有没有办法声明事件对象而不是在函数的参数中？

function setupEvent() {
    let eventObject = { type: 'click', target: null };

    function handleEvent(event) {
        eventObject = event;
        // 现在你可以在handleEvent外部访问eventObject
        console.log('Event Type:', eventObject.type);
        console.log('Event Target:', eventObject.target);
    }

    document.addEventListener('click', handleEvent);

    // 返回一个函数，用于外部访问eventObject
    return function getEventObject() {
        return eventObject;
    };
}

const getEvent = setupEvent();

// 在需要的时候获取事件对象
document.getElementById('someElement').addEventListener('click', () => {
    const eventObj = getEvent();
    console.log('Event captured outside:', eventObj);
});

let globalEventObject = null;

function handleEvent(event) {
    globalEventObject = event;
    // 现在你可以在handleEvent外部访问globalEventObject
    console.log('Event Type:', globalEventObject.type);
    console.log('Event Target:', globalEventObject.target);
}

document.addEventListener('click', handleEvent);

// 在需要的时候获取事件对象
document.getElementById('someElement').addEventListener('click', () => {
    console.log('Event captured outside:', globalEventObject);
});
