you have to add quoet/double quote before and after the user input: because in the end , without adding the '' ,the code will be like this String(email@gmail.com);您必须在用户输入前后添加引号/双引号：因为最后，如果不添加 '' ，代码将像这样 String(email@gmail.com); so you have to add a quoet/double quote所以你必须添加一个引号/双引号
#!/usr/bin/python3
import cgi
import cgitb; cgitb.enable()
print ("Content-type:text/html\n\n")
form = cgi.FieldStorage()
email=str(form.getvalue("email")[0])
password=str(form.getvalue("password")[0])
print (email,password) # email@email.com,123456
print ("""
<!DOCTYPE html>
<html>
<body>
<script>
var email=String('"""+str(email.strip())+"""');
var password=String('"""+str(password.strip())+"""');
alert(email);
alert(password);
</script>
</body>
</html>
""")
