jQuery - 从对象

Question

我想显示注册用户在注册时填写的开放时间：

这是'value'＆amp;它以这种方式存储在DB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value：

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);
    }
  }
};

这就是它在页面上显示的方式：

问题：

正如你可能看到的那样，星期三的日子（荷兰'woensdag'介于'dinsdag'和'donderdag'之间）缺失，因为它没有故意填写（可能是在特定的一天关闭）。因为那天没有存储，我无法显示它。

何时我会显示空值的缺失日？

Answer 1

不是循环遍历 的数据，而是遍历您想要的数据，然后显示与之匹配的数据

{{1}}
