1、JS 正则
    test   - 判断字符串是否符合规定的正则
        rep = /\d+/;
        rep.test("asdfoiklfasdf89asdfasdf")
        # true
        rep = /^\d+$/;
        rep.test("asdfoiklfasdf89asdfasdf")
        # true
    exec   - 获取匹配的数据
        rep = /\d+/;
        str = "wangshen_67_houyafa_20"
        rep.exec(str)
        # ["67"]
        JavaScript is more fun than Java or JavaBeans!
        var pattern = /\bJava(\w*)\b/;
        # ["JavaScript", "Script"]
        JavaScript is more fun than Java or JavaBeans!
        var pattern = /\bJava\w*\b/g;
        # ["JavaScript"]
        # ["Java"]
        # ["JavaBeans"]
        # null
        JavaScript is more fun than Java or JavaBeans!
        var pattern = /\bJava(\w*)\b/g;
        # ["JavaScript",'Script']
        # ["Java", ""]
        # ["JavaBeans", "Beans"]
        # null
    多行匹配：
        默认就是多行匹配
        ^$
   - 登录注册验证
        默认事件先执行：
            checkbox
        自定义先执行
            a
            submit
            ...
        <form>
            <input type='type' />
            <input type='password' />
            <input type='submit' />
        </form>
        $(':submit').click(function(){
            $(':text,:password').each(function(){
                ...
                return false;
            })
            return false;
        })
        input,checbox
    ================================== 验证 ================================
    JS： 验证
         各种验证
            $(':submit').click(function(){
                $(':text,:password').each(function(){
                    ...
                    return false;
                })
                return false;
            })

4、Django
    pip3 install django
    C:\Python35\Scripts
    # 创建Django工程
    django-admin startproject 【工程名称】
        mysite
            - mysite        # 对整个程序进行配置
                - init
                - settings  # 配置文件
                - url       # URL对应关系
                - wsgi      # 遵循WSIG规范，uwsgi + nginx
            - manage.py     # 管理Django程序： ---django也有orm框架
                                - python manage.py
                                - python manage.py startapp xx
                                - python manage.py makemigrations
                                - python manage.py migrate
    # 运行Django功能
    python manage.py runserver 127.0.0.1:8001
    chouti
        - chouti
            - 配置
        - 主站 app
        - 后台管理 app
    # 创建app
    python manage.py startapp cmdb
    python manage.py startapp openstack
    python manage.py startapp xxoo....
    app：
        migrations     数据修改表结构
        admin          Django为我们提供的后台管理
        apps           配置当前app
        models         ORM,写指定的类  通过命令可以创建数据库结构
        tests          单元测试
        views          业务代码
    创建完project之后
    1、配置模板的路径
        TEMPLATES = [
                {
                    'BACKEND': 'django.template.backends.django.DjangoTemplates',
                    'DIRS': [os.path.join(BASE_DIR, 'templates')],
                    'APP_DIRS': True,
                    'OPTIONS': {
                        'context_processors': [
                            'django.template.context_processors.debug',
                            'django.template.context_processors.request',
                            'django.contrib.auth.context_processors.auth',
                            'django.contrib.messages.context_processors.messages',
                        ],
                    },
                },
            ]
    2、配置静态目录
        static
        STATICFILES_DIRS = (
            os.path.join(BASE_DIR, 'static'),
        )
        <link rel="stylesheet" href="/static/commons.css" />
内容整理
    1. 创建Django工程
            django-admin startproject 工程名

    2. 创建APP
        cd 工程名
        python manage.py startapp cmdb
    3、静态文件
        project.settings.py
        STATICFILES_DIRS = (
            os.path.join(BASE_DIR, "static"),
        )
    4、模板路径
        DIRS ==>    [os.path.join(BASE_DIR,'templates'),]
    5、settings中
        middlerware
            # 注释 csrf
    6、定义路由规则
        url.py
            "login" --> 函数名
    7、定义视图函数
        app下views.py
            def func(request):
                # request.method   GET / POST
                # http://127.0.0.1:8009/home?nid=123&name=alex
                # request.GET.get('',None)   # 获取请求发来的而数据
                # request.POST.get('',None)
                # return HttpResponse("字符串")
                # return render(request, "HTML模板的路径")
                # return redirect('/只能填URL')
    8、模板渲染
        特殊的模板语言
            -- {{ 变量名 }}
                def func(request):
                    return render(request, "index.html", {'current_user': "alex"})
                index.html
                <html>
                ..
                    <body>
                        <div>{{current_user}}</div>
                    </body>
                </html>
                ====> 最后生成的字符串
                <html>
                ..
                    <body>
                        <div>alex</div>
                    </body>
                </html>
            -- For循环
                def func(request):
                    return render(request, "index.html", {'current_user': "alex", 'user_list': ['alex','eric']})
                index.html
                <html>
                ..
                    <body>
                        <div>{{current_user}}</div>
                        <ul>
                            {% for row in user_list %}
                                {% if row == "alex" %}
                                    <li>{{ row }}</li>
                                {% endif %}
                            {% endfor %}
                        </ul>
                    </body>
