Question

在我的自动售货机代码中，如果我输入多余的资金，它不会给我更改。我在这里缺少什么？

$col.find('.aChild').append('...');

Answer 1

您的代码确实返回了更改，您只是没有使用它。

像这样修改你的代码：

计算<!DOCTYPE HTML> <html> <head> <title>Sign-In</title> <link rel="stylesheet" type="text/css" href="home.css"> <script src ="login.js"></script> </head> <body id="body-color"> <div id="Sign-In"> <fieldset style="width:30%"> <legend>LOG-IN HERE</legend> <form method="Post" action="login.php" submit =" validate()"> User:<br><input type="text" name="user" size="40"><br> Password:<br><input type="password" name="pass" size="40"><br> <input id="button" type="submit" name="submit" value="Log-In"> </form> < /fieldset> </div> </body> </html>后，将其传递给正在代码中进行更改计算的change方法。为此，请将此行添加到changeOut()方法的末尾：
```
main()
```

2. changeOut(change);方法存在轻微的逻辑错误。像这样修改它：

changeOut()

cities = []
with requests.Session() as session:
    session.headers = {
        'x-requested-with': 'XMLHttpRequest'
    }
    page = 1
    while True:
        if page >= 99:
            break
        url = f'https://www.kununu.com/de/volkswagen/kommentare/{page}'
        response = session.get(url)
        soup = BeautifulSoup(response.text, 'html.parser')
        new_comments = [
            cities.find_next_sibling('div').text.strip()
            for cities in soup.find_all('div', text=re.compile('Stadt'))
        ]
        cities += new_comments
        print(cities)
        page += 1

print(cities)  # this will print after 98 pages
