html–模态框：

{# 模态框 #}
  <div class="modal fade" tabindex="-1" role="dialog" id="alertTip">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">×</span>
          </button>
          <h4 class="modal-title">确认提示框！！</h4>
        </div>
        <div class="modal-body">
          <p id="modal_content"></p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-primary" id="modalConfirmBtn">确认</button>
          <button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
        </div>
      </div>
    </div>
  </div>

前端js代码：

// 模态框 body显示
$(document).ready(function () {
  $('#alertTip').on('show.bs.modal', function (e) {
    var button = $(e.relatedTarget);
    var content = button.data('whatever');

    var modal = $(this);
    modal.find('#modal_content').text('确认 ' + content);
  })
});

// 模态框 显示前，记录 哪个div 启动了 模态框
var preAjaxDiv;
$(document).ready(function () {
  $('#createUserBtn').click(function () {
    preAjaxDiv = $(this).attr('id');
  });
  $('#deleteUserBtn').click(function () {
    preAjaxDiv = $(this).attr('id');
  });
  $('#changePasswordBtn').click(function () {
    preAjaxDiv = $(this).attr('id');
  });
  $('#changePermissionBtn').click(function () {
    preAjaxDiv = $(this).attr('id');
  });
});

// 模态框 点击确认后执行
$(document).ready(function () {
    $('#modalConfirmBtn').click(function () {
      if (preAjaxDiv == 'createUserBtn') {
        createUser();
        $('#alertTip').modal('hide');

      } else if (preAjaxDiv == 'deleteUserBtn') {
        deleteUser();
        $('#alertTip').modal('hide');

      } else if (preAjaxDiv == 'changePasswordBtn') {
        changePassword();
        $('#alertTip').modal('hide');

      } else if (preAjaxDiv == 'changePermissionBtn') {
        changePermission();
        $('#alertTip').modal('hide');
      }
    })
});

// 创建用户 激活/封停
function createUser() {
  var createUserAlert = '';
  $('#createUserAlert').hide();
  if ( !$('#username').val() ) {
    createUserAlert += "** 用户名不能为空！<br />";

  }
  if ( !$('#password').val() ) {
    createUserAlert += "** 密码不能为空！<br />";

  }
  if ( !$('#passwordAgain').val() ) {
    createUserAlert += "** 确认密码不能为空！<br />";

  }
  if ( $('#password').val() != $('#passwordAgain').val() ) {
    createUserAlert += "** 两次密码输入不一致！<br />";
  }
  if (createUserAlert) {
    $('#createUserAlert').html(createUserAlert);
    $('#createUserAlert').show();

  } else {
    $.ajax({
      url: '/createUser',
      type: 'POST',
      data: {
        createUsername: $('#username').val(),
        password: $('#password').val(),
        is_active: $('#userStatus').val()
      },
      success: function (data, textStatus) {
        if (data == 1) {
          alert('创建成功！');
          window.location.href = 'slg_manager_tem';

        } else if (data == -1) {
          alert('已经创建该账户，无法重复创建！');
        }
      },
      error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert(errorThrown);
      }
    })
  }
}

// 删除用户
function deleteUser() {
  $.ajax({
    url: '/deleteUser',
    type: 'POST',
    data: {
      deleteUsername: $('#deleteUsername').val()
    },
    success: function (data, textStatus) {
      if (data == 1) {
        alert('删除成功！');
        window.location.href = 'slg_manager_tem';
      }
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      alert(errorThrown);
    }
  })
}

后端python–view视图：

# 创建用户 激活/封停
@login_required(login_url='slg:login')
@require_http_methods(["POST"])
@permission_required('slg.views_slg_manager_tem', login_url='slg:get_permissionDenied')
def create_user(request):
  username = request.POST['createUsername']
  password = request.POST['password']
  is_active = request.POST['is_active']

  createResult = db_create_user(username, password, is_active)
  if createResult == 1:
    return HttpResponse('1')
  elif createResult == -1:
    return HttpResponse('-1')

# 删除用户
@login_required(login_url='slg:login')
@require_http_methods(["POST"])
@permission_required('slg.views_slg_manager_tem', login_url='slg:get_permissionDenied')
def delete_user(request):
  username = request.POST['deleteUsername']
  deleteResult = db_delete_user(username)
  if deleteResult:
    return HttpResponse('1')

后端python–models视图：

from django.contrib.auth.models import User
from django.contrib.auth import authenticate
from django.db.utils import IntegrityError
from . import db_models as db

# 创建用户 激活/封停
def db_create_user(username, password, is_active):
  if is_active == '0':
    is_active = False
  elif is_active == '1':
    is_active = True

  try:
    User.objects.create_user(username=username, password=password, is_active=is_active)
  except IntegrityError:
    return -1  # 已经创建，无法重复创建
  else:
    return 1  # 创建成功

# 删除用户
def db_delete_user(username):
  deleteResult = User.objects.filter(username=username).delete()
  if deleteResult:
    return 1
