問(wèn)題：如何更改 Span 類與選擇字段選項(xiàng)屬性匹配的 Span 內(nèi)的文本？并且還使其靈活，這樣我就不需要對(duì)所有屬性和跨類進(jìn)行硬編碼？我想我需要一些解決方案，其中 JS 函數(shù)搜索跨度類并將其與選項(xiàng)屬性進(jìn)行匹配，如果存在匹配，則應(yīng)更新跨度文本。帶有選項(xiàng)屬性的演示選擇字段<select class="conditional-element-selector">    <option value="select-element-1" weight="12" size="20" persons="10">Option 1</option>    <option value="select-element-2" weight="24" size="40" persons="20">Option 2</option>    <option value="select-element-3" weight="48" size="80" persons="40">Option 3</option></select>演示 HTML，其中 span 需要根據(jù)與 span 類匹配的選項(xiàng)屬性進(jìn)行更改<div class="conditional-element-1">       <li>Weight: <span class="weight">12</span> kg </li>    <li>Persons: <span class="persons">10</span></li>    <li>Size: <span class="size">20</span> m3 </li></div>我想創(chuàng)建 JS 函數(shù)來(lái)搜索選項(xiàng)屬性并搜索“.conditional-element-1”內(nèi)的跨度類如果存在匹配，則更新范圍文本。我還需要能夠添加更多屬性和跨度。$('select.conditional-element-selector').on('change', function() {  var targetIndex = this.selectedIndex + 1; // This looks at which option is selected  $('.conditional-element-' + targetIndex).... // This is unfinshed // Extend function here to match different span classes with different option attributes and change span text });
