基于变量名动态调用方法

def method1():
    print("调用了方法1")

def method2():
    print("调用了方法2")

method_name = "method1"
method = getattr(__main__, method_name)
method()

import java.lang.reflect.Method;

public class DynamicMethodCall {
    public static void method1() {
        System.out.println("调用了方法1");
    }

    public static void method2() {
        System.out.println("调用了方法2");
    }

    public static void main(String[] args) throws Exception {
        String methodName = "method1";
        Method method = DynamicMethodCall.class.getMethod(methodName);
        method.invoke(null);
    }
}

function method1() {
    console.log("调用了方法1");
}

function method2() {
    console.log("调用了方法2");
}

var methodName = "method1";
var method = window[methodName];
method();
