如何在HTML中显示变量 [英] How to display a variable in HTML
问题描述
我正在制作一个使用Python的网络应用程序,并且有一个我想在HTML页面上显示的变量。我怎么能这样做呢?在HTML页面中使用 {%VariableName%}
是否是正确的方法? 解决方案
在Flask 文档所以我建议你阅读它以获得完整的理解,但这里是一个非常简单的渲染模板变量的例子。
存储在 templates / index.html
:
< html>
< body>
< p>下面是我的变量:{{variable}}< / p>
< / body>
< / html>
和简单的Flask应用程序:
from flask import Flask,render_template
app = Flask('testapp')
@ app.route('/')
def index():
返回render_template('index.html',variable ='12345')
if __name__ =='__main__':
app.run )
运行此脚本并访问 http://127.0.0.1:5000/ 在您的浏览器中。你应该看到变量
的值为 12345
I am making a web app using Python and have a variable that I want to display on an HTML page. How can I go about doing so? Would using {% VariableName %}
in the HTML page be the right approach to this?
This is very clearly explained in the Flask documentation so I recommend that you read it for a full understanding, but here is a very simple example of rendering template variables.
HTML template file stored in templates/index.html
:
<html>
<body>
<p>Here is my variable: {{ variable }}</p>
</body>
</html>
And the simple Flask app:
from flask import Flask, render_template
app = Flask('testapp')
@app.route('/')
def index():
return render_template('index.html', variable='12345')
if __name__ == '__main__':
app.run()
Run this script and visit http://127.0.0.1:5000/ in your browser. You should see the value of variable
rendered as 12345
