廢話不多說了，直接給大家貼代碼了，具體代碼如下所述：
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>fruit</title><style type="text/css">.hide { display: none;}div { float: left; width: 100%;}.selector-containter { margin-bottom: 10px;}.selector { width: 200px; background: #FFF; border: 1px solid #DDD;}.selector-hint { width: 178px; border: 1px solid #DDD;}.selector-expand { width: 8px; border: 1px solid #DDD;}.selector-collapse { width: 8px; border: 1px solid #DDD;}</style><script src="jquery-3.2.1.min.js"></script><script>$(document).ready(function() { //使用on方法，采用事件委派機制，selector-option-container中的內容為后續動態追加 $('.selector').on('click', '.selector-expand', function() { $(this).parent().children('.selector-option-container').children().remove(); $(this).parent().children('.selector-option-container').append('<div><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></div><div class="selector-option">apricot</div>'); $(this).parent().children('.selector-option-container').append('<div><input type="checkbox" name="fruitGroup" class="selector-checkbox"/></div><div class="selector-option">banana</div>'); $(this).nextAll('.selector-option-container').removeClass('hide'); }); $('.selector').on('click', '.selector-collapse', function() { $(this).nextAll('.selector-option-container').addClass('hide'); }); $('.selector-t1').on('click', '.selector-option', function() { $(this).parent().parent().children('.selector-hint').text($(this).text()); $(this).parent().addClass('hide'); }); $('.selector-t1').on('click', '.selector-checkbox', function() { $(this).parent().parent().parent().children('.selector-hint').text($(this).parent().next().text()); //采用prop方法，對于值為布爾型的屬性賦值 $(this).prop('checked', false); $(this).parent().parent().addClass('hide'); });});</script></head><body><div id="titan" class="selector-containter"><div id="fruit"> <div class="selector"> <div class="selector-hint">select fruit</div> <div class="selector-expand">+</div> <div class="selector-collapse">-</div> <div class="selector-option-container"> </div> </div></div></div><div id="athena" class="selector-t1 selector-containter"><div id="fruit"> <div class="selector"> <div class="selector-hint">select fruit</div> <div class="selector-expand">+</div> <div class="selector-collapse">-</div> <div class="selector-option-container"> </div> </div></div></div></body></html>總結
