原理
利用开启隐身模式的chrome浏览器不能通过 requestFileSystem Api 访问系统文件的特点作为hack依据进行检测。
检测函数
/**
* Determine wheter the incognito mode of Google Chrome is available or not.
*
* @param callback Anonymous function executed when the availability of the incognito mode has been checked.
*/
function isIncognito(callback){
var fs = window.RequestFileSystem || window.webkitRequestFileSystem;
if (!fs) {
callback(false);
} else {
fs(window.TEMPORARY,
100,
callback.bind(undefined, false),
callback.bind(undefined, true)
);
}
}
How to use
isIncognito(function(itIs){
if(itIs){
console.log("我是隐身模式");
}else{
console.log("我不是隐身模式");
}
});
