我试图在localstorage中缓存JSON数据,以便在没有互联网连接时加载它.它工作正常,但当我重新启动应用程序时,我认为本地存储已清除

这是我的代码:

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {

    document.addEventListener("offline", function() {
    alert("No internet connection");


    $.each(JSON.parse(localStorage.getItem('foo')), function(key, val) {
    if(!(val.php)){val.php=0;}
$('ul.get-mertchant').append('<li> <a href="azkadenya.html?id=' + val.nid + '&nop='+ val.php +'" class="li-link"><div class="circle-img"><img src="'+ val.logo + '" /></div><div class="merchant-info"><h1>'+ val.node_title +'</h1><p>You Have '+ val.php +' Binggz</p></div><div class="more-icon"></div></a> </li>');
}); 

}, false);
    $.getJSON('mywebsite/views/services_merchant_mobile', function(data) {
        localStorage.setItem('foo', JSON.stringify(data));

var items = [];
$.each(JSON.parse(localStorage.getItem('foo')), function(key, val) {
    if(!(val.php)){val.php=0;}
$('ul.get-mertchant').append('<li> <a href="azkadenya.html?id=' + val.nid + '&nop='+ val.php +'" class="li-link"><div class="circle-img"><img src="'+ val.logo + '" /></div><div class="merchant-info"><h1>'+ val.node_title …

我正在尝试在我的ios phonegap应用程序上设置facebook connect插件,我按照以下链接中的步骤操作

我正在尝试使用 JS 生成 6 位代码。

它必须包含 3 个数字和 3 个字符。

这是我的代码

var numbers = "0123456789";
var chars = "acdefhiklmnoqrstuvwxyz";
var string_length = 3;
var randomstring = '';
var randomstring2 = '';
for (var x = 0; x < string_length; x++) {
    var letterOrNumber = Math.floor(Math.random() * 2);
    var rnum = Math.floor(Math.random() * chars.length);
    randomstring += chars.substring(rnum, rnum + 1);
}
for (var y = 0; y < string_length; y++) {
    var letterOrNumber2 = Math.floor(Math.random() * 2);
    var rnum2 = Math.floor(Math.random() …

我有$.eachFacebook好友列表.

这是$.each代码

$.each(response.data, function(index,friend) {
    alert(friend.name + ' has id:' + friend.id);
}

现在我如何将这些数据存储在数组中,就像这个数组一样

friends = [
    { "name": "John"  , "id": "1" },
    { "name": "Anna"  , "id": "2" },
    { "name": "Peter" , "id": "3" }
];

如何使用foreach创建这样的数组

$data = array(
    (object)array(
        'oV' => 'myfirstvalue',
        'oT' => 'myfirsttext',
    ),
    (object)array(
        'oV' => 'mysecondvalue',
        'oT' => 'mysecondtext',
    ),
);
