我需要检测用户是否在旧版本以及IOS 11上的Safari中处于私有模式。是否有测试可以覆盖两者?
更新:这是一支笔,试图根据下面的jeprubio解决方案组合存储和openDatabase try-catch块
var isPrivate = false;
// Check private in iOS < 11
var storage = window.sessionStorage;
try {
console.log('first try for storage')
storage.setItem("someKeyHere", "test");
storage.removeItem("someKeyHere");
} catch (e) {
console.log('first catch')
if (e.code === DOMException.QUOTA_EXCEEDED_ERR && storage.length === 0) {
isPrivate = true;
}
}
// Check private in iOS 11: https://gist.github.com/cou929/7973956#gistcomment-2272103
try {
console.log('second try for opendb');
window.openDatabase(null, null, null, null);
} catch (e) {
console.log('second catch');
isPrivate = true;
}
console.log('isPrivate: ' + isPrivate)
alert((isPrivate ? 'You are' : 'You are not') + ' in private browsing mode');

在Safari新版本(11+)普通浏览器模式下,在控制台上的openDatabase测试中没有错误,但是输入第二个catch并且isPrivate设置为true。因此,在Safari 11+中,非私密模式也被检测为私有模式。

试试这个:
var isPrivate = false;
// Check private in iOS < 11
var storage = window.sessionStorage;
try {
storage.setItem("someKeyHere", "test");
storage.removeItem("someKeyHere");
} catch (e) {
if (e.code === DOMException.QUOTA_EXCEEDED_ERR && storage.length === 0) {
isPrivate = true;
}
}
// Check private in iOS 11: https://gist.github.com/cou929/7973956#gistcomment-2272103
try {
window.openDatabase(null, null, null, null);
} catch (_) {
isPrivate = true;
}
alert((isPrivate ? 'You\'re' : 'You aren\'t') + ' in private browsing mode');
