Javascript jQuery-填写对象中缺少的周天数值

我想显示注册用户在注册期间填写的开放时间：

这是“

值”

”&它以这种方式存储在数据库中：

[
{"day":"Maandag","daylabel":"Maandag","fromtime":"15:30","fromtimelabel":"3:30 pm","totime":"22:00","totimelabel":"10:00 pm"},
{"day":"Dinsdag","daylabel":"Dinsdag","fromtime":"15:30","fromtimelabel":"3:30 pm","totime":"22:00","totimelabel":"10:00 pm"},
{"day":"Donderdag","daylabel":"Donderdag","fromtime":"15:30","fromtimelabel":"3:30 pm","totime":"22:00","totimelabel":"10:00 pm"},
{"day":"Vrijdag","daylabel":"Vrijdag","fromtime":"15:30","fromtimelabel":"3:30 pm","totime":"22:00","totimelabel":"10:00 pm"},
{"day":"Zaterdag","daylabel":"Zaterdag","fromtime":"09:30","fromtimelabel":"9:30 am","totime":"+00:00","totimelabel":"12:00 am (next day)"},
{"day":"Zondag","daylabel":"Zondag","fromtime":"09:30","fromtimelabel":"9:30 am","totime":"+00:00","totimelabel":"12:00 am (next day)"}
]

这是我解析

值的函数

：

config.profile.core.parseAvailability = function(value){
  if(value){
    try {
        var availabilityDays = JSON.parse(value);
        $jq.each(availabilityDays, function(index, day) {
            $jq('#availability').append('<div class="col-sm-5">'+day['daylabel']+'</div><div class="col-sm-7">'+day['fromtime']+' - '+day['totime']+'</div>');
        });
    } catch (error) {
        console.error(error);
    }
  }
};

config.profile.core.parseAvailability=函数（值）{
如果（值）{
试一试{
var availabilityDays=JSON.parse（值）；
$jq.每个（可用性天数，功能（索引，天数）{
$jq（“#可用性”）.append（“+day['daylab']+”+day['fromtime']+'-“+day['totime']+”）；
});
}捕获（错误）{
控制台错误（error）；
}
}
};

这就是它在页面上的显示方式：

问题：

正如你可能看到的，星期三的日期（荷兰语“woensdag”介于“dinsdag”和“donderdag”之间）不见了，因为它不是故意填写的（可能在特定的一天关闭）。因为那天没有存储，所以我不能显示它

我如何用空值显示缺失的日期？

与其循环查看已有数据，不如循环查看所需数据，然后显示与之匹配的数据

var days = ['Maandag', 'Dinsdag', 'Woensdag', 'Donderdag', 'Vrijdag', 'Zaterdag', 'Zondag'];
var availabilityDays = JSON.parse(value);

for (var day of days) {
    var details = availabilityDays.find(function (detail) {
        return detail.day == day;
    });

    var detailsText = '';

    if (details) {
        detailsText = details['fromtime']+' - '+details['totime']
    }

    $jq('#availability').append('<div class="col-sm-5">'+day+'</div><div class="col-sm-7">' + detailsText + '</div>');
}

var-days=['Maandag'，'Dinsdag'，'Woensdag'，'Donderdag'，'Vrijdag'，'Zaterdag'，'Zondag']；
var availabilityDays=JSON.parse（值）；
对于（var天数）{
var details=availabilityDays.find（函数（细节）{
返回detail.day==天；
});
var detailsText=''；
若有（详情）{
detailsText=详细信息['fromtime']+'-'+详细信息['totime']
}
$jq（“#可用性”）。追加（“”+day+“”+detailsText+“”）；
}

与其循环你所拥有的数据，不如循环你想要的数据，然后显示与之匹配的内容

var days = ['Maandag', 'Dinsdag', 'Woensdag', 'Donderdag', 'Vrijdag', 'Zaterdag', 'Zondag'];
var availabilityDays = JSON.parse(value);

for (var day of days) {
    var details = availabilityDays.find(function (detail) {
        return detail.day == day;
    });

    var detailsText = '';

    if (details) {
        detailsText = details['fromtime']+' - '+details['totime']
    }

    $jq('#availability').append('<div class="col-sm-5">'+day+'</div><div class="col-sm-7">' + detailsText + '</div>');
}

var-days=['Maandag'，'Dinsdag'，'Woensdag'，'Donderdag'，'Vrijdag'，'Zaterdag'，'Zondag']；
var availabilityDays=JSON.parse（值）；
对于（var天数）{
var details=availabilityDays.find（函数（细节）{
返回detail.day==天；
});
var detailsText=''；
若有（详情）{
detailsText=详细信息['fromtime']+'-'+详细信息['totime']
}
$jq（“#可用性”）。追加（“”+day+“”+detailsText+“”）；
}
