[英]detecting iphone/ipad orientation not working
I have this simple script:我有这个简单的脚本:
function orientation() {
var orientation = window.orientation;
switch(orientation) {
case 0:
alert('0');
break;
case 90:
alert('90');
break;
case -90:
alert('-90');
break;
}
}
$(document).ready(function(){
window.onorientationchange = orientation();
})
but somehow I never get an alert on my ipad when I turn it... Have I made a mistake somewhere?但不知何故,当我转动它时,我从未在 ipad 上收到警报……我在某个地方犯了错误吗? Thanks for your help guys:).
谢谢你们的帮助:)。
Here:这里:
window.onorientationchange = orientation;
You need to assign the function itself not the result of its execution.您需要分配 function 本身而不是其执行结果。
