// 屏幕旋转为横屏

// 利用 CSS3 旋转 对根容器逆时针旋转 90 度
const detectOrient = function() {

height = document.documentElement.clientHeight,
$wrapper = _this.$refs.view, // 这里是页面最外层元素

} else {
// 竖屏

style +=
"-webkit-transform: rotate(90deg); transform: rotate(90deg);";
// 注意旋转中点的处理
style +=
"-webkit-transform-origin: " +
width / 2 +
"px " +
width / 2 +
"px;";
style += "transform-origin: " + width / 2 + "px " + width / 2 + "px;";
}
// $wrapper.style.cssText = style;
document.getElementById("screen-view").style.cssText = style
};
window.onresize = detectOrient;
detectOrient();
},
注:若为app端 本方法不可行 此时采用另一种方法 亲测实用~
