function checkMobileSize() {
    var width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
    var height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

    if (width < 600) {
        console.log("手机屏幕尺寸较小");
    } else if (width >= 600 && width < 1024) {
        console.log("手机屏幕尺寸中等");
    } else {
        console.log("手机屏幕尺寸较大");
    }
}

// 调用函数
checkMobileSize();

// 监听窗口大小变化
window.addEventListener('resize', checkMobileSize);

function checkDeviceSize() {
    var screenWidth = window.screen.width;
    var screenHeight = window.screen.height;

    if (screenWidth < 600) {
        console.log("手机屏幕尺寸较小");
    } else if (screenWidth >= 600 && screenWidth < 1024) {
        console.log("手机屏幕尺寸中等");
    } else {
        console.log("手机屏幕尺寸较大");
