如果元素具有類別，則切換複選框

Question

我還有一個包含元素的列表，如果單擊該元素，該類將獲得「添加」類。這個元素將被轉移到表單中。因此，我列出了與列表中的'li'具有相同類的複選框。

我寫了一個jQuery腳本，它應檢查'li'是否被點擊（hasClass），然後正確的複選框應該具有'checked'屬性。但它不能正常工作。不知道是什麼我已經錯了...

HTML：

<div class="container"> 
        <div class="row row-centered konf-wrapper-1"> 
         <div class="col-md-4 label-wrap"> 
          <h1 class="header-label">Konzeption</h1> 
          <ul class="li-wrap"> 
           <li class="added haken">Kommunikationsstrategie</li> 
           <li class="0 hide-me add-btn point">Zielgruppendefinition</li> 
          </ul> 
         </div> 

         <div class="col-md-4 label-wrap"> 
          <h1 class="header-label">Kommunikationsmaßnahmen</h1> 
          <ul class="li-wrap"> 
           <li class="1 hide-me add-btn point">Namensfindung & Logoentwicklung</li> 
           <li class="2 hide-me add-btn point">Exposé</li> 
           <li class="3 hide-me add-btn point">Textdesign</li> 
           <li class="4 hide-me add-btn point">Anzeigenkampagnen</li> 
           <li class="5 hide-me add-btn point">Außenwerbung</li> 
           <li class="6 hide-me add-btn point">Bautafelgestaltung</li> 
          </ul> 
         </div> 
        </div> 

        <div class="row row-centered konf-wrapper-2 label-wrap"> 
         <div class="col-md-4 label-wrap"> 
          <h1 class="header-label">Online-Marketing</h1> 
          <ul class="li-wrap"> 
           <li class="8 hide-me add-btn point">Website</li> 
           <li class="9 hide-me add-btn point">Social Media</li> 
           <li class="10 hide-me add-btn point">Digitale Präsentation</li> 
          </ul> 
         </div> 

         <div class="col-md-4 label-wrap"> 
          <h1 class="header-label">Virtuelle Welten</h1> 
          <ul class="li-wrap"> 
           <li class="11 hide-me add-btn point">Innenvisualisierung</li> 
           <li class="11 hide-me add-btn point">Außenvisualisierung</li> 
           <li class="12 hide-me add-btn point">Virtuelle Begehung</li> 
           <li class="13 hide-me add-btn point">Augmented Reality</li> 
          </ul> 
         </div> 
        </div> 
        <button type="button" class="btn btn-primary added-btn" title="Zur Übersicht." id="gesamt-weiter" >Zum Formular</button> 



       </div> 

複選框：

<div class=""> 
     <ul class="checker-wrap"> 
     <li><input type="checkbox" id="0" value="Zielgruppendefinition" class="0 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="2" value="Exposé" class="2 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="3" value="Textdesign" class="3 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="4" value="Anzeigenkampagnen" class="4 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="5" value="Außenwerbung" class="5 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="6" value="Bautafelgestaltung" class="6 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="8" value="Website" class="8 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="9" value="Social Media" class="9 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="10" value="Digitale Präsentation" class="10 checker" name="checkbox-group[]"></li> 
     <li><input type="checkbox" id="11" value="Visualisierungen" class="11 checker" name="checkbox-group[]"></li> 
    <li><input type="checkbox" id="12" value="Virtuelle Begehung" class="12 checker" name="checkbox-group[]"></li> 
    <li><input type="checkbox" id="13" value="Augmented Reality" class="13 checker" name="checkbox-group[]"></li> 
    </ul> 
    </div> 

的jQuery：

var $check = $(".checker-wrap"); 
$(".add-btn").click(function() { 
     var $li = $(this).toggleClass("hide-me added haken"); 

     var li_class = $(this).attr('class').split(" "); 
     var $wrap = $li.closest('.label-wrap'); 
     // trigger checkbox for form 
     if (($li).hasClass("added")) { 
      $check.find('.'+li_class[0]).addAttr('checked'); 
     } else { 
      $check.find('.'+li_class[0]).removeAttr('checked'); 
     } 

     $wrap.find('h1').toggleClass('top-added', $wrap.find('.added').length > 0); 
     }); 

所以，問題是，怎樣做我必須改變，如果li添加了類，複選框會被觸發，如果不是，複選框應該取消選中...

Answer 1

使用$check.find(class_check).prop('checked', 'checked');代替.addAttr()

var $check = $(".checker-wrap"); 
 
$(".add-btn").click(function() { 
 
     var $li = $(this).toggleClass("hide-me added haken"); 
 

 
     var li_class = $(this).attr('class').split(" "); 
 
     var $wrap = $li.closest('.label-wrap'); 
 
     // trigger checkbox for form 
 
     $check.find('.'+li_class[0]).trigger('click'); 
 
     if (($li).hasClass("added")) { 
 
     var class_check = '.' + li_class[0]; 
 
      $check.find(class_check).prop('checked', 'checked'); 
 
     } else { 
 
      $check.find('.'+li_class[0]).prop('checked', false); 
 
     } 
 

 
     $wrap.find('h1').toggleClass('top-added', $wrap.find('.added').length > 0); 
 
     });
