如何搜索所選日期的JSON對象？

<script src="content/personSchedule.js"></script> 
var personSchedule = [ 
    { 
     "date": "02/6/2017", 
     "title": "CEO", 
     "mondayAM": "Apple Campus AM", 
     "mondayPM": "Apple Campus PM", 
     "tuesdayAM": "Apple Campus AM", 
     "tuesdayPM": "Apple Campus PM", 
     "wednesdayAM": "Apple Campus AM", 
     "wednesdayPM": "Apple Campus PM", 
     "thursdayAM": "Apple Campus AM", 
     "thursdayPM": "Apple Campus PM", 
     "fridayAM": "Apple Campus AM", 
     "fridayPM": "Apple Campus PM", 
     "saturdayAM": "Apple Campus AM", 
     "saturdayPM": "Apple Campus PM" 
    }, 
    { 
     "date": "02/13/2017", 
     "title": "CEO", 
     "mondayAM": "Apple Campus AM", 
     "mondayPM": "Apple Campus PM", 
     "tuesdayAM": "Apple Campus AM", 
     "tuesdayPM": "Apple Campus PM", 
     "wednesdayAM": "Apple Campus AM", 
     "wednesdayPM": "Apple Campus PM", 
     "thursdayAM": "Apple Campus AM", 
     "thursdayPM": "Apple Campus PM", 
     "fridayAM": "Apple Campus AM", 
     "fridayPM": "Apple Campus PM", 
     "saturdayAM": "Apple Campus AM", 
     "saturdayPM": "Apple Campus PM" 
    } 
];

我有一個日期選擇器如何搜索所選日期的JSON對象？

<input type="date" id="date" step="7" min="2017-02-06" />

當日期改變，我要改變出現在HTML

$("#date").change(function(){ 
    var theSelectedDate = $('#date').val(); 
    console.log(theSelectedDate); 
    $.each(json.people.person, function(i, v) { 
     if (v.name.search(new RegExp(/theSelectedDate/)) != -1) { 
      alert(v.title); 
      return; 
     } 
    }); 
});

文本當我運行此我得到以下錯誤

未捕獲的語法錯誤：無效的正則表達式：缺失/

您CA使用''雖然知道，它的值是在格式YYYY-WNN（2017-W06）（年Wweeknumber） – Akxe

你會想要做這樣的事情。

凡myArray的是JSON對象，以及輸入作爲輸入

是存儲JSON文件的地方。它看起來像一個JSON對象存儲在var personSchedule –

一旦你解析JSON，你可以使用函數'Array.find'來找到你的值。或者在這種情況下，使用presArraySchedule變量而不是myArray。 – Akxe

你寫了/theSelectedDate，我認爲應該是/theSelectedDate/或其他RegExp格式。

謝謝我得到沒有錯誤，但我沒有得到任何結果。當我知道它的存在時，我的警報不會觸發。 –

你的正則表達式是錯誤的：應該像新RegExp(/ab+c/, 'i');https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp

你的情況，你想RegExp(thSelectedDate)，因爲你正在傳遞價值的RegExp()和功能在正面和背面附加\自動評估值它。如果你想獲得只有一個值或undefined，使用Array.findmethod

function getOjectForDate(date){ 
    return myArray.filter(function(value){ 
     return value.date == date 
    }) 
} 
console.log(getOjectForDate(input.val()) // returns array with every valid object
