使用Flask将JavaScript连接到Python脚本 [英] Connect JavaScript to Python script with Flask
问题描述
我完全用HTML/CSS创建了一个网站.还可以使用Javascript进行事件(单击按钮，...).
I created an website with HTML/CSS completly on my own. Also use Javascript for events (click on button, ...).
现在我想用它连接一个python脚本，更重要的是，将python的结果返回到我的网站并在那里显示(使用)它们.考虑这样的事情:
Now i want to connect an python script with it and more important, return the results from python to my website and display (use) them there. Consider something like this:
带有输入和按钮的网站.如果单击该按钮，则应运行python脚本，如果输入的是奇数或偶数，则该python脚本将返回(当然，在这种情况下，您不需要python，但我想这样做)
Website with an input and button. If you click on the button a python script should run which returns if the input is an odd or even number (of course you dont need python for this specific case, but i want to do that)
根据我的研究，我相信Flask是执行此操作的库(?)，但我真的不知道该怎么做.我发现的例子很少.如果有人可以实现上面的示例或告诉我如何正确执行操作，我将不胜感激.
From my research i believe Flask is the library to do it (?), but i really dont know how to do it. I found very few examples. I would really appreciate if someone could implement the above example or tell me how to do it exactly.
我知道在线上已经有关于该概念的一些问题了，但是正如我所说的那样，例子很少.
I know there are already some questions about that concept here online, but as i said, with very few examples.
推荐答案
非常感谢您的帮助和所花费的时间.但是您的回答并没有以我需要的方式帮助我.那时我不知道该怎么办，但自从前一段时间(我观看了youtube视频...)弄清楚了以后，我以为我在这里分享我的解决方案(粘贴两个字符串):
I really appreciate your help and time spent. But your answer did not help me in the way I needed it. At that point I had no clue what to do but since I figured it out some time ago (I watched an youtube video...) I thought i share my solution here (stick two strings):
那是app.py:
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route('/stick', methods=['GET', 'POST'])
def stick():
if request.method == 'POST':
result = request.form['string1'] + request.form['string2']
return render_template('index.html', result=result)
else:
return render_template('index.html')
if __name__ == "__main__":
app.run()
然后是index.html(放入模板文件夹):
And that index.html (put in the folder templates):
<!DOCTYPE html>
<html>
<body>
<h3> Stick two strings </h3>
<form action="{{ url_for('stick') }}" method="post">
<input type="text" name="string1">
<input type="text" name="string2">
<input type="submit" value="Go!">
<p id="result"></p>
</form>
<script>
document.getElementById("result").innerHTML = "{{result}}"
</script>
</body>
</html>
在终端中输入 python app.py ，它应该可以正常工作.
In the terminal type in python app.py and it should work.
