示意图：

html：

{# 用户管理 #}
<div id="userManageDiv" style="display: none;">
<div id="" style="margin-left: 10px;">  {# 创建用户 #}

</div>
<div id="createUserAlert" class="alert alert-danger" role="alert" style="width: 30%; margin-bottom: 6px; display: none;"></div>
<button type="button" id="createUserBtn" class="btn btn-default" data-toggle="modal" data-target="#alertTip" data-whatever="激活/封停 该账户？" style="width: 100px; margin-left: 100px;">提  交</button>

<div id="" style="margin-left: 10px; margin-top: 50px;">   {# 删除用户 #}
<h4 style="margin-top: 15px;">删除用户</h4>

<select name="deleteUsername" id="deleteUsername" class="form-control selectpicker" data-live-search="true">

</select>
</div>
<button type="button" id="deleteUserBtn" class="btn btn-default" data-toggle="modal" data-target="#alertTip" data-whatever="删除 该账户？" style="width: 100px; margin-left: 100px;">提  交</button>
</div>
</div>

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
