在移動(dòng)端中我們經(jīng)常碰到橫屏豎屏的問(wèn)題，那么我們應(yīng)該如何去判斷或者針對(duì)橫屏、豎屏來(lái)寫不同的代碼呢。

css如何判斷橫屏豎屏

豎屏引用

<link rel="stylesheet" media="all and (orientation:portrait)" href="portrait.css"> 

橫屏引用

<link rel="stylesheet" media="all and (orientation:landscape)" href="landscape.css"> 

css代碼

@media screen and (orientation: portrait) { 
 /*豎屏 css*/ 
} 
@media screen and (orientation: landscape) { 
 /*橫屏 css*/ 
} 

JS判斷橫屏豎屏方法

//判斷手機(jī)橫豎屏狀態(tài)： 
window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", function() { 
 if (window.orientation === 180 || window.orientation === 0) { 
 alert('豎屏狀態(tài)！'); 
 } 
 if (window.orientation === 90 || window.orientation === -90 ){ 
 alert('橫屏狀態(tài)！'); 
 } 
 }, false);
