从零开始学Flask框架-004

Flask-Moment

pip install flask-moment

除了moment.js,Flask-Moment 还依赖jquery.js。但是Bootstrap 已经引入了jquery.js,因此只需引入moment.js 即可。

templates/base.html:引入moment.js 库

{% extends "bootstrap/base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{% block title %}Flasky{% endblock %}
{#引入moment.js 库#}
{% block scripts %}
{{ super() }}
{{ moment.include_moment() }}
{% endblock %}

{#包含导航条的程序基模板#}
{% block navbar %}
<div class="navbar navbar-inverse" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle"
data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="/">TEST</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li><a href="/">Home</a></li>
</ul>
</div>
</div>
</div>
{% endblock %}
{% block content %}
<div class="container">
{% block page_content %}{% endblock %}
</div>
{% endblock %}

templates/index.html:

{% extends "base.html" %}
{% block title %}IndexTitle{% endblock %}
<div class="container">
    {% block page_content %}
        <h1>Hello Flask!</h1>
        <p>本地时间格式化:{{ moment(current_time).format('YYYY-MM-DD HH:mm:ss') }}.</p>
        <p>本地时间格式化:{{ moment(current_time).format('YYYY-MM-DD') }}.</p>
        <p>本地时间格式化:{{ moment(current_time).format('YYYY') }}.</p>
{#         {{ wtf.quick_form(form) }}#}
{#        你刚输入的姓名是:#}
{#        {{ name }}#}
    {% endblock %}
</div>

index.py

from flask import Flask,render_template
from flask_bootstrap import Bootstrap
from flask import request,url_for
from flask_moment import Moment
from datetime import datetime

#初始化
app = Flask(__name__)
bootstrap = Bootstrap(app)
# 初始化实例
moment = Moment(app)

#路由,处理URL 和函数之间关系的程序称为路由
@app.route('/')
#视图函数,函数执行,返回结果
def index():
    return render_template('index.html',current_time=datetime.utcnow())

#启动服务器
if __name__ == '__main__':
    app.run()
