javascript - 遍历选择器 javascript 旁边的所有元素

Question

您好，我有一个选择框在不同的元素中具有相同的类 super-attribute-select

<dd class="clearfix swatch-attr" style="display: none;">
    <div class="input-box">
        <select name="super_attribute[327]" id="attribute327" class="required-entry super-attribute-select no-display swatch-select"
            style="display: none;">
    <option value="">Choose an Option...</option><option value="2178" price="0" data-label="not specified" selected="selected">Not Specified</option></select>
    </div>
</dd>
<dd>
    <div class="input-box field__input-wrapper">
        <select name="super_attribute[481]" id="attribute481" class="required-entry super-attribute-select field__input field__input--select"
            style="pointer-events: none;">
    <option value="">Choose an Option...</option><option value="5531" price="0" data-label="intel core i5">Intel Core I5</option></select>
    </div>
</dd>
<dd>
    <div class="input-box field__input-wrapper">
        <select name="super_attribute[500]" id="attribute500" class="required-entry super-attribute-select field__input field__input--select"
            style="pointer-events: none;">
    <option value="">Choose an Option...</option><option value="5828" price="0" data-label="8 gb ddr3">8 GB DDR3</option></select>
    </div>
</dd>
<dd>
    <div class="input-box field__input-wrapper validation-passed">
        <select name="super_attribute[542]" id="attribute542" class="required-entry super-attribute-select field__input field__input--select validation-passed">
    <option value="">Choose an Option...</option><option value="9396" price="424" data-label="3.3 ghz">3.3 GHz</option><option value="9393" price="300" data-label="3.2 ghz">3.2 GHz -BHD 124.00</option><option value="9628" price="84" data-label="3.1 ghz">3.1 GHz -BHD 340.00</option><option value="9626" price="0" data-label="2.8 ghz">2.8 GHz -BHD 424.00</option></select>
    </div>
</dd>
<dd style="display: block;">
    <div class="input-box field__input-wrapper">
        <select name="super_attribute[543]" id="attribute543" class="required-entry super-attribute-select field__input field__input--select"
            style="pointer-events: none; display: block;">
    <option value="">Choose an Option...</option><option value="9857" price="0" data-label="amd radeon r9 290x">AMD Radeon R9 290X</option></select>
    </div>
</dd>
<dd class="last">
    <div class="input-box field__input-wrapper">
        <select name="super_attribute[629]" id="attribute629" class="required-entry super-attribute-select field__input field__input--select"
            style="pointer-events: none;" disabled="">
    <option value="">Choose an Option...</option><option value="13288" price="0" data-label="1 tb">1 TB</option></select>
    </div>
</dd>

我有一个在更改选择值时触发的 js 函数

jQuery('.super-attribute-select').on('change', function () {jQuery('.super-attribute-select').each(function () {}}

当任何选择值发生变化时，我正在使用 .each 迭代这些选择框。

但我只想迭代那些在此更改选择之后出现的选择框，而不是从头到尾的所有选择。就像我更改third select box 循环迭代必须从第三个开始而不是从第一个开始。我已经尝试过.nextAll() 但它只迭代 sibling 它在我的情况下不起作用.

你可以这样做

jQuery(this).closest('dd').nextAll('dd').find('.super-attribute-select');
