js怎么获取窗口宽度和高度

// 获取视口的宽度和高度（不包括滚动条）
var viewportWidth = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
var viewportHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

console.log("Viewport Width: " + viewportWidth);
console.log("Viewport Height: " + viewportHeight);

// 监听窗口大小变化事件
window.addEventListener('resize', function() {
    var width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
    var height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

    console.log("Resized - Width: " + width + ", Height: " + height);
});
