如何在克隆表單上使用jQuery自動完成多個

Question

我試圖使用jQuery自動完成來顯示評論表單下的主持人列表，用戶可以選擇通知他們的評論。

評論系統是嵌套的，當用戶點擊之前存在的評論的「回覆」時，主評論表單的克隆被附加到該評論。自動填充功能可以在主要評論表單上正常工作，但不能在任何複製表單上使用。這是代碼的簡化版本：

<form id="myForm" action="submitComment.php" method="post" onsubmit="event.preventDefault();" > 
     <table> 
      <tr> 
       <th class="small"> Username </th> 
       <th colspan="4"> 
        <span>New Post</span><br/><br/> 
        <input name="subject" class="small" value="" placeholder="Optional subject (25 char max)." /> 
       </th> 
      </tr> 
      <tr> 
       <td>User Avatar</td> 
       <td colspan="4" > 
        <strong>Body</strong> 
        <br/> 
        <br/> 
        <textarea name="body" rows="4" placeholder="Comment body." > </textarea> 
        <br/> 
        <br/> 
        <input name="alert" class="alert" value="" placeholder="Notify mod(s) (Optional) "/> 
       </td> 
      </tr> 
      <tr> 
       <td></td> 
       <td colspan="4" ><input id="submit" type="submit" name="submit" value="Submit"/></td> 
      </tr> 
     </table> 
    </form> 

    <div id="comments"> 

     <div id="comment 1" class="comment dark">             
      <div class="comment-holder"> 
       <div class="body">Comment 1</div> 
       <div class="meta"> 
        USERNAME DATE <span class="reply"> REPLY</span> 
       </div> 
      </div> 

     </div> 

     <div id="comment 2" class="comment dark">             
      <div class="comment-holder"> 
       <div class="body">Comment 2</div> 
       <div class="meta"> 
        USERNAME DATE <span class="reply"> REPLY</span> 
       </div> 
      </div> 

     </div> 
     <div class="spacer" style="clear: both;"></div> 
    </div> 

    <script> 

     //Append Level 1 comment reply form 
     $(document).on('click','.reply',function(e){ 
      if (e.target !== this) 
       return; 

      $(this).addClass("active"); 

      var form = $('#myForm').clone(true, true); 
      var target = $(e.target); 
      var isFormAvailable = $("#myForm", target).length > 0; 
      var level = 2; 

      if(!isFormAvailable) { 
       $(e.target).append(form); 
       $('textarea', form).focus(); 
       $(form).addClass("child"); 
       $(form).append("<span class=\"cancel\" style=\"color:red\">CANCEL</span>"); 
       $(".cancel").click(function(){ 
        $(this).parents(".reply").removeClass("active"); 
        $(this).closest(form).remove(); 
       }); 
      } 
     }); 

     $(function() { 
      var availableTags = [ "@user1", "@user2", "@user3"]; 
      function split(val) { 
       return val.split(/,\s*/); 
      } 
      function extractLast(term) { 
       return split(term).pop(); 
      } 

      $("body") 
       // don't navigate away from the field on tab when selecting an item 
       .on("keydown click", ".alert", function(event) { 
       if (event.keyCode === $.ui.keyCode.TAB && 
        $(this).autocomplete("instance").menu.active) { 
        event.preventDefault(); 
       } 
       }) 
       .autocomplete({ 
       minLength: 1, 
       source: function(request, response) { 
        // delegate back to autocomplete, but extract the last term 
        response($.ui.autocomplete.filter(
        availableTags, extractLast(request.term))); 
       }, 
       focus: function() { 
        // prevent value inserted on focus 
        return false; 
       }, 
       select: function(event, ui) { 
        var terms = split(this.value); 
        // remove the current input 
        terms.pop(); 
        // add the selected item 
        terms.push(ui.item.value); 
        // add placeholder to get the comma-and-space at the end 
        terms.push(""); 
        this.value = terms.join(", "); 
        return false; 
       } 
       }); 
      }); 
    </script>

嘗試添加自動完成到新克隆的元素。
