基于jQuery的判断iPad、iPhone、Android是横屏还是竖屏的代码

复制代码 代码如下:

function orient() {
if (window.orientation == 90 || window.orientation == -90) {
//ipad、iphone竖屏；Andriod横屏
$("body").attr("class", "landscape");
orientation = 'landscape';
return false;
}
else if (window.orientation == 0 || window.orientation == 180) {
//ipad、iphone横屏；Andriod竖屏
$("body").attr("class", "portrait");
orientation = 'portrait';
return false;
}
}
//页面加载时调用
$(function(){
orient();
});
//用户变化屏幕方向时调用
$(window).bind( 'orientationchange', function(e){
orient();
});
