对于之前在博客中说的关于手机页面页面放大问题,在这里需要更正一下之前的解决办法,因为之前的那个方法并不能使用所有情况。所以这里将说一下新的解决办法:首先在头部加一个js来获取手机的不同型号对应的并屏幕大小,然后给其加不同的meta属性。如下:

<script>     if(/Android (\d+\.\d+)/.test(navigator.userAgent)){        var version = parseFloat(RegExp.$1);     if(version>2.3){        var phoneScale = parseInt(window.screen.width)/720;        document.write('<meta name="viewport" content="width=720, minimum-scale = '+ phoneScale +', maximum-scale = '+ phoneScale +', user-scalable=no, target-densitydpi=device-dpi">');        }else{             document.write('<meta name="viewport" content="width=720, target-densitydpi=device-dpi">');        }        }else{             document.write('<meta name="viewport" content="width=720, user-scalable=no, target-densitydpi=device-dpi">');        } </script>
Copy after login

其次就是需要改你的css。即将你的css中所有定了页面最大宽度的具体值全部改成100%.这样就能解决问题了,经测试这个方法对所有常用机型都适用。
