在iPad上无法通过PHP或Javascript读取cookie

Question

我在尝试使用PHP或Javascript读取cookie时遇到了一些问题.我尝试过使用:

if(!$_COOKIE['popup_closed']
&& !isset($_COOKIE['username'])
&& !isset($_COOKIE['password'])
)

我试过了:

if(
$.cookie('popup_closed') == null
&& $.cookie('username') == null
&& $.cookie('password') == null) {
doStuff();
}

(使用jquery.cookie插件)

它们都不适用于iPad.它适用于所有浏览器,我试过谷歌搜索问题但似乎没有太多关于在iPad上阅读cookie的信息.

谢谢你们给予的任何帮助!

这实际上是一种解决方法,但如果它可用,你可以使用本地存储 - 至少我已成功地在iPad/iPhone中使用它.

例如,使用这种解决方案.

function saveData(name, value) {
    if (typeof(localStorage) != 'undefined') {
        localStorage.setItem(name, value);
    } else {
        createCookie(name, value, 7);
    }
}

function loadData(name) {
    var temp_value = '';

    if (typeof(localStorage) != 'undefined') {
        temp_value = localStorage.getItem(name);
    } else {
        temp_value = readCookie(name);
    }

    return temp_value;
}

function eraseData(name) {
    if (typeof(localStorage) != 'undefined') {
        localStorage.removeItem(name);
    } else {
         eraseCookie(name);
    }

}

function createCookie(name,value,days) {
    var expires = "";

    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = "; expires=" + date.toGMTString();
    }
    else {
        expires = "";
    }
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') {
            c = c.substring(1,c.length);
        } 
        if (c.indexOf(nameEQ) === 0) {
            return c.substring(nameEQ.length, c.length);
        }
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}
