本來想在每一個tr標(biāo)簽中動態(tài)添加點擊的屬性，發(fā)現(xiàn)并不能實現(xiàn)點擊彈窗的功能，請各位大佬分析一下

• 彈窗代碼

<div class="modal" id="machemodal">                                                       
    <div class="modal-dialog">                                                            
        <div class="modal-content">                                                       
          <div class="modal-header">                                                      
              <h4 class="modal-title" align="center">設(shè)備詳情</h4>                            
          </div>                                                                          
          <div class="modal-body">                                                        
            <p> -----</p>                                                                 
          </div>                                                                          
          <div class="modal-footer">                                                      
            <button type="button" class="btn btn-default" data-dismiss="modal">關(guān)閉</button>
          </div>                                                                          
        </div>                                                                            
    </div>                                                                                
</div>                                                                                    

• js添加屬性代碼

 $(document).ready(function() {
         $('tr').each(function () {
             $(this).on("click", function() {
                 $("#machemodal").modal("toggle");
             })
         });
    });
