select form-select-sm" aria-label="Default select example">
            <option selected>MSC</option>
            <option value="1">HPL</option>
        </select>
        <label for="lineCode" class="col-form-label">航线代码：</label>
        <input type="text" class="form-control form-control-sm" id="lineCode" placeholder="请输入">
        <label for="cutOff" class="col-form-label" id="carrierAlliance">截关/开航：</label>
        <input type="text" class="form-control form-control-sm" id="cutOff" placeholder="请输入">
    </div>

</div>

3、js

function evaluate() {
    var item = $(this);
    var relatedItem = $("#" + item.attr("data-related-item")).parent();

    if (item.is(":checked")) {
        relatedItem.fadeIn();
    } else {
        relatedItem.fadeOut();
    }
}

$('input[type="checkBox"]').click(evaluate).each(evaluate);
