web*_*org -2 python jinja2 flask
我有简单的2行代码:
@app.route('/contact/')
def contact():
flash('We are reachable at ')
return render_template('contact.html')
我在/ contact处收到"我们可以到达"的消息但它看起来是正常的短信.它不是背景颜色(蓝色)或在秒后消失.其中contact.html包含
{% extends "layout.html" %}
{% block title %}Contact{% endblock title %}
{% block body %}
<h2> Contact Us </h2>
Your email address must be valid as this is where reply
will be sent. We do not share this address with anybody.
{% endblock body %}
请看看这个.这可能对你有帮助
<!doctype html>
<title>My Application</title>
{% with messages = get_flashed_messages() %}
{% if messages %}
<ul class="flashes">
{% for message in messages %}
<div class="message_flash">{{ message }}</div>
{% endfor %}
</ul>
{% endif %}
{% endwith %}
{% block body %}
{% endblock %}
和做一些造型 css
p {
color:blue;
}
并jquery在代码中添加一些内容
$(function() {
// setTimeout() function will be fired after page is loaded
// it will wait for 5 sec. and then will fire
// $(".message_flash").hide() function
setTimeout(function() {
$(".message_flash").hide('blind', {}, 500)
}, 5000);
})
希望这对你有所帮助.
