Web前端，根据浏览器宽度，自动调整网页大小

Web前端，用JS实现：根据浏览器宽度，用缩放的方式，自动调整网页大小。

JS代码如下：

function adjustZoom() {
    var reZoom = false;
    var zoom = get_cookie("zoom");
    if(zoom == undefined ){
        reZoom = true;
    }
    if(isNaN(zoom) == true){
        reZoom = true;
    }
    if(zoom != undefined && isNaN(zoom) == false){
        if(zoom == 1){
            reZoom = true;
        }
        if(zoom == 0){
            reZoom = true;
        }
    }
    if(reZoom == true){
        if(window.innerWidth > 1024){
            document.body.style.zoom = window.innerWidth / 1584;
        }else{
            document.body.style.zoom = 1;
        }
    }
}
// 初始调整
adjustZoom();
// 窗口大小改变时重新调整
window.addEventListener('resize', adjustZoom);

如果不进行自动窗口调整，在大分辨率情况下，浏览器窗口过大时，页面会不那么美观。

如果不想他人知道自己是如何实现这个功能的，可以将JS代码加密，比如用JShaman、JS-Obfuscator等提供的JS代码混淆加密服务：

JS加密结果，如下：
