基本上，我試圖在單擊時將單選按鈕值附加到 div。這可以正常工作，但是當單擊另一個單選按鈕時我似乎無法清除 div。div 中只能有 1 條附加數據。我嘗試在附加值之前使用innerHTML清除div，但似乎不起作用$('input[type="radio"]').one('click', function () { var getVal = $(this).val(); if ($('.selections').text().length < 0) { console.log('less than'); } else if ($('.selections').text().length > 0){ console.log('more than'); $('.selections').innerHTML = ""; $('.selections').append(getVal); } console.log(getVal);});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><form> <label> <span class="radio-c"> <input type="radio" name="q1" value="Between ￡381K and ￡450K" id="between381"> Between ￡381K and ￡450K </span> </label> <label> <span class="radio-c"> <input type="radio" name="q1" value="Over ￡450K" id="over450"> Over ￡450K </span> </label></form><div class="selections"></div>
單擊單選按鈕時，將值附加到 div 并在單擊另一個單選按鈕時從 div 中刪除
