有沒有辦法檢索智能手機的模式?如果它處於橫向或縱向模式?所有可以在PHP中訪問?用PHP檢索風景/人像模式
看來Session不能在JS中訪問。但你可以用Cookies來做到這一點。下面是一個代碼段(未測試)
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/; domain=.example.com";
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
window.onorientationchange = function() {
/*window.orientation returns a value that indicates whether iPhone is in portrait mode, landscape mode with the screen turned to the
left, or landscape mode with the screen turned to the right. */
var orientation = window.orientation;
switch(orientation) {
case 0:
// If in portrait mode
document.getElementById("google_map").style.width="300px";
document.getElementById("google_map").style.height="200px";
eraseCookie("orientation");
createCookie('orientation','portrait','0');
break;
case 90:
// If in landscape mode with the screen turned to the left
document.getElementById("google_map").style.width="450px";
document.getElementById("google_map").style.height="325px";
eraseCookie("orientation");
createCookie('orientation','landscape','0');
break;
case -90:
// If in landscape mode with the screen turned to the right
document.getElementById("google_map").style.width="450px";
document.getElementById("google_map").style.height="325px";
eraseCookie("orientation");
createCookie('orientation','landscape','0');
break;
case 180:
// If in portrait mode with the screen flipped
document.getElementById("google_map").style.width="300px";
document.getElementById("google_map").style.height="200px";
eraseCookie("orientation");
createCookie('orientation','portrait','0');
break;
}
}
在PHP:
$orientation = $_COOKIE["orientation"];
if($orientation=="portrait"){
// do something
}else if($orientation=="landscape"){
// do something different
}else{
// fallback
}
PHP是服務器端,所以不能看東西屏幕方向。你需要使用類似Javascript的東西來檢測,然後將信息存儲在cookie/session中,然後重新加載並讀取PHP中的cookie /會話。 – BenOfTheNorth 2012-02-20 16:42:26
@BenGriffiths或使用AJAX – PeeHaa 2012-02-20 16:47:58
的確如此 - 我想這取決於一旦他們知道方向是什麼,將會做什麼。 – BenOfTheNorth 2012-02-20 16:49:31
