Question

我正在设计一个页面，用户将在其中单击删除链接，应该出现一个模态来确认删除。但是当我单击模式上的确认按钮时，什么也没发生。

这是我的代码：

查看页面：

<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true" id="removeTeacherModal">

<div class="modal-dialog" role="document">
<div class="modal-content">
  <div class="modal-header">
    <h5 class="modal-title" id="exampleModalLabel">Remove Teacher</h5>
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
      <div class="modal-body">
      <div id="remove-messages"></div>
      <p>Do you really want to remove ?</p>
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary" id="removeTeacherBtn">confirm</button>

  </div>
</div>

控制器页面：

  $button ='
<div class="dropdown text-center">
    <button class="btn btn-secondary dropdown-toggle" type="button"     id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-    expanded="false">
            Action
     </button>
          <ul class="dropdown-menu" aria-labelledby="dropdownMenu2">
          <li><a class="dropdown-item" type="button" data-toggle="modal" data- target="#updateTeacherModal"  onClick="editTeacher('.$value['staff_id'].')">Edit</a></li>

          <li><a class="dropdown-item" type="button" data-toggle="modal" data- target="#removeTeacherModal"  onClick="removeTeacher('.$value['staff_id'].')">Remove</a></li>

        </div> ';

上面的部分是一个属性，之后将在页面上动态添加

此功能也包含在控制器页面中

public function removeT($teacherId = null){
        $validator= array('success' => FALSE , 'messages' => array());
        if($teacherId){
            $remove= $this->model_staff->remove($teacherID);
            if($remove){

                $validator['success']=true;
                $validator['messages']='Teacher is removed Successfully';
            }
            else{
                $validator['success']=false;
                $validator['messages']='Error while removing the information';    
            }  
        }
        echo json_encode($validator); 
    }

型号：

public function remove($teacherId = null){
    if($teacherId){
        $this->db->where('staff_id', $teacherId);
        $result = $this->db->delete('staff');
        return ($result == true) ? true : false;
    }   
}

Javascript：

    function removeTeacher(teacherId = null){

      if(teacherId){

         $('#removeTeacherBtn').unbind('click').bind('click', function() {

            $.ajax({
            url: base_url + 'staff/removeT/'+teacherId ,
            type:'post',
            dataType :'json' ,
            success: function(response){
                if (response.success == true){
                   $('#messages').html('<div class="alert alert-success  alert-dismissible fade show" role="alert">'+
      '<button type="button" class="close" data-dismiss="alert" aria- label="Close"><span aria-hidden="true">&times;</span></button>'+  response.messages +
    '</div>');
                manageTeacherTable.ajax.reload(null,false);
                $('#removeTeacherModal').modal('hide');

                }

                else {
                    $('#remove-messages').html('<div class="alert alert-  warning alert-dismissible fade show" role="alert">'+
     '<button type="button" class="close" data-dismiss="alert" aria-   label="Close"><span aria-hidden="true">&times;</span></button>'+    response.messages +
   '</div>');     
                }
               }    
            });
       });     
      }
  }

Codeigniter，Ajax根据无法使用的ID删除人员
