我的代码在Google Chrome中正常运行,但在Safari中则无法运行.

我发现我需要转换yyyy-MM-dd HH:mm:ss为ISO 8601,但我没有找到解决方案来做到这一点.

在线测试链接:http://jsfiddle.net/UVgHR/

使用Javascript:

$(document).ready(function() {

    calculateMinutes();
    setInterval(calculateMinutes, 60000);

});

function calculateMinutes() {
    $('.calculateMinutes').each(function () {
        var diff = Math.abs(new Date( $(this).data('timestamp') ) - new Date());
        var minutes = Math.floor((diff/1000)/60);
        $(this).html( minutes + ' min.' );
    });
}

HTML示例:

<span class="calculateMinutes" data-timestamp="2014-02-18 15:00:48">

如何从NSDateFormatter格式中转义字符？

NSDate *currentDate = [NSDate date];
NSDateFormatter *dateFormater = [[NSDateFormatter alloc] init];
[dateFormater setDateFormat:@"dd/MM/yyyy \\a\\t HH:mm"];
NSString *dateFormated = [dateFormater stringFromDate:currentDate];

NSLog(@"%@", dateFormated);

我有两个环境AWS Elastic Beanstalk:Development和Production.

我希望这.ebextensions/app.config只能在Production环境中运行.有什么办法吗？

的app.config:

container_commands:
  01-command:
    command: "crontab .ebextensions/cronjob"
    leader_only: true

要打开Facebook Native配置文件,我可以使用:

NSURL *url = [NSURL URLWithString:@"fb://profile/<id>"];
[[UIApplication sharedApplication] openURL:url];

有什么方法可以为Instagram个人资料做同样的事情吗？

Object has been deleted or invalidated.当尝试使用属性或AFnetworking Block内部修改模型对象时,有时(很少会发生)我收到错误.任何人都可以帮我找到我做错的事吗？

错误 - 案例1:

码:

- (void)myFunction {
    Model *model = [Model objectForPrimaryKey:1];

    if (model) {
        [self updateModel:model];
    }
}

- (void)updateModel:(Model *)model {

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager PUT:@"http://www.example.com" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

        [[RLMRealm defaultRealm] beginWriteTransaction];
       model.updated = YES; // Crash: Object has been deleted or invalidated.
        [[RLMRealm defaultRealm] commitWriteTransaction];

    } failure:nil];
}

错误 - 案例2:

属性:

@property (strong, nonatomic) Model *model;

码:

- (void)myFunction {
    Model *model = …

我想知道如何在Yii Controller Action强制使用HTTPS(SSL).

我想在foreach完成后执行回调,但它不能正常工作.我怎么能这样做？

var response = [];
myArray.forEach(function(data) {
    data.asyncFunction(function(result) {
         response.push(result);
    });
}, function() {
    console.log(response); // Not being called.
});

console.log(response); // (Empty) Executed before foreach finish.

如何在Yii Framework中制定规则,只允许用户名字段中的字符az,下划线和短划线？

谢谢

模型.php

// Declare $datetime_limit
public datetime_limit;

控制器.php

// datetime_limit should be the actual datetime + 5 days
$criteria->select="DATE_ADD(NOW(), INTERVAL 5 DAY) AS datetime_limit";

错误信息：

Active record "Users" is trying to select an invalid column "DATE_ADD(NOW()". Note, the column must exist in the table or be an expression with alias.

编辑1：

我想使用关系表（多对多）过滤带有条件的查找。所以datetime_limit不能有关系events.datetime。我怎样才能做到这一点？

$criteria->select=array("DATE_ADD(NOW(), INTERVAL 5 DAY) AS datetime_limit");
$criteria->with=array('events');
$criteria->having='datetime_limit!=`events`.`datetime`';
$models=Users::model()->findAll($criteria);

我想要使​​用命令序列:

Yii::app()->user->setFlash('success', "Successful!");
Yii::app()->user->logout();
$this->redirect(array('user/login'));

用户已注销并重定向,但Setflash无效.我也尝试改变2个frist命令的顺序,但是遇到了同样的问题.如果我不注销用户,Setflash工作正常.

如何使两个命令都有效？
