Question

我正在使用_ foo

装饰一个函数decorator

@a_decorator(params)
def foo(x):
#    print('Called',decorator_name)
#    other magic

有没有办法访问a_decorator内的名称foo，以便我可以打印

＆＃39;称为a_decorator＆＃39;

def a_decorator(some_function):
    def wrapper():
        some_function()
        return some_val
    return wrapper

Answer 1

可以通过将装饰者名称附加到包装函数来完成：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <script type="text/javascript">
        var click = 0;
        function clicked(){
            var num = Math.floor((Math.random() * 100) + 1);

            click = click+1;
            if(num == 1){
                document.getElementById("print").innerHTML="Congratz! You did it in "+click+" times!";
                document.getElementById("press").disabled = true;
            }
            else{
                document.getElementById("print").innerHTML="Not the right number! You 've pressed "+click+" times!";
            }
        }
    </script>
</head>
<h1>TEST YOUR LUCK!</h1>
<body>
    <input type="button" value="Press Me!" id="press" onclick="clicked()">
    <div id="print"></div>
</body>
</html>

python中的函数是第一类，您可以将它们视为对象，附加属性等。
