说明:
 自能解决部分适应情况,如果要完整解决该缩放和布局,仍需适配。

//函数封装
function detectZoom () {
    let ratio = 0,
        screen = window.screen,
        ua = navigator.userAgent.toLowerCase();
    if (window.devicePixelRatio !== undefined) {
        ratio = window.devicePixelRatio;
    } else if (~ua.indexOf('msie')) {
        if (screen.deviceXDPI && screen.logicalXDPI) {
            ratio = screen.deviceXDPI / screen.logicalXDPI;
        }
    } else if (window.outerWidth !== undefined && window.innerWidth !== undefined) {
        ratio = window.outerWidth / window.innerWidth;
    }
    if (ratio) {
        ratio = Math.round(ratio * 100);
    }
    return ratio;
}
//页面自动加载;
window.onload = function(){
    handleScreen();
}
