移動端H5頁面兼容性問題小結

1. input框 邊框的在ios下顏色變淡問題

input:disabled{

    　border: 1px solid #017BBA;

     　-webkit-opacity:1;

       opacity: 1;

}

2. iphone7下 橫屏之后字體變大

　　css中加入以下代碼：

@media screen and (max-device-width: 320px){body{-webkit-text-size-adjust:100%}}

@media screen and (max-device-width: 480px){body{-webkit-text-size-adjust:100%}}

@media only screen and (-webkit-min-device-pixel-ratio: 2){body{-webkit-text-size-adjust:100%}}

如何沒有效果，就單獨在標簽上設置樣式 -webkit-text-size-adjust:100%

3. H5頁面禁止橫屏　

uc瀏覽器強制豎屏

<meta name="screen-orientation" content="portrait">

 QQ瀏覽器強制豎屏

<meta name="x5-orientation" content="portrait">

iphone safari瀏覽器沒有查到可以使用meta，以上應該會有兼容性問題（沒有測），我是使用的是js方法，當橫屏的時候顯示一個頁面，告訴用戶“為了您的良好體驗，請使用豎屏”

js方式

    };
 })();

css中需添加一個樣式：

       .rotateScreenClass{

            display: none;

        }

 4.  ORC上傳身份證正反面時，如果用戶手機水平與地面拍照時，橫屏或者豎屏拍身份證會出現上傳的圖片顯示不正常（還沒解決。。。）

　　試過的方法：引入exif.js,獲取到Orientation的值，根據Orientation的值進行判斷旋轉

　　此種方法適用於手機垂直或與地面有角度時，即當手機水平與地面拍照時，是沒有橫屏和豎屏之分的，沒有辦法判斷方向

 5 . 待續
